ls1028ardb rfs emmc fusing

pjw — Tue, 29 Sep 2020 07:13:20 GMT

I am using the ls1028ardb board.

succeeded in uploading kernel images using flex-build, tftp / code warrior.

Here's the question:
kernel img goes up to emmc, but rfs seem to go up to ram memory.
Because, when boot up the board, the files I created are reset.
So I want to put the RFS on emmc. If the root file system is uploaded to emmc, I think the file will not be erased.

I'm looking for related content in manual or flex-build guide, but it's hard to find.

I wonder if there is a similar content or a way to use flex-build or something. I want to know how to put the RFS on emmc using tftp or build boot.

Thank you!

You must be booting your board with TinyLinux userland which is ramdisk based. It does not matter where it is fetched from, the changes you made are lost due to the used filesystem type. Consider deploying Ubuntu userspace with flex-installer. This rootfs image is ext2-based and preserves your changes.Details can be found at the links below:
