Enabling Wifi on nRF7002

I understand. Then I guess this ticket can be closed since the problem is solved.

Once again thank you very much for the help Amanda. All the best and have a great day! 😃

Please create a new support ticket for another issue.

You were right. I managed to produce both the ram and rom report!

I was missing the "./" when I previously tried running the command you mentioned. 🙂

Thank you very much Amanda!

Also, since we moved on to another part of the project, I've hit another issue. Can I ask here or shall I make a separate ticket?

Good to know you find the configs to reduce the image size.

As I explained, you executed the ram_report command for your application as: west build -d ./build/zephyr -t ram_report

Managed to make everything fit by minimising TFM:

CONFIG_TFM_PROFILE_TYPE_MINIMAL=y
# CONFIG_TFM_PROFILE_TYPE_NOT_SET=y

Resulting in a much smaller ROM footprint:

[quote user="Tudor B."]When building the rom_report using the command "west build -d build/mcuboot -t rom_report", but I get one of two errors.[/quote]

Do you build your application with mcuboot? Did you have the build/mcuboot folder? That command would analyze the RAM usage for mcuboot.

If you want to analyze your application, you should run

west build -d ./build/Your_App_Name -t ram_report

RE: Enabling Wifi on nRF7002

Edit:

I forgot to add that "add CONFIG_WIFI_CREDENTIALS=y in the prj.conf to fix the undefined reference to `net_mgmt_NET_REQUEST_WIFI_CONNECT_STORED'." worked like a charm! Thank you very much Amanda!
The overflowing ROM and RAM are the only things that remain.

Edit 2:
Is it possible to do a call so that we can quickly solve this issue?

RE: Enabling Wifi on nRF7002

Amanda Hsieh — Fri, 25 Apr 2025 19:08:50 GMT

You can refer to the Memory footprint optimization to reduce the size, and try to add CONFIG_WIFI_CREDENTIALS=y in the prj.conf to fix the undefined reference to `net_mgmt_NET_REQUEST_WIFI_CONNECT_STORED'.

RE: Enabling Wifi on nRF7002

Tudor B. — Fri, 25 Apr 2025 15:28:54 GMT

I managed to fix it by completely deleting my local git branch and getting the repo again from scratch, since I had the suspicion that installing the VS code extension changed some west files in my project. Everything is back to where it was. Meaning that I'm back to either having:

/Users/tudor/Documents/GitHub/micropython_nRF/ports/zephyr/../../ports/zephyr/network_wlan.c:165: undefined reference to `__device_dts_ord_135'

OR (when adding the sysbuild.conf):

Sadly, after trying to get the VS code extension to work, it completely broke the build via terminal. I get:

Is it possible to run "west update" under /opt/nordic/ncs/v2.9.1/nrf and delete the build folder to build again?

RE: Enabling Wifi on nRF7002

Tudor B. — Thu, 24 Apr 2025 17:16:14 GMT

Update: I tried installing the nrf connect extension for VS code. It brought a plethora of errors with it and I can't find a way of convincing it to work and build the project from inside it.

RE: Enabling Wifi on nRF7002

Tudor B. — Thu, 24 Apr 2025 14:46:31 GMT

1. Image size overload. You can refer to the Memory footprint optimization to reduce the size.

Our project is set up via terminal. Is there a way of generating the memory footprint without making the setup in VS code?

2. undefined reference to `net_mgmt_NET_REQUEST_WIFI_CONNECT_STORED' which is defined in the nrf/include/net/wifi_mgmt_ext.h. You can try to add "

The interesting part is that the file that generates the error has that include already put into place. Also, the network_wlan.c file that we're using to implement the wifi interface for micropython has the same include too. It's worth mentioning that both includes have no precompiler defines guarding them.

Hi,

Your log indicated two issues:

1. Image size overload. You can refer to the Memory footprint optimization to reduce the size.

2. undefined reference to `net_mgmt_NET_REQUEST_WIFI_CONNECT_STORED' which is defined in the nrf/include/net/wifi_mgmt_ext.h. You can try to add "

#include <net/wifi_mgmt_ext.h>" in the main.c

I'll see what I can disable to make things fit.

Edit:

I'm not sure what else to disable at this point since we already disabled the NFC and BT to make Wifi fit. Ideally we'd have all 3 active in the project. Here are our two .config files, maybe you can spot something that's a memory hog which shouldn't be there.

RE: Enabling Wifi on nRF7002

Amanda Hsieh — Tue, 22 Apr 2025 21:11:09 GMT

Hi,

Try to enable SB_CONFIG_WIFI_NRF70 in the sysbuild.conf as our wifi examples.

Regards,
Amanda H.

RE: Enabling Wifi on nRF7002

Tudor B. — Tue, 22 Apr 2025 09:41:38 GMT

A bit more trial and error was done that I'll document here. The initial suspicion about the default interface not being correctly initialised was on point.

The second error from the post ("undefined reference to `__device_dts_ord_135'") can be tracked down to the file "devicetree_generated.h", where I found:

*   135 /soc/peripheral@40000000/qspi@2b000/nrf7002@1/wlan

Looking over the various *.dts files, I found that the "zephyr_wifi" reference doesn't correctly link back to the .dts files that actually define it. Sadly I can't find a method of actually getting it to be correctly recognised.
