Hi.
I'm using a licensed µVision 4 and I'm trying to improve the programming of my devices.
First, this is how I do it now:
I create a AFX program file with µVision4 and I can flash the devices (usually Cortex M3) using an ULINK2 Programmer and the JTAG of the devices. This is great for debugging as the AFX-file contains debugging information.
Besides this, I need to create a checksum of the binary and add the sum to the flash of the devices. Therefore, I create a BIN file from the AFX file, calculate the checksum and program the flash of the device using a serial connection and the internal bootloader. This way I can add the checksum to the internal flash.
So, the problem is:
I need to switch on the boot-Pins for activating the internal boot loader of the STM32 (In my case, I have to press and hold some buttons on the device), this is a lot of annoying work. I would prefer a solution using the ULINK2 (and JTAG).
Maybe someone knows if there is a solution for one of the following scenarios:
1.) I can add the checksum (some numbers) to the AFX file and use the ULINK2 for programming and for adding flash (tool for calculating checksum from BIN or HEX file which is created automatically by µVision4, is already working). I won't need to activate the Bootloader of the device this way.
2.) I can convert AFX->BIN (done by fromelf, etc.), change BIN file (by adding checksum to the end) and convert BIN->AFX (by adding debugging information somehow??) and than use the ULINK2 for programming.
3.) Maybe someone else has a good idea how to do this automatically?
Any help would be greatly appreciated.
