[U-Boot-Users] Srec problem and TQM860

[Charles J Gillan]

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

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.

Why didn't you use the current code from CVS as recommended in the DULG?

This is OK for recent versions of U-Boot.

Obsolete and does not exist any more.

No.

Then everything is fine.

Why do you chose the slowest and most unreliable way top download the
image? Use TFTP, or at least kermit binary protocol instead.

Did you configure your UUCP tools as recommended?  Are  you  using  a
real serial port or one of those crippled USB adapters?
