Hello,
I followed the "DFU over UART" exercise of the intermediate lesson 9, and I have problems with launching the main application. I'm using nRF54L15-DK board, SDK v3.1.0. At Step 4 (Test Serial Recovery), the behavior is already different from what is instructed: "When you start the kit normally, you see LED1 blink as normal (main)." While I can enable the Serial Recovery and proceed with other steps, the microcontroller seems to never exit the bootloader, the blinky LED code doesn't run. I confirmed this by debugging with gdb and including bootloader symbols:
west debug (gdb) file build/mcuboot/zephyr/zephyr.elf A program is being debugged already. Are you sure you want to change the file? (y or n) y Load new symbol table from "build/mcuboot/zephyr/zephyr.elf"? (y or n) y Reading symbols from build/mcuboot/zephyr/zephyr.elf... (gdb) c Continuing. ^C Program received signal SIGTRAP, Trace/breakpoint trap. main () at /home/davidoglu/ncs/v3.1.0/bootloader/mcuboot/boot/zephyr/main.c:631 631 FIH_PANIC;
The example does not work because the bootloader gets stuck in FIH_PANIC call.
Do you have any suggestions?
Regards,
Denis
