I’ve seen the copy to eMMC script in root and tried that. After running it, i checked the MSDOS and UFS partitions and it seems they are OK. But, after removing the SD card and trying to boot from the internal eMMC i just see „C“’s coming out slowly of the serial console, nothing else is happening. Putting in the SD card and all runs well again. I tried this today with one of my BBBs, and I see the same thing. Clearly, the ROM does not like either the MBR partitioning or the MSDOS format being used by FreeBSD. The copy-to-emmc.sh script did work at one time, so I suspect something has changed in FreeBSD since then. > GEOM_PART: integrity check failed (mmcsd1, MBR) > GEOM_PART: integrity check failed (diskid/DISK-5F817AAF, MBR) If I format the eMMC then boot from SD, I see the same messages here, so I don’t think you have a defective eMMC. I suspect a fatal mismatch in the CHS geometry assumptions somewhere. Timhome | help
