General Discussion

Hi @Szymon_Kempny

In the step 7. Write sdcard.img to internal eMMC od BBB: dd if=sdcard.img of=/dev/mmcblk1
command just outputs:
0+0 records in
0+0 records out
I cannot write eMMC, how to make it writable?

Hi @mo_mq this was 2 year old thread…

please expand on what exactly (and with what versions) you where trying to flash…

First thought, do you have eMMC enabled or disabled?

Hi @RobertCNelson

Sorry, I don’t have the permission to create a new topic in this group.

These are the version I’m using
buildroot 2021.11 (beaglebone_defconfig)
u-boot 2021.04

I want to upgrade the MLO on eMMC, but I don’t know how to enable eMMC
This is the mmc devices printed on my board.
