Hi,
I have made Redboot up and running in my STM32 Dev board. But unfortunately I found it's quite difficult to debug the eCos applications on my board.
My Dev boards is based on stm32f103vet6, and there's no external RAM in the board, only 2M NOR flash is available.
Because there's only 64KB RAM in the system, I found it's impossible to debug my eCos application with Redboot. So I tried to debug applications with GDB. I can load the application (smaller than 64KB) to RAM, and sometimes can debug it. But most time the GDB session would hang...
By the way, OpenJTAG was used in my test.
Does someone have good idea about the debugging?
Thanks.
Happy hacking!
/Peng
