[U-Boot-Users] Srec problem and TQM860

[Charles J Gillan]

Folks,

    I have encountered a problem with downloading Linux to my TQM860L
board using S records via the serial port. Any help or suggestions
would be greatly appreciated.

    Last week I followed the ELDK instructions to replace the TQ Monitor
on my board with Das U-Boot. I use ELDK 3.0 but download the U-Boot
1.1.1
source and compiled it rather than the 1.0.2 source delivered with ELDK
3.0.

I built U-Boot using 

              make TQM860L_config

I now realise that I have FEC on my board, and should have used 

              Make TQM860L_FEC_config

but I did not expect that this would impact on the serial port comms.
Perhaps this is the source of the problem ???

I used "cu" on my SuSe 8.2 PC to download U-Boot as SRECs over the
serial port.
 
All of this went well - I can log into U-Boot and execute commands such
as 
flinfo.

I then built the linux 2.4.24 kernel that comes with ELDK 3.0 and
converted
this to S records. My downloads fail at the seventh S record (see
attached
debug from "cu" at end of file); record 6 required a retry.

7 cu: fconn_io: Writing 44
"S2140000507800E45A0F701367767FAB3FB6843D4452"
cu: fconn_io: Wrote 44 of 44, read 0 of 16383

cu: fconn_read: Read 16 "## S-Record down"  <----------- Error starts
here
cu: fconn_read: Read 8 "load abo"
cu: fconn_read: Read 9 "rted\r\n=> "

I have also tried using a RedHat PC which has a different implementation
of
"cu". The same problem exists.

Has this problem been seen before? Is there anything that can be done to
work around it?

Regards and thanks,

Charles.
