I bought five 32GB microSDHC UHS-I Sandisk and they fail to be recognised.
Formatting with other cluster sizes did not help.
A Sandisk 16GB Ultra works fine .
The difference between the 2 cards is the print on the card.
The 32Gb card has A1 printed below 32GB and the 16 GB card not.
I just found out I get this message after uploading a simple program writing "hello" to the card:
E (1697) sdmmc_common: sdmmc_init_ocr: send_op_cond (1) returned 0x107
E (1697) vfs_fat_sdmmc: sdmmc_card_init failed (0x107).
E (1709) gpio: gpio_install_isr_service(449): GPIO isr service already installed
and from my program: SDCard not Mounted!
See this INO file
SDCard-error0x107.zip
I compile with these settings. Pocuter libraries in sketch folder in folder 'libraries'
