I use esp32 poe from olimax
( ESP32-POE IOT DEVELOPMENT BOARD WITH 100MB ETHERNET, POWER OVER ETHERNET, WIFI, BLE, PROGRAMMER )
I have used SD card with ETH on SPI port and Sometime it show "sdmmc_common: sdmmc_init_ocr: send_op_cond (1) returned 0x107" then, my SD card will not come back again.

The problem is I use SPI port with several IC including with 2 MAX31850, 1 MCP32S08 and SD Card
when I have to read input from MCP32S08 I have to end SPI by SPI.end() and Begin MCP32S08 again for reading data and when I finished the process I have always SPI.end() every time
   
How can I protect
"sdmmc_common: sdmmc_init_ocr: send_op_cond (1) returned 0x107"

Please Help ;D

Thank you so much
