I have a 54454 design using a Compact Flash card attached directly to the ATA lines. When the CF card is inserted when the board is powered up (i.e. hot swapped), approximately 1/3 of the time the CPU will freeze (and eventually resets due to the watchdog). If the board is reset with the card in place, the CF card works perfectly. Has anyone else seen any issues with this?
Any ideas? Has anyone else successfully designed a CF interface on the 54454? If so, can you hot wap the card? Anyone perhaps have similar experiences with normal ATA devices (i.e. hot swapable HDs)?
Thanks,
Chris

Please provide me the schematic of CF to ATA converter if you have sucessfully sorted out the problem. I require this for my design.
