Hi,
I had a ESP32-WROVER-IB (4MB) on my board 100% working with a SD card interface.
My PlatformIO(arduino framework) project has the SD card connected to the following pins:
// CS is connected to IO25 on Esp32. // Not typical IO5 as I require the CAN interface on IO5
// SCK is connected to IO18 on ...

Hi,
I just discovered the same issue. Worked perfectly on the 4MB version.
Were you able to resolve this?

Note - I'm using the ESP32-WROVER-IE(16MB) after upgrading from the ESP32-WROVER-IB (4MB)
Same SPI pins as above but with the SD_CS on IO25.

Thanks,
Neil.
