Help needed for "determine block for u-boot by using lsblk"

[sve]

A recent update on my PineBook showed this message: “determine block for u-boot by using lsblk” The u-boot file to be installed is this (I guess):
-rwxr-xr-x 1 root root 719708 14. Okt 13:23 /boot/u-boot-sunxi-with-spl-pinebook.bin

Here is the output from lsblk:

├─mmcblk0p1 179:1 0 213,6M 0 part /boot

Uboot needs to go on the block device, not the partition. So in your case either /dev/mmcblk0 or /dev/mmcblk2.

Thanks. mmcblk0 contains the currently used Manjaro (on a SD card), mmcblk2 seems to be an old Linux installation (probably on eMMC). Is dd if=<the-above-bin> of=/dev/mmcblk2 the way to go?

[Strit]

Use the commands it told you in the output when you updated the uboot package.

[sve]

Oh, yes. The message was gone; but I have found it in my /var/log/pacman.log. But what about the device: the eMMC device should be overwritten?

[Strit]

Depends on what install you want to set it for.

If for your Manjaro install, use the same device as the mounted partitions are on.
