U-boot MMC: 0 busy timeout

Hi,

Based on the custom Zynq UltraScale+ MPSoC board, I have a problem in u-boot (xilinx-v2019.1).

I use QSPI boot, and when I try to access sd card through mmc command in u-boot command line, I saw below timeout errors.

ZynqMP > ls mmc 0
sdhci_send_command: MMC: 0 busy timeout increasing to: 200 ms. sdhci_send_command: MMC: 0 busy timeout increasing to: 400 ms. sdhci_send_command: MMC: 0 busy timeout increasing to: 800 ms. sdhci_send_command: MMC: 0 busy timeout increasing to: 1600 ms. sdhci_send_command: MMC: 0 busy timeout increasing to: 3200 ms.
sdhci_send_command: MMC: 0 busy timeout.
sdhci_send_command: MMC: 0 busy timeout.

I have already use the patch file which provides by this forum.

https://forums.xilinx.com/t5/Embedded-Linux/sdhci-send-command-MMC-1-busy-timeout-increasing-to-400-ms/m-p/1010277#M35986

Is there any solution to solve this?

Thanks.
