 sir,

   I am trying to run redhat ecos on the ATMEL AT91
Evaluation
   Board(EB40), For that one I created executables
like 
   arm-elf-ar, arm-elf-gdb, .....like that.

   When I was trying to connect target board to host
system
   through serial port using minicom, it is showing
like 
  
 arm-elf-gdb redboot_RAM.elf
(gdb) tar rdi s=/dev/ttyS0
Angel Debug Monitor (serial) 1.04 (Advanced RISC
Machines SDT 2.5) for AT91EB40 
Angel Debug Monitor rebuilt on Apr 07 2000 at 12:40:31
Serial Rate:   9600
Connected to ARM RDI target.
(gdb) set $ps=0xd3
(gdb) lo

(gdb) c
Continuing.

At this point, interrupt the Angel session and start
minicom.

RedBoot> load -m ymodem -b 0x02040000

at this moment I am getting like
CCCCCCCCC........can't load: Timed out


  can anyone give solution for above error, I would
like to say
  thanks in advance. Please try to give solution for
above error.
   
  if I want to use Tftp to download the file to memory
please suggest
  us how to configure host and target.

  I hope someone will give reply for this.


With regards,
Narendra Babu.
