When I try putting any breakpoint on my code to watch some variables, Keil will never halt that breakpoint. When I click pause in the debug session, the disassembler shows a loop on Branch + WFE, even though I'm not using sd_wait_event or something like that. I'm using the SoftDevice 8.
Any suggestions?
Did you check the IROM and IRAM settings of the projects? How did you make sure that your program is running? I am sorry for such basic questions, but we start from the basics , most of the time its some simple thing that is going wrong ;)
I am not sure what your whole project is doing, I just concentrated in trying to find why your project was not able to debug. In your bootloader_settings.c file you have this line
uint32_t m_uicr_bootloader_start_address __attribute__((at(NRF_UICR_BOOT_START_ADDRESS))) = BOOTLOADER_REGION_START;
which means that when you flash your code, 0x10001014 will be written with 0X3C000. When this register is written, softdevice tries to find the vector table there and if it did not find it, then it goes to sleep. Seems like you have merged application with bootloader, this is OK, but softdevice is still expecting bootloader at 0X3C000 because it sees that the register says that the bootloader is present at that address. If you remove the attribute on the variable i mentioned above, I was able to debug your application.
you will be able to do the same
