Hi
I'm using almost the standard 8xxrom bootloader on my ADS860 board.
When I cross compile it on my I386 Linux host using the egcs-2.91, it works ok.
When I cross compile it on my I386 Linux host using the gcc 2.95.2, it doesn't work.
That means, it always crashes like:
-----
8xxROM 0.3.0
compiletime options:

disk: DISK_ATA PCMCIABUG
cpu: XPC860xxZPnnA3 at 25 MHz: 4Kbyte icache 4Kbyte dcache

board: ADS rev A - warning, read errata

Did someone encounter the same problem??
Maybe the gcc 2.95 does some better optimisations!
