CubeIDE Execute command before debug

[LSpad.1]

Hi,

i would like to execute command after i click the debug icon, but before the debug starts.

In particular:

• I have an app with a bootloader. The bootloader check the CRC of the firmware before start it.
• Right now i generate, thanks to post build operation, a binary file with header, firmware and footer, a complete binary.
• I have disable the Download in the Debug configuration, so the debugger does not flash the firmware.
• I need a point where place the command for flashing the complete firmware with the header and the footer. This point should be before the debug session start, and after i click the debug icon.

Do you think it is possible? How can i do that?

Thank you in advance

Instead of post/pre build commands use CDT files makefile.init, makefile.defs and makefile.targets. For CRC you may add target to /makefile.targets (file must be created!):

CRC_Tool := 'C:\Tools\crc.exe'
 
crc: all
	-@echo 'Calculating CRC'
	$(CRC_Tool) $(wildcard *.bin)

Press Shift-F9, add target crc, execute crc

To debug application, you don't need a bootloader, CubeIDE will start application from ld flash address, but you have to add code to move the stack as first lines to main:

#define FLASH_START 0x800....
....
int main()
{
 /* USER CODE BEGIN 1 */
 __disable_irq();
 SCB->VTOR = FLASH_START | VECT_TAB_OFFSET;
 __DSB();
 __enable_irq();
 ...

Hi, thanks for the answer.

It is not clear how i can create a CRC based on the binary file before i create that binary file. Are you sure is it possible with CDT files?

Regarding the debug: it is clear that if i launch debug from the IDE the debug and the application work. But if i reboot the board, the bootloader does not recognize the CRC of the application, and it won't start anymore.

crc: all

command(s)

This means:

• build "all" target first if something changed
• Run crc command(s)
