[microblaze-uclinux] Systemace driver problems

[Claudio Lanconelli <lanconelli.claudio@xxxxxxxxx>]

Hi,
I have the spartan3 MB1500 Memec board with optional systemace board 
installed.
If I download the bitstream with jtag table the systemace driver fails without
print any error code, so I modified the adapter.c to report the error. 

The error was XSA_ER_CFG_READ: "JTAG controller couldn't read configuration 
from the CompactFlash". I can't understand why linux driver check for the
configuration file, however after hours trying anything I finally close the 
JP2 jumper on the systemace board (MODE jumper) and Linux finally print

Partition check:
 xsysacea: xsysacea0
System ACE at 0xFFFE0000 mapped to 0xFFFE0000, irq=2, 125440KB

Howerver at boot prompt when I tried to mount the device I got the same error 
again:
# mount -t vfat /dev/xsysacea0 /mnt
JTAG controller couldn't read configuration from the CompactFlash

Is there someone who solved this problem??

Regards,
Claudio Lanconelli

Here is the diff to uClinux-2.4.x/drivers/block/xilinx_sysace/adapter.c to 
print the error message:
