Part Number: SK-AM64B

Tool/software:

Hi All,

I want to start all files, including the kernel and root file system, from O-SPI, but it does not start successfully.

[Question]
Are there any manuals or other instructions for starting all files from the O-SPI?

Best Regards,

Hi Ito-san,

there are steps in a different thread that show how to program U-Boot into OSPI and package the rootfs into an UBIFS image and program it and then boot everything from OSPI, see https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1018036/am6442-how-to-create-ospi-rootfs-ubifs-and-boot-linux-from-ospi-without-sd

The steps are however for an older SDK. I'm working right now to re-create / re-fresh those steps as needed specifically for SDK v11.x and will post those here shortly.

Regards, Andreas

I have this fully working now, running a Linux rootfs out of OSPI using UBI/UBIFS on SK-AM64B in the context of SDK v11. It was a little more involving than I thought... I'm compiling and cleaning up the steps currently, and will post this as a solution here tomorrow.
