Re: [microblaze-uclinux] SystemACE mount on S3MB1500 fails

[Claudio Lanconelli <lanconelli.claudio@xxxxxxxxx>]

Hi Marco,
I used systemace several months ago, so I'm not sure but I think to
remember that you
have to configure the FPGA from the systemace file in the compact flash
in order to
access the compact flash from ucLinux. If we are talking about Memec
3S1500 evaboard
I had problems with reset, so I had to keep the FPGA reset pushed during
systemace
configuration (AC25 on the board reset, not systemace reset!).
After that you should mount the compact flash successfully, I suggest
you to start
mounting the card read-only. If the system hangs when you mount the card
read-write
try a patch I posted some months ago on this list.

Cheers,
Claudio Lanconelli
