custom bootloader

[NWeis.19]

Hi,

I have created in the past several custom bootloaders with KEIL and IAR for STM32F2,F4 and F7

I am now working on the WB55 with Atollic 9.3

I have a boot loader skeleton, a running application each running as stand alone without issues.

I have set the VTOR register and updated the linker files.

I have triad to follow the Atollic document "Working with bootloaders on Cortex-M devices" but so far with no sucess.

When the bootloader does the jump the application is not running ..

Is there any other document or example for the WB55 ??

Thanks,

Noam.

Looks like we have both asked a similiar question in the last while (https://community.st.com/s/question/0D53W000004nbpiSAA/custom-bootloader-testing-debug). Wondering how we can help each other out.

It seems that I have some strange issue with the project itself ?

I have created two new projects... One only toggle a LED and the second is acting as bootloder.

The "bootloader" does nothing beside jumping to the application.

The above works !

If I do the same with the same addresses in my own application the application is not running.

Same linker settings, same VTOR definitions

Any ideas ????
