Okay, that's good to know. I didn't go look at the spec yet and was going by the scant information that I've found so far. I'd like to know if there is any way to specify the maximum number of partition entries in the partition table header so that partitioning tools don't blithely overwrite the firmware image. That said, sharing an eMMC as both the boot device and a general purpose disk is a support nightmare for real products. Some users will almost definitely end up bricking the thing by reformatting the eMMC. I don't think that is a usecase that we want to spend a lot of time trying to support. > Is the hardcoded LBA 17 an eMMC specification thing?

That's how that particular SoC want's to use an eMMC or an SD card for loading firmware. g. ------------------------------------------------------------------------------ Everyone hates slow websites.
