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_io: Writing 1 "\r" cu: fconn_io: Wrote 1 of 1, 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.
