Fwd: STM32 ROMINT don't run

[Samuel Charnet <samcharnet at gmail dot com>]

Hi,

I want to try the ecos OS. My board come from waveshare, it is based
on stm32f407ig core ( http://www.wvshare.com/product/EVK407I.htm )

After some days I have ecos from CVS compiled. With the configtool I
have created my library with the stm3240 template and i have modified
the startup type to ROMINT

I have a simple thread which blink a led. I can upload the binary file
to the stm32 (i use the last openocd from source and olimex
arm-usb-ocd-h jtag device)

Unfortunately the led don't blink. With gdb i can't break on any
function and the stack seems broken.

The objdump seems ok but i am not a veteran with embeded developpment.

Could you give me some hints, i do not know where to search.. thanks in advance.

This is a gdb output :

(gdb) b cyg_user_start
