Hello,

i've been trying to do some exercices from the devAcademy on my nrf52840 DK but when i tried doing the "lesson_2_exercice_1" this is the result i get :

    Hi,

     

    [00:00:11.209,075] <err> wifi_nrf: nrf_wifi_hal_fw_chk_boot: Boot_sig check faile d for RPU(0), Expected: 0x5A5A5A5A, Actual: 0x0

    This indicate that the firmware is unable to communicate with the nRF7002.

    Can you share how you build/configure? I assume you're using a nRF7002-EK mounted on the nRF52840-DK?

     

    Kind regards,

    Håkon

    Hi, thank you for your response,

    yes indeed i'm using a nrf7002ek with my nrf52840DK, attached are the build/config files and parameters i used.

    I also tried to build it adding the nrf7002.overlay and still got the same results.

    Kind regard,

    also when the "wifi scan" command finally executes this is the result i get

    Thanks for the configuration files.

    I tried your prj.conf in the "wififund_less2_exer1_solution" sample, and it ran as expected on my nRF52840-DK + nRF7002EK:

    [00:00:00.282,501] <inf> wifi_nrf_bus: SPIM spi@4002f000: freq = 8 MHz

    Tested it with both ncs v2.5.2 and ncs v2.6.0.

     

    Could you try the solution sample and see if this runs as expected on your side?

     

    Kind regards,

    Hello again, i still have the same problem, perhaps it's a hardware issue

    Hi,

     

    Could you share a picture of how you mounted the EK?

    Does the nRF7002-EK LED light up?

     

    Kind regards,

    Håkon
