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.
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 SoC Silicon Revision Differences. |
Work-around: | Do not send a CMD13 when bus testing is in progress. |
