SK-TDA4VM: How to switch the boot path in u-boot.img from SD card to ospi?

Cherry

You have already burnt the u-boot.img to ospi.

The failure message that you are seeing is because the Linux kernel and dtb is not present in the sd Card. Where is your rootfs present? We need either MMC sd or eMMC.

I want to do all boots from OSPI Flash only, now boot from Flash to uboot, subsequent Linux kernel and rootfs can't find the corresponding introduction and usable images

That is eMMC/SD not for OSPI.

Have you created UBIFS and that is failing for you? UBIFS is not supported in the SDK out of the box.
Do you have any other storage which can host the file system like eMMC?

Thanks Keerthy

I have an SD card that can be used to boot and can boot. I now want to start via ospi flash, so how do I create a proper UBIFS?Is there any documentation for this?

Hi Keerthy

I followed the link, but there were some problems。Boot to file system using SD card, I can perform mount ubifs, and then run reboot at command from kernel. In the uboot terminal my attempt to mount ubifs failed。

Then I tried to set up a direct boot after booting from ubi and showed an error similar:

Then i follow the link, boot after loading kernel images and dtb .The deadliest problem arises：

It seems that rootfs mount error, soft reboot according to the link can not maintain the mountable state of ubifs, soft reboot after re-entering the system ubifs is not mountable state, need to re-execute ubiattach:

So I think being able to keep ubifs after soft reboot should solve this problem. Or is there another way to fix the kenrnel startup error I encounter?

Cherry,

Thanks for trying. We will get back to you early next week.
