    Hi Hogler,
    It seems that the issue you are facing is related to your firewall restricting pip from accessing internet. Hint: You need to probably use a proxy if you have a firewall.


    Thanks,

    Hi Shreyansh,

    ok, that was a good hint. But now I stick in the next step:

    Hi Holger,

    Could you please check if you observe the same issue if you comment this flash tuning command from in only_wifi_fw.cfg

    Best Regards,

    Meet.

    Hi Holger,

    Are you using a TI EVM or a custom board?

    Can you try once with the uniflash in the programming folder instead of secured_programing folder.

    Hi,

    I found the mistake. I have an older board.

    -> If you are using an older LP version - move to the <cc33xx_mcu_package>/tools/programming/

    Thanks, Regards Holger
