Thanks, Wolfgang for the response.
I wonder if the problem is my hardware?
My hardware is an STK8xxL.400 Universal Application Baseboard with a TQ minimodule MPC860P/8Mb Flash/16 MB SDRAM. I have connected the serial port on my PC to the "middle" serial port connector on the baseboard. Is this hardware known to cause problems ?
The PC is a Dell Optiplex with SuSe 8.2; it has a serial port on back of the case.
I have also tried to use the "loadb" command (with Kermit on the PC) over the serial port without success. Two packets are sent with 12 retries before Kermit gives up.
I have also tried TFTPBOOT with the following unusual results:
=> tftpboot 40040000 /tftpboot/uImage
Using SCC ETHERNET device TFTP from server 192.168.5.1; our IP address is 192.168.5.6 Filename '/tftpboot/uImage'. Load address: 0x40040000 Loading: *TX timeout TX not ready TX timeout T TX not ready TX timeout T TX not ready TX timeout TX not ready TX timeout T TX not ready TX timeout TX not ready TX timeout T TX not ready TX timeout TX not ready TX timeout T TX not ready TX timeout T TX not ready TX timeout TX not ready TX timeout T TX not ready TX timeout T TX not ready TX timeout T TX not ready TX timeout TX not ready TX timeout T TX not ready TX timeout TX not ready TX timeout
Retry count exceeded; starting again Unable to discover phy!
I note that the "orange link light" is always lit on the baseboard, but that the "green data light" seldom flickers at all.
Does any of this point to a specific kind of problem with my hardware ?
Thanks, again.
Charles.

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.
Why didn't you use the current code from CVS as recommended in the DULG?
I built U-Boot using
make TQM860L_config
This is OK for recent versions of U-Boot.
I now realise that I have FEC on my board, and should have used
Make TQM860L_FEC_config
Obsolete and does not exist any more.
but I did not expect that this would impact on the serial port comms. Perhaps this is the source of the problem ???
No.
All of this went well - I can log into U-Boot and execute commands
such
as flinfo.
Then everything is fine.
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.
Why do you chose the slowest and most unreliable way top download the image? Use TFTP, or at least kermit binary protocol instead.
Has this problem been seen before? Is there anything that can be done
to
work around it?
Did you configure your UUCP tools as recommended? Are you using a real serial port or one of those crippled USB adapters?
