sdc erase handling of sdhc sdxc card
Posted: Sun Jan 28, 2024 10:34 am
Hi,
sdcErase fails for high capacity SD card.
from https://chlazza.nfshost.com/sdcardinfo.html, note 10 => 10. SDSC Card (CCS=0) uses byte unit address and SDHC and SDXC Cards (CCS=1) use block unit address (512 bytes unit).
So the test in sdcErase seems inverted
tested with if ((sdcp->cardmode & SDC_MODE_HIGH_CAPACITY) == 0U)
and it works !
when the following patch is applied, sdcErase works for sdhc card.
