Bootloader jump problem
Posted: Sat May 06, 2017 5:32 pm
Hello Giovanni,
I'm using STMF105 and have a problem when I try to jump from bootloader to application.
Bootloader jumped fine when my application was with FreeRTOS, and now jumps fine only when I do blink tests in chibiOS.
Application runs fine when I load it from GDB, but when I run "monitor reset halt" bootloader fails to jump.
Application:
Inside chconf.h:
In linker file:
Bootloader does only jump AND does not use chibi os:
Maybe I have to set explicitly the main stack pointer in Application main(), or I should enable interrupts?
I've tried various scenarious with __enable_irq() and set_MSP inside application main but with no luck.
Please advice.
Thank you in advance!
