Hello,
For a project I would need to record I2S MEMS microphones data into a SD card to analyse it offline.
For now I encounter some issues with the SD card.
I'm using the T4 and an audio schield, just to do the tests I will then solder a SD port directly on the T4.
My SD cards are a Samsung EVO Plus U1 and a SanDisk Extreme PLUS U3. Both are 32GB SDHC.
I just ran exemple sketchs like the CardInfo with the SD.h library and the SdInfo with the SdFat library. I just set the chip select to 10.
With both libraries the Samsung Card is not detected and the SanDisk is detected but not usable. For example in the SD.h CardInfo example I get "Could not find FAT16/FAT32 partition.Make sure you've formatted the card".
Of course I formatted and refformated the card to a FAT32 partition.
My best guess for now is that these SD cards are not compatible but I find it strange therefore I would like to have confirmation before ordering a new one.
Thanks,
Vuhian
