ESP32-WROVER-IB >> ESP32-WROVER-IE SD card issue on IO25

Postby NWElectronics » Mon Feb 14, 2022 3:54 am

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 Esp32.
// MOSI is connected to IO23 on Esp32.
// MISO is connected to IO19 on Esp32.

I needed more flash storage so upgraded to the ESP32-WROVER-IE(16MB). The SD card stopped working :(
The only difference I can see between the "ESP32-WROVER-IB" and the "ESP32-WROVER-IE" is the V3 chip.

I have another board that uses the ESP32-WROVER-IE(16MB) and it works with the SD_CS on IO5. So I know that the ESP32-WROVER-IE(16MB) works ok with the IO5 pin but doesn't work with the SD_CS set to IO25.

What has changed between ESP32-WROVER-IB(4MB) and the ESP32-WROVER-IE(16MB) with regard to IO25 ???

Thanks,
Neil.
