XIO2001: Hang on or abort when doing high speed continuous data transfer

Edward Lee

Part Number: XIO2001

Dear Team,

My customer encountered a problem with XIO2001.

Their system can find the device in the OS but will somehow it will hang on or abort when doing continuous data transfer.

The duration from the start of data transfer to system hanging on\abort varies. It may take several hours to one day.

Once the transfer is aborted, the system cannot find the device and must be cold booted to work properly.

They tried to dump the register of XIO2001 before and after abort below.

@ Default normal register

@ Abort and read the register again

Some registers are modified. For ex, the value of address 0x4 is modified from 0x07 to 0x00.

They have little idea what might cause this problem.

They also tried to use EVM to test in the same system and the same program. It ran normally with the XIO2001EVM.

Would you kindly give us some directions?

Thanks

Sincerely,

Edward

Hi Brian,

Thanks for your help.

Just want to add more information for the problem.

Once the hanging on/abort occurred, they can observe the PRST# is asserted low for around 50ms.

After that we can find the PCI configuration register below, the red marked one is changed.

From address 0x20~0x28, you may find the mem base point address of the add-in card is cleared (changed) compared to the figure in previous post.

If we re-write the normal value to these changed address, we can re-open the add-in card and run the program again.

But it still will abort/hang-on after several hours.

Thanks for your support.

Sincerely,

Edward
