[ECOS] asking for help

[narendra babu]

 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
Loading section .rom_vectors, size 0x40 lma 0x2020000
Loading section .text, size 0x7fd8 lma 0x2020040
Loading section .rodata, size 0x15a0 lma 0x2028018
Loading section .data, size 0x2e4 lma 0x20295b8
Start address 0x2020040 , load size 39068
Transfer rate: 6250 bits/sec, 500 bytes/write.
(gdb) c
Continuing.

At this point, interrupt the Angel session and start
minicom. 
RedBoot> ve
RedBoot(tm) bootstrap and debug environment, version

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.

At this point you need to start your ymodem download from the host.

These C's are the target trying to handshake with ymodem on the
host. Since you have not started ymodem, it fails...

Once you do start the ymodem transaction on the host, make sure the baud
rates match (38.4k,No parity, 8 data) and that hardware handshaking is
disabled.

[narendra babu]

 sir,

   Thank you very much for your reply, As you told we
need to start ymodem before
   we go to minicom, so that  I was installed lrzsz
package in my system and trying to 
   start ymodem, how to start ymodem before we go to
minicom? As we don't know that 
   much about this, can you please suggest us how to
use this ymodem in minicom and 
   make files download  to target.
  
   please give us reply, we will wait for your
valuable reply  to proceed further. 

With regards,
Narendra Babu.
