Zynq-7000 AP SoC, SDIO - CMD13 Not Handled Properly When CMD19 Is In Progress

Description

If the software driver issues CMD13 to read the card bus when a CMD19 bus-test transaction is in progress on the bus, then the interface controller is affected by the CMD13 waiting for CRC status on the bus-test data.

This can be avoided by not sending a CMD13 when bus testing is in progress.

Solution

Impact:

Minor

Configuration Affected:

Systems that use the SDIO controller.

Device Revision(s) Affected:

All, no plan to fix. Refer to (Xilinx Answer 47916) - Zynq-7000 AP SoC Silicon Revision Differences.

Work-around:

Do not send a CMD13 when bus testing is in progress.
