Hi Edvin,

Apologies for the late reply but I got distracted with other work. When I get a bit of spare time, I'll try your suggestion to check the end_addr location when the application startup fails and get back to you with my findings.

Thanks.

Hello,

Did you erase the flash before you flashed the bootloader and application?

Ideally, if you start with a blank flash, and flash the BL, APP and the SD, then the fds module should check whether or not there is a bootloader present:

fds_init() -> flash_subsystem_init() -> flash_bounds_set() -> flash_end_addr():

uint32_t end_addr = (bootloader_addr != 0xFFFFFFFF) ? bootloader_addr : (code_sz * page_sz);

When it fails, what is end_addr? Is it moved down according to the bootloader address?

Best regards,

Edvin
