ls1021a-iot booting from SPI

We have a ls1021A-iot eval board.

I would like to boot it from the SPI NOR. This means I need to change the RCW.

Looking in this git repository: https://source.codeaurora.org/external/qoriq/qoriq-components/rcw/tree/

there is no directory for the ls1021aiot. Where can I find the source? 

I see that s1021aqds/NNR_PSS_NN_60/rcw_1000_qspiboot.rcwhas support for QSPI. Could I use that for the ls1021a-iot?

 

Cheers,

Renaud

The only officially supported OpenIL boot source is SD card.

If you want to use QSPI boot, you need to modify files in RCW configuration ls1021aqds/NNR_PSS_NN_60/rcw_1000_qspiboot.rcw according to https://source.codeaurora.org/external/qoriq/qoriq-components/u-boot/tree/board/freescale/ls1021aiot...

Then generate QSPI RCW image for ls1021aiot.

I forgot to mention that our final product will boot from parallel NOR.
