Part Number: AM6442
Other Parts Discussed in Thread: UNIFLASH
Hi TI Team,
We are working on a custom AM6442 board using Processor SDK Linux 9.x and would like to boot completely from OSPI flash without using an SD card.
We plan to flash the following images using UART UniFlash:
* tiboot3.bin
* tispl.bin
* u-boot.img
* k3-am642-evm.dtb
* am6-sdk-tiny-fs.ubi
We would like clarification on the following points:
1. Does UART UniFlash support directly flashing a UBIFS image (root.ubifs) to a UBI volume, or does it only support flashing a UBI image (root.ubi)?
2. If root.ubifs is supported, how are the UBI volume creation and UBI attach operations handled during flashing?
3. Is it recommended to generate and flash a root.ubi image instead of root.ubifs for production programming?
4. Could you provide an example UART UniFlash configuration file for flashing the above images to OSPI flash?
5. After flashing, what are the required bootargs and partition settings to ensure the kernel automatically attaches the UBI partition and mounts the UBIFS root filesystem?
Any guidance or reference documentation would be appreciated.
Thanks,
Ganesh D
