[ECOS] I have a problem with "go" command from RedBoot on AT91EB40 target

[Gozman Florian Leonard]

Hi everyone,

Would like to have your idea on the following:

My target is: AT91EB40
My OS: Linux RedHat 7.0
My eCos: eCos v. 1.3.1 <- downloaded  with cvs (the last version which
support my board)
My GCC: v. 3.0
My GDB: Insight 5.0

I ready installed RedBoot and I tried to run the following program:

 // led_blink.c
#include <stdio.h>

extern void set_leds(int val);

int main(void)
{
  int i=0;
  while(1)
  {
    set_leds(0x04);//red LED
    for(i=1;i<100000;i++);
    set_leds(0x02);//green LED
    for(i=1;i<100000;i++);
  }

  return 0;
}

// end of led_blink.c

within it with "go" command as follow (using minicom from Linux):

RedBoot> load -m y -b 0x02040000      // select the "led_blink.srec"
file and sent it
oint: 0x02020040, address range: 0x02020000-0x02026c4c    // receive
from serial port
xyzModem - CRC mode, 653(SOH)/0(STX)/0(CAN) packets, 6 retries   //
receive from serial port

RedBoot> go  // blocks !!!  (none from the following commands works:
"go", "go 0x02040000" and "go 0x02020040")

This program runs fine with GDB.

So, I don't know what is the error.

Pleace somebody help me.

Thanks !

I solved my problem. The commands that should executed are:
RedBoot> load -m y     // select "led_blink.srec" file and then sent it

RedBoot> go

Works fine.
