Re: [ECOS] guide for running eCos in ARM PID

["Young Jay" <young_jay at sohu dot com>]

Hello, Jonathan:

I just followed the instructions from http://sources.redhat.com/ecos/docs-latest/user-guide/setup-arm-pid.html,
but when I progressed to make redboot written into the Flash on PID board, I got an error message as follows:

"$ arm-elf-gdb -nw gdb_module.img
GNU gdb 5.3 (eCosCentric)

This GDB was configured as "--host=i686-pc-cygwin --target=arm-elf"...
(no debugging symbols found)...

(gdb) target rdi s=com1
RDI_open: undefined error message, should reset target
RDI_open failed

(gdb)  "

My board is properly powered up and I have connected it with a serial cable to 
the host computer. Also I made correct jumper and switch set referring to the user
guide for PID board. But it seems that the communucation channel hasn't been 
established. Could you tell me if there is still something to be configured in order
to program redboot with ROM startup mode into the flash on board? Thanks a lot!



Best regards,
Young Jay
