I load user app at 0x2000 with full erase, then load bootloader with only sector erase. Start debug from bootloader and see systick polling, then after timeout, jump to user app which should run systick interrupt and allow break point in bootloader to see interrupt result- not happening yet. Secondary bootloader for NXP LPC1114/5 Reference NXP app note 10995 Need to use same interrupts in bootloader and user application. According to NXP AN10995, int vector is only at location 0, and no vector offset reg is available offsetting to other int vector.

Over the multitude of years of service, my 2009 Mac Pro has endured many supported and unsupported software updates, OS upgrades, hardware upgrades, firmware upgrades, re-installs, wipes, Boot Camp installs, boot loader changes, and so on and so on. Over that time and over those many changes, at some point, my logic board lost its marbles and simply 'forgot' its serial number. Here's how to get your Mac to 'remember' its serial number once more!.

The problem with not having a serial number For quite some time I had no issues with my Mac not knowing its serial number or revision (year of manufacture). Everything worked fine. I could install programs, log into the App store, iMessage friends and colleagues, and everything else needed in my Mac environment. However, a time came after a certain update or upgrade (I can't remember which, since for the most part, everything still just worked) certain services like iMessage and FaceTime would no longer allow me to log in to their services. Strangely some other services logged in just fine.

Words of warning You really shouldn't do this fix. But if you are insisting on getting it done there are a few caveats before delving into this fix. First, you not only need a valid serial number, but you need a valid serial number for the hardware you will be performing it on.

The serial number CAN'T be transferred between machines. Therefore this fix is truly for your genuine Apple hardware that has lost it's serial number along the way on its logic board.

You'll be using the same serial number that the computer originally had when you first purchased it. Second, there is no room for error. You only get one chance at inputting the proper serial number during the 'write' phase of the how to. If you mistype any part of it, you'll likely end up with a non-bootable system. DO NOT PERFORM THIS FIX IF YOU CANNOT LIVE WITH A NON-WORKING MACHINE. Third, and most importantly, I'll be suggesting (but not providing) software that may or may not be for Apple's internal use only.

I do not know the legality of having access to this software or using this software. Do not use this software if you worry about the copyright or legal issues that may or may not be involved with running said software. Fourth, If this doesn't work for you and you get a non-functional system. Don't blame us. I told you to not perform this fix. Fifth, if you have an Apple warranty that's still valid, call Apple to fix the serial number issue. Don't use this method.

This will likely void any valid warranty. Finally, don't use this fix. Get your serial number Getting your serial number should be a straight forward affair. When you buy your Apple for Apple.com, you'll get a receipt via email with your serial number on it. The box that your Mac came in will also have a serial number on a card within the box. You Mac itself, will have the same serial number somewhere either on, in, in back of, or under its casing.

There is literally very little excuse for you to not have access to your serial number. Get a USB key For this to work, you'll need to be able to boot off of a secondary device such as a USB. The files are very small so nearly any USB key will work. I used the from Amazon for $15 in my example. Get the software The software I'm using but am not providing is called the Blank Board Serializer. The fix.

Format the USB drive with with the FAT filesystem. Unpack the Blank Board Serializer program to your disk.

Using Disk Utility, Restore the unpacked dmg file to your USB drive. Click Done.

Shutdown your Mac. Reboot your Mac whilst holding the option key on your keyboard. You'll be presented with multiple boot devices, choose the EFI USB key. Click to Accept the usage agreement. Enter your Serial Number WITHOUT ERRORS. Truly make certain there are no errors here.

Remember that Zeros (0) and 'O's' look very similar. Click Enter. Click Yes for each following prompt.

Click Proceed. Click Restart.

Final comments Why was I able to log in to all of my services before the unknown update is anybody's guess. Is it because Apple wants only genuine Apple computers accessing their networks? If so then why would some iCloud services work whilst others didn't? In any case, Once a valid serial number was re-installed on my logic board, everything worked as seamlessly and as beautifully as expected. What about you? Are you living with no serial number? How has it affected you?

