J7200XSOMXEVM: Booting blank board over BOOTP

Part Number: J7200XSOMXEVM
Other Parts Discussed in Thread: DRA821

Hi,

The boot configuration for j7200SOM(DRA821) supports BOOTP and/or TFTP, but I could not find information how to set EVM switches (SW8&SW9) to configure it, how this would be possible?

The discussion here in the forum is a bit confusing, while someone claims to have loaded tiboot3.bin over BOOTP they were not able to load tispl.bin, is still an issue in the latest SDK?

Br.

    Hi,

    Ethernet boot mode is not supported.
    But, you can use other boot mode and boot till u-boot, from u-boot you can use tftp. Please refer to Linux SDK Documentation for more details.

    Hello Sudheer,

    Thank you for a quick answer!

    Is the limitation due j7200-EVM board or the j7200-SOM itself? i.e. would it be possible to boot from the ethernet with a custom board?

    If the limitation is due the SOM itself, is it in the boot ROM code, or would it be possible to circumvent by customizing the R5F SPL (tiboot3.bin)? Since an earlier discussion here seems to indicate the ROM code will load tiboot3 over the ethernet.

    Best Regards

    Hi Juha,

    SOM itself has some Errata related to MDIO, that's where we are not claiming support for Ethernet Boot mode.

    As per internal discussion ROM code supports boot from Ethernet, but we not have software support for the same i.e. tiboot3.bin passing via Ethernet.
    Also, as per above it is not recommended for Production support.

    So, please use other boot modes.
