wififund_less3_exer1 build issue

[cfs]

I was working through the wifi course in dev academy. I'm having a hard time getting exercise 1 to build. Anyone else running into this? I'm building for nrf7002dk_nrf5340_cpuapp.

Hello Collin,

Could you check if you are having any issues building other default samples in NCS?

Regards,

Elfving

[cfs]

I just tried a lesson 2 sample that built without issue. And then a lesson 4 solution failed. I guess this may be on my end.

[cfs]

A colleague tried to build this application as well and got the same output as above.

[Elfving]

Sorry about the wait Collin,

I just wanted to make sure that you had no issues building a default sample earlier, because there's typically nothing wrong with just the fundamentals course. It would typically rather be something wrong with an installation etc.

Though I am seeing the same issue as you. And one other colleague of mine is seeing the same issue, though another is not. 

I find that I do manage to build it though, if I add these configurations to the prj.conf. Could you check if that fixes it on your side as well?

CONFIG_FLASH=y
CONFIG_FLASH_MAP=y
CONFIG_NVS=y
CONFIG_SETTINGS=y
CONFIG_SETTINGS_NVS=y

Thanks for reporting this, and sorry about not trying the sample myself immediately.

Regards,

Elfving

No problem at all, I appreciate you looking into this. I was not sure if it was my environment causing the issue or not. I think another wifi course exercise has issues too. I will get back to you once I test these again.

[Elfving]

Thanks, that would be great :) Good if you could also test if the configs I've provided also fixes anything for you.

Regards,

Elfving

I face the same problem. I tried to build the less3 exer 1 solution example, but I get the same error in the linking process:

I also tried to build another example in Exercise 2 of the Wifi Basics course and also got an error in building the code. So I think it has something to do with PSA and TF-M, because the exercise 2 example 1 is not trying to use TF-M, the rest of the examples are using TF-M.

Hi Aljosa,

I've gotten it working on my side. I think the path length could be a part of the problem, but I see that path length shouldn't be an issue on your side. C:/wifi-fund/lesson3/wififund_less3_exer1_solution is rather short. 

Though could you try placing the sample in C/wifi-fund/ and see if it makes a difference?

Regards,

Elfving
