Hello,
I am trying to bring up the Zephyr on imxrt1060 with Murata module but on configuring sdio speed to SDR50 SDIO enumeration Fails by stating SD tunning failed.
Below is the error log:
[00:00:02.819,000] <dbg> usdhc: imx_usdhc_set_io: SDHC I/O: bus width 4, clock 400000Hz, card power ON, voltage 1.8V

[00:00:02.864,000] <err> sd: SD tuning failed: -11
on further debug found that USDHC_TransferNonBlocking is failing by returns kStatus_USDHC_ReTuningRequest
Can please help in solving this issue.
NOTE: I don't see any issue on configuring SDR12 and SDR25.
