Hello,
I have uploaded a hijacked kernel v270 some time ago, and it did work. Now when I try do upload a new kernel (I mean any kernel: hijacked v338, or Empeg's car-developer-v2.0beta13) it will not work. I had some problems with external power supply, so I am afraid it could destroy something. The player (MK2a) seems to work, except that left half of the VFD is dead (see another topic).
I am trying to upload from linux, using download.c, with serial cable. All I get is:

Turn on empeg unit now
found empeg unit: entering program mode
Couldn't find manufacturer ID!

Looking at download.c I can see the comment:
Look for '#' then 4 hex digits
I guess I don't get those digits. The output of my bootlog ends like this:
kftpd: listening on port 21
player.cpp : 385:empeg-car 2.00-beta11 2002/02/08.
Prolux 4 empeg car - 2.1434 Feb 7 2002
Vcb: 0x4086d000
! mp3_decoder.cpp : 1049:Failed to find valid sync after seeking to offset 3862714, error=0xc0044000

And there is no '#' followed by 4 hex digits.
Am I right that the log file is incomplete? What could be the cause? Could it be an error in the flash memory? I do not get a shell, the console just dies... Will I be able do force a new kernel upload?