This tutorial was written for AVR microcontrollers with an Arduino bootloader using ICSP pins. If you are using an ARM microcontroller with SWD pins, you will need a dedicated programmer (i.e. Atmel JTAG ICE 3 or Atmel-ICE) to connect to the SWD port. Do you have a bricked Arduino that won’t accept code anymore? Or, maybe you wrote your own firmware and would like to upload it to your Arduino? Or, maybe you just want to learn more about the inner-workings of Arduino, AVR, and microcontrollers in general.

Well, you’re in luck! This tutorial will teach you what a bootloader is, why you would need to install/reinstall it, and go over the process of doing so. Suggested Reading You may want to check out these tutorials before continuing down the bootloader path. What is a Bootloader? Are great little ICs, but they can be a bit tricky to program.

You need a special programmer and some fancy.hex files, and its not very beginner friendly. The Arduino has largely done away with these issues. They’ve put a.hex file on their AVR chips that allows you to program the board over the, meaning all you need to program your Arduino is a USB cable. The bootloader is basically a.hex file that runs when you turn on the board. It is very similar to the that runs on your PC. It does two things. First, it looks around to see if the computer is trying to program it.

If it is, it grabs the program from the computer and uploads it into the ICs memory (in a specific location so as not to overwrite the bootloader). That is why when you try to upload code, the Arduino IDE resets the chip. This basically turns the IC off and back on again so the bootloader can start running again. If the computer isn’t trying to upload code, it tells the chip to run the code that’s already stored in memory. Once it locates and runs your program, the Arduino continuously loops through the program and does so as long as the board has power. Why Install a Bootloader? If you are building your own Arduino, or need to replace the IC, you will need to install the bootloader.

You may also have a bad bootloader (although this is very rare) and need to reinstall the bootloader. There are also cases where you’ve put your board in a weird setting and reinstalling the bootloader and getting it back to factory settings is the easiest way to fix it.

We’ve seen boards where people have turned off the serial port meaning that there is no way to upload code to the board, while there may be other ways to fix this, reinstalling the bootloader is probably the quickest and easiest. Like I said, having a bad bootloader is actually very very rare.

If you have a new board that isn’t accepting code, 99.9% of the time its not the bootloader. For the other 1% of the time it is, this guide will help you fix that problem. Note: The following programmers that have been retured also can be used. The AVR Pocket Programmer or most cheaper options will work just fine for most applications, but they may have problems with some boards, specifically ones with lots of memory like the ATMega2560 based boards.

Option 2: Using the Arduino as a Programmer The other option is grabbing an Arduino Uno (or Duemilanove). If you go into the Arduino IDE you will see an example sketch called ‘Arduino as ISP.’ If you upload this code to your Arduino, it will basically act as an AVR programmer. This isn’t really recommended for production of boards, or boards with lots of memory, but, in a pinch, it works pretty well. Also as of this writing the code only works on ATmega328 boards.

Maybe one day it will work on the Leonardo or Due, but not yet. Hardware Hookup In-Circuit Serial Programming (ICSP) It’s very uncommon to program ICs before they are soldered onto a PCB. Instead, most microcontrollers have what’s called an in-system programming header.

Particularly, some IC manufacturers, such as Atmel and Microchip, have a specialized ISP method for programming their ICs. This is referred to as in-circuit serial programming.

Most Arduino and Arduino compatible boards will have a 2x3 pin ICSP header on them. Some may even have more than one depending on how many ICs live on the PCB. It breaks out three of the pins (MISO, MOSI, SCK), power, ground, and reset. These are the pins you’ll need to connect your programmer to in order to reflash the firmware on your board.

