REDBOOT error

REDBOOT error

[Rohit Agarwal]

I am trying to compile a simple C code for my arm processor IXDP425.

the contents of my_file.c which i wish to run on the arm processor is

/* this is a simple hello world program */
#include <stdio.h>

int main(void)
{
 printf("Hello, eCos world!\n");
 return 0;
}

the steps that i follow are as listed below.

1. make
 (the Makefile was already present in the directory)


2. arm-elf-objcopy -O srec my_file my_file.srec

this gives me my_file.srec

3. after that i try to load this file using redboot (launched from
minicom) by giving the folowing command

Redboot> load -v -m yModem

4. then i transfer my_file.srec using the Y MODEM protocol. the file
gets transferred.

When the transfer is complete, i get a sound from the IXDP425 and the
following message

RedBoot> load -v -m yMODEM
Entry point: 0x00080040, address range: 0x00080000-0x0008868c
xyzModem - CRC mode, 777(SOH)/0(STX)/0(CAN) packets, 11 retries

5.  thwn when i type go, i get the following error

RedBoot> go
$T050f:00080044;0d:0ffd0fec;#1b

on pressing any key, the garbage string gets repeated

RedBoot> go
$T050f:00080044;0d:0ffd0fec;#1b$T050f:00080044;0d:0ffd0fec;#1b$T050f:00080044;0

Can anyone tell me what should i do?

the 'garbage string' is gdb protocol, maybe you should attach gdb to your 
target and debug the problem. 

if its happening when you type 'go' then your crashing someplace in startup, 
is probably a configuration problem spesific to your board.

i would also suggest asking on the redboot mailing lists for help with 
redboot, not the gdb ones.
