Different postings seem to indicate different things.
I’ve been using u-boot for over a decade and I’m used to the saveenv/fw_* tools.
Seems the default beagles don’t support this. I have a older 2G eMMC and a newer 4G eMMC beagle – I just built uboot and that and the distributed one don’t have saveenv present.
The uboot I built was from the instructions here:
But this posting:
talks about fw_* tools and saveenv.
I’m slightly confused.
I THINK I have the same/similar question. Given the BeagleBone/BeagleBoard’s single ext4 partition strategy for containing the FS and kernel and where u-boot/MLO is copied into the the “hole” below the partition table using the dd command, where is the default and user-updated u-boot environment saved now?
I have an SD Card for the TI SDK for the 572xEVM which has 2 partitions, (1) boot and (2) rootfs. I believe in TI SDK land, the u-boot environment variables are saved to uboot.env in the boot partition… Thanks!!
Thanks Robert !
Looks like someone using yocto for BBB also had a similar question a couple years ago, https://lists.yoctoproject.org/pipermail/yocto/2015-April/024636.html…
