ESP32 check sd format

[SyXavier]

Hi, Mr greiman. I configured SdFatConfig.h, but the serial port returns check sd format. The test case I used is unicodeFilename.

[greiman]

What is the SD format and how did you format it?

What is the output from the SdInfo example?

[SyXavier]

I use the windows disk tool to format the sd card to FAT32. The sd card can be read and written normally on the PC side.

SdFat version: 2.1.0-beta.3

Assuming the SD is the only SPI device.
Edit DISABLE_CS_PIN to disable an SPI device.

Assuming the SD chip select pin is: 5
Edit SD_CS_PIN to change the SD chip select pin.

MBR not valid, assuming Super Floppy format.

volumeBegin failed. Is the card formatted?

This card has a non-standard format. Try the SD formatter.

The card is very strange. PCs use the 4-bit SDIO protocol. The card may not work with SPI.

Edit: I suspect the problem is just the Format Windows used.

Thank you for your help, the problem is solved. I am grateful that you created this project to support unicode encoding.

@SyXavier please try to explain how did you solve it for others in the future

@uzi18 Use SD Formatter to format the SD card.
