LS1021AIOT - Yocto/OpenIL/RTE/OpenWRT Booting from QSPI

[Kensou]

Hello everybody, I am trying to implement on of Linux options (such as Yocto/OpenIL/Real Time Edge/OpenWRT)  in LS1021A-IOT Boards.

Unfortunately, it seems that none of these implement booting from QSPI Nor in LS1021A-IOT boards (LS1021A-TWR, which QSPI boot is supported, seems to be unavailable anywhere).

Is there a simple way for having at least uboot with spl from QSPI in LS1021A-IOT?

Thank you in advance

In u-boot source code, configs/ls1021aiot_qspi_defconfig is provided, please build image with this configuration.

With ls1021aiot_qspi_defconfig i am able to generate uboot-spl.bin or I have to change RCW too?

You need to generate separate RCW booting from QSPI.

Is there a tutorial, or did someone already make the RCW for the LS1021AIOT board?

You could use CodeWarrior QCVS tool to assist you to generate RCW booting from QSPI.
