Buildroot: How to flash the eMMC on the BBB

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?


This is the kernel configuration


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.

Best Regards
