How to stop breaking at reset
I am developing a number of projects for STM32 processors using Eclipse, gcc, gdb and an Olimex ARM-USB-OCD jTag dongle. All works well, but every time I relaunch the project in debug mode the code stops at address 0x08000000. The debug window
this always happens. Furthermore I suspect it is using up one of the 6 breakpoints provided by the STM32, which restricts debugging. I launch gdb with the following commands: target remote localhost:3333 monitor reset init load monitor reset init break main The first breakpoint it should

how can i debug code in ram ?

I did test with STM32F103C8T6 ($3 chinese board, known as blue pill). The only thing I had to do is to write my linker script to put everything in RAM, then: 1. Put the jumpers at BOOT0 & BOOT1 pins to boot from RAM.