Here we have the Arduino Uno R3. It has two ICSP headers: one for the ATmega16U2 and one for the ATmega328. To reflash the bootloader on this board, you would use just the ICSP header for the ATmega328. On some smaller boards you may not see this connector, but the pins should be broken out elsewhere. Whether you’re using an, the ISP pins should be accessible in one form or another. Some boards might only have test points for the ISP header. If this is the case, you may want to consider getting an.

This kit allows you to temporarily make a good connection with test test points in order to reprogram your IC. ⚡ Power Your Target Arduino! Make sure to power your target Arduino. Otherwise, you will not be able to flash the.hex file to your target.

Here’s a table to help clarify which connections go where. Depending on the Arduino, you may have access to the ICSP pins only on the 2x3 ICSP header. Make sure to refer to the board layout for more information on the.

Note: This example assumes you are using the latest version of the Arduino IDE on your desktop. If this is your first time using Arduino, please review our tutorial on The easy way to upload the bootloader involves using the Arduino IDE.

Upload Arduino as ISP Grab a known good RedBoard or Arduino Uno. Open your Arduino IDE. In your menu, select File Examples 11.ArduinoISP ArduinoISP to open up the Arduino as ISP sketch Select the COM port for your Arduino as ISP. The COM port may be different depending on how it enumerated on your computer. Upload the code to your Arduino to turn it into a AVRISP.

Burning a Bootloader to Your Target Leave the Arduino as ISP (i.e. Your programmer) connected to your computer. If you have not already, connect your target Arduino. Then select the board definition for your target Arduino under Tools Board. Select the programmer that you are using under Tools Programmer. In this case, our programmer is an Arduino as ISP so select ArduinoISP.

You will also need to select the COM port that the Arduino as ISP is connected to if you have not selected the COM port already. Finally, select Burn Bootloader. This will take the board you selected in the Arduino IDE and look up the associated bootloader in the board.txt file.

Then, it will find the bootloader in the Arduino IDE's program folder (specifically “ Arduino hardware arduino avr bootloaders”) and install it. This only works if the board is installed correctly in the IDE and you have the correct bootloader. If for some reason you want to use a bootloader that isn’t installed in the Arduino IDE, visit the next section.

However, it’s probably easier to just install the bootloader from the Arduino IDE. For those who are curious about settings such as fuse bits, have no fear. Arduino takes care of all the messy details for you when you burn bootloaders through it. Uploading Code - Hard Way The hard way is for those people who want to use the.

This method may be more preferable if you are modifying and recompiling and don’t want to have to keep updating the IDE, but otherwise it's pretty unnecessary. Again, you will need to get the programmer and hook everything up. In this example, we are using avrdude on Windows. There are three steps to this process:. Set Fuse Bits (i.e. Low, High, and Extended).

Flash.hex File. Set Lock Bits The first step involves setting the fusebits. Fusebits are the part of the AVR chip that determine things like whether you are using an external crystal or whether you want brown out detection. The commands listed below are specifically for the Arduino Uno using an ATMega328, they will probably work on some other similar boards such as the Duemilanove, but make sure you know what you are doing before playing with fusebits. All the required fuse bits are listed in the boards.txt file for different boards.

Again, if you have a boards.txt file installed then just use the Easy Way. The second step is actually uploading the program. The final step is setting the lock bits. Note: These fusebits will not work on a 3.3V/8MHz board.

If you are using a different microcontroller, you will also need adjust the. Pocket AVR Programmer If you are using the AVR Pocket Programmer to program your target Arduino Uno, type the following commands in the command line to set the fuse bits.

Language:bash avrdude -b 19200 -c usbtiny -p m328p -v -e -U efuse:w:0x05:m -U hfuse:w:0xD6:m -U lfuse:w:0xFF:m Once the fuse bits are set, we can flash a compiled.hex file to the target board and set the lock bits. Enter the following in a command line. Make sure that you are in same directory as your.hex file and adjust the.hexfilename.hex that you are using to flash for your target. To flash the Arduino Uno Bootloader, head over to the Arduino program folder.
