Hi Siva,
thank you for answering,
glad to have support from the Sysace producer ;-)

Seems all right here, but can you confirm how do I have to format the 
Compact Flash ?
I am doing
for 16MB CF
 mkdosfs -v -F 16 -R 1 -s 2 -n XLNX_XUP E:
for 128MB CF
 mkdosfs -v -F 16 -R 1 -s 8 -n XLNX_XUP E:
but I always have JTAG errors [1]

Exactly where should I perform such reset ?
which file and function ?
maybe in xsysace_intr.c ?

As you can read in my previous posts in this thread,
I am using a custom bootloader based on using xilfatfs standalone 
library, and it is the only SysACE working stuff.

[1]Once Linux has booted I no longer am able to use it due to puzzling 
JTAG errors.

A hint will be greatly appreciated
TIA
