[saiff]

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,

Hi,

 

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

Does the nRF7002-EK LED light up?

 

Kind regards,

Håkon

i just got a new nrf7002ek and now it's working fine, apparently the first one i got was damaged

Thank you for your help

kind regard,

[Håkon Alseth]

Sorry to hear that the first one was damaged, but I'm glad to hear that you got it running now.

 

Hope you have a wonderful day!

 

Kind regards,

Håkon

hi 

Now it occurs the same situation to me .
I think there might be a problem with my wiring.

Can you tell me how you connected the nrf52840DK with the nrf7002EK?

Thanks.

Hi,

 

See here on how to physically connect the nRF7002-EK to a development kit:

https://docs.nordicsemi.com/bundle/ug_nrf7002_ek/page/UG/nrf7002_EK/intro.html

 

If you still have issues, please create a dedicated thread with logs 

 

Kind regards,

Håkon
