MMC core reads SEC_COUNT information from EXT_CSD register and assumes that the card supports sector access mode. Some eMMC cards (<=2GB) do not support this mode even though they have SEC_COUNT value defined, causing failure while populating extended partitions. Sector/Byte access mode information is stored in OCR register. Hence, read OCR bit 30 and then confirm it with SEC_COUNT value to know whether the card supports sector access mode or byte access mode.
