Can I develop a project with SDHC card >4GB FatFs to works with STM32F107 with SPI?

I receive a commitment to upgrade one board from SD 2GB currently working, upgrade to SDHC that don't works. Project was released in 2012. Today custumer has difficult to find on market 2GB sdcard.

Is the latest HAL and FatFs for F107 works with SPI and SDHC?

Thank you

Maurizio

I believe the Adafruit SPI SDIO driver supports SDHC/SDXC cards, FatFs can support EXFAT if enabled in the build, but I'd recommend 0.13 over whatever ships with ST's middleware currently.

Might want to check the Adafruit code, had issue with multi-sector read/write I reported quite a while back.

You should test things.
