ls1021a-iot booting from SPI

[renaud]

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

Did you achieve LS1021A-IOT booting from QSPI? I am trying but with no result

[renaud]

yes. On the LS1021A-IOT booting barebox.

Could you help me how to do it? I am really struggling but I did not achieve any result.

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.

found this https://source.codeaurora.org/external/qoriq/qoriq-components/u-boot/tree/board/freescale/ls1021aiot... but I would need the RCW source to enable SPI.

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