The SDIO controller can send CMD13 during card programming mode to check the card status. If software sends an R1b response type command (e.g., CMD38, CMD6) followed by a CMD13 (status check), the controller sends the transfer complete before completing busy due to the CMD13 status check.
This can be avoided by not sending a CMD13 immediately after sending an R1b command (e.g., CMD38, CMD6 etc.).
Impact: | Minor, refer to the Work-around. |
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: | Avoid sending CMD13 after sending R1b commands (e.g., CMD38, CMD6, etc.). |
