Re: [U-Boot-Users] Srec problem and TQM860

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?
