Adding an external flash memory "MX25R6435F" to my arduino nano 33 ble board

[gizgiz]

I want to use the external flash memory MX25R6435F to run my code which has a big size on my arduino nano 33 ble but I'am a newbie and I don't find supports that can help me,

Is that possible and should I add some configuration ?

Hello,

I don't see any external memory ICs on in the schematics: https://docs.rs-online.com/9208/A700000006519068.pdf. Have you connected it via the pin headers?

Best regards,

Vidar

Yes I want to use the pin headers to use the external flash memory MX25R6435F

I would recommend you consider the Edge impulse samples included in our nRF connect SDK instead of trying to integrate all this into a nRF5 SDK based project.

https://developer.nordicsemi.com/nRF_Connect_SDK/doc/2.0.0/nrf/applications/machine_learning/README.html

But I want my project to be independent of internet, and I made project with nRF5 SDK which require a long time

[Vidar Berg]

Internet access is only required when you need to train a machine learning model in the cloud, and that applies regardless of what SDK you use.

But in the prj.conf file we should put our model link

And i think that need internet connection

I also had this error when flashing:

C:\wrapper1\prj.conf:23: warning: ignoring malformed line '"'">studio.edgeimpulse.com/.../download

error: Aborting due to Kconfig warnings

CMake Error at C:\Users\ghaaz\ncs\v1.9.1\zephyr\cmake\kconfig.cmake:272 (message):
command failed with return code: 1

I also had a look at the questions posted in this forum, and I found that they couldn't work with this project and they advice them to integrate the model in their project:

The error indicates that you have a syntax error, but the screenshot doesn't show the whole line so I can't tell what it is. Do you get the same error if you revert back to the default URI?

You can find the description of what this symbol does here: https://developer.nordicsemi.com/nRF_Connect_SDK/doc/1.9.0/kconfig/CONFIG_EDGE_IMPULSE_URI.html
