[ECOS] eCos gdb-stub problem (on SA1100)

[Andreas Bürgel <ab at genologic dot de>]

While trying to track down my application-problem I got the current
CVS-source-tree and made a new gdb-stub. Before I used a gdb-stub
compiled with two(?) month old cvs-tree and a current cvs tree for
application development.
I can connect to the stub with gdb, but download fails after some
hundred bytes. I get the .rom_vectors segment transferred, but after
transferring approx. 1220 bytes of the .text segment I get packet errors
and the transfer hangs. The hardware hangs and shows the same symptoms
as in my other posting today - my debug LED is on and stays on. At this
time of the download, only the stub code contains LED interaction (some
blinking).
I'm quite sure I didn't change very spectacular things in my
stub/startup code, so why does it work with a two month old eCos-tree
but not with the current?

Thanks for any help.

(Andy, the hardware settings of the board's RAM are very conservative
currently and proved working.)
