AM2632: Enabling XIP for AM2632

Jo Scho
Intellectual 300 points
Part Number: AM2632


Tool/software:

Hello,

we are using AM2632 in our project, with extern al flash, via QSPI mode.

I have written my own SBL, based on SBL_QSPI-example from SDK.

Is it possible to use/enable XIP on AM2632? Is XIP supported by AM263x?
Background: we could place the hsmRtImage and pru-Images (included as header) to external flash, to save internal RAM).


Best regards
Jo

    AM263x does not support XIP.

    That can still be done, you can then copy these at run into ram and use them as needed.

    Can you give me some example? Can I find an example in the MCU_SDK?

    We want only one flash file, which contains RPRC multicore image and the other filkes (H-Files of PRU and HSM)...

    You saiy, load into RAM at run...can the load then be executed step by step...because otherwise I need the whole RAM again...

    That is not possible Jo, because app images are signed and are append with signature for ROM to authenticate.

    Also I would recommend moving to mcelf image s app-image will be depricated from next sdk release. It has faster boot time and better security features as compared to appimage

    The way I recommended was to flash these separately at different flash locations and then retrive it at runtime in the application.
