I am sorry, I found a mistake on my part.
I fixed the code 'exactly' as you stated and I believe it is now working.
You are now in my credits page!
Extensive testing will now occur.
Thank you very much.

Subject: RE: XSysAce driver cant mount DOS part
Hi,
Thanks for your insight into the older code.
I tried your fix and came up with this.
I have run e2fsck and the cf card comes up clean with that.
heres a boot sequence:
Initializing Cryptographic API
io scheduler noop registered
io scheduler anticipatory registered (default)
io scheduler deadline registered
io scheduler cfq registered
Serial: 8250/16550 driver $Revision: 1.90 $ 4 ports, IRQ sharing disabled
serial8250.0: ttyS0 at MMIO 0x40421003 (irq = 4) is a 16550A
serial8250.0: ttyS1 at MMIO 0x40401003 (irq = 5) is a 16550A
RAMDISK driver initialized: 16 RAM disks of 65536K size 1024 blocksize
XSysAce driver v0771.
IDENTIFY: heads: 16, nsec: 63, cyls: 1011, size= 1019088
REGISTERED: major no.= 125 capacity= 1019088
xsa: xsa1 xsa2 xsa3
Uniform Multi-Platform E-IDE driver Revision: 7.00alpha2
ide: Assuming 50MHz system bus speed for PIO modes; override with idebus=xx
mice: PS/2 mouse device common for all mice
TCP bic registered
NET: Registered protocol family 1
VFS: Mounted root (ext2 filesystem) readonly.
Freeing unused kernel memory: 100k init
EXT2-fs error (device xsa2): ext2_check_page: bad entry in directory #32689:
unaligned directory entry - offset=1024, inode=1713398885, rec_len=29295,
name_len=109
Warning: unable to open an initial console.
init has generated signal 11 but has no handler for it
Kernel panic - not syncing: Attempted to kill init!
The only thing I notice is that the disk capacity is wrong, its a 512Mb, not a
1Gb as shown.
Any thoughts about what to look into next?
Thanks a lot.

Subject: Re: XSysAce driver cant mount DOS part
Hi Joe Robertson,
Thanks for the link.
In the xsa_thread function, can u try changing the hardcoded coded value
"2" to "xsa_cur_req->current_nr_sectors "
The actual code in the given link.
for(i = xsa_cur_req->current_nr_sectors; i > 0; i-=2){
+ xsa_device.req_done = 1;
+ while ((stat = cur_req(&SysAce, sector,
+ 2,
+ buffer)) == XST_DEVICE_BUSY)
+ xsa_short_delay();
Try changing it to ...
for(i = xsa_cur_req->current_nr_sectors; i > 0;
i-=xsa_cur_req->current_nr_sectors ){ xsa_device.req_done = 1;
while ((stat = cur_req(&SysAce, sector,
xsa_cur_req->current_nr_sectors ,
buffer)) == XST_DEVICE_BUSY)
xsa_short_delay();
Due to the hardcoded value, it gave problem while mounting but no issue
with fdisk. It mounts well but generated a kernel BUG. Tried changing
the value to '1' from '2' , fdisk crashed but mount is working well. So
removed the hardcode value and then placed the dynamic variable
xsa_cur_req->current_nr_sectors which is chosen by kernel. And now fdisk
and mount both are working fine.
Pl let me know the results in your setup.
Thanks
