Hi,
Issue overview
I'm trying to porting Cypress WICED WiFi Stack to MPC5748G from IMX RT platform. Other middleware like sdhc, freeRTOS, LwIP refer to MPC5748G driver examples in S32DS.
I encounter a SDIO CMD 53 timeout issue when do wwd_bus_sdio_download_firmware.
The enumrate of SDIO card and several CMD52 before download firmware work fine.
Things have try
1. slow down SDIO CLK
2. shorten fly-wire between MPC5748G and WiFi module.
3. 1 bit bus width and 4 bit bus width
4. try to send 1 block (size=64) every CMD53 and found that INT_STATUS has TC bit(transfer complete) and DCE bit(data CRC error).
And previous behavior in WWD driver is send 16 blocks (size=64) every CMD53, the corresponding result is INT_STATUS only has CC bit(command complete) ，ADMA_ERR_STATUS show data transfer error.
How can I resolve this? I can share more details if needed. Thanks.
Best Regards
Fearless
