Hello,
I'm porting ecos to a custom board based on the Atmel EB55 board (with an
ARM7TDMI, AT91M55800A). It has the same RAM, but a bigger flash, and an
8-bit boot EEPROM.
My template in the configtool is nearly the same as the EB55 one, and also
the redboot_rom.ecm file is nearly the same, except for the other type of
flash (spansion S29GL512N).
RedBoot runs on the board (in ROM), and I can read/write RAM and flash,
and read the EEPROM.
When I want to load a file from PC to RAM, it fails after a couple of
retries. It never starts sending (no throughput, 0K sent). Last error is
'Unrequested response'.
I first give the command (below) in redboot, and then in hyperterminal I
select 'Transfer - Send file', protocol: Ymodem, I browse for the file,
and click 'Send'.
If I cancel the hyperterminal send, redboot is stuck (need to reset). If I
let hyperterminal retry until it gives up, redboot behaves sometimes
strange (see the 'x -b 0x0100F000' command). After a version command,
redboot is OK again (see same command lower).
Also xmodem fails.
Anybody any clue about what's wrong?
Thanks,
Juergen
