BeagleBone Black does not boot from eMMC

Postby sftb » Wed Oct 02, 2019 6:03 pm

Hello,

i got a BeagleBone Black as a present and wanted to install Arch Linux on the eMMC memory.

I followed the instructions (https://archlinuxarm.org/platforms/armv ... bone-black), but if I remove the SD card so that the BeagleBone Black can boot from the eMMC, it doesn't work.

If I want to format the eMMC memory according to the instructions I get the following message

$this->bbcode_second_pass_code('', '
[root@alarm ~]# mkfs.ext4 /dev/mmcblk1
mke2fs 1.45.4 (23-Sep-2019)
/dev/mmcblk1 contains `DOS/MBR boot sector; partition 1 : ID=0x83, start-CHS (0x20,0,1), end-CHS (0xff,3,16), startsector 2048, 7550976 sectors, extended partition table (last)' data
Proceed anyway? (y,N)
')

The first time I confirmed the question "Proceed anyway?" with "y". I have the guess that there is a connection.

I have no problem with Arch Linux ARM booting from the microSD card.

did you do the $this->bbcode_second_pass_code('', 'fdisk') command?

If your BBB is the 2GB then it won't have much free space.

Just checked on my BBB. You need to use $this->bbcode_second_pass_code('', '/dev/mmcblk1p1') without the p1 you are referring to the full mmc.

Oh yes also check carefully you are using the right /dev/mmcblkX device, there will probably be two, one is the eMMC and on the sd card. So take care not to overwrite the one that has the operating system you are currently running in ....
