How can I customize eMMC partition layout ?

[mishuk]

ST provides eMMC partitions (besides fsbl and u-boot) : boot, root, vendor, user.

I need new partition /home and want removing vendor partition.

How can I get this customization ?

Hi @mishuk​ ,

You need to update your flashlayout file (*.tsv)

I would suggest to have a look into the wiki, the page STM32CubeProgrammer flashlayout could help.

Flashlayout file (*.tsv) is not a source file but is result of cooking Yocto recipes. My question was about proper Yocto recipes, but I have already done them by myself.

Haven't done it myself, but I guess the comments here are a good start:

@ST: A nice docu/wiki-article about adding a custom-board-layer with all kinds of changes (like changing partition layout) would be great *hint* *hint*...
