Linux device driver for nRF7002

Hi,

I'd like to evaluate Linux device driver for nRF7002; refer to 315431, I'd found this requirement had been reported one and half year ago; based on 315431, I have a few further questions:
c1. how to download the image of Ubuntu 22.04.3 LTS server variant (native to RPi4)? The hyperlink is disappeared; could you please provide a archived for downloading?
c2. is there a way to purchase the interposer board (i.e. RPi4B_interposer, PCA64167)? Or, have I to manufacture it using the Gerber file on Github repo?
c3. how to assembly nRF7002-DK, PCA64167, and Raspberry Pi 4 SBC? Is there a picture/photo for reference?

Thanks.

  • Hi Håkon,

    c1a.

    Ubuntu 22.04.5 LTS is different from Ubuntu 22.04.3 LTS on kernel. You may refer to the following paragraph or this link.

    Ubuntu 22.04 LTS initially shipped with the old Linux 5.15 LTS kernel series. The new Linux 6.5, set to be the foundation for Ubuntu 22.04.4 LTS, facilitates smoother installations on contemporary hardware, providing an optimal experience for those adopting the long-term supported Jammy Jellyfish series on new computers.

    Linux device driver does depend on the kernel version, it means the exact Ubuntu 22.04.3 LTS would be needed, and it would be the statement emphasized in ReadMe file.

    Ubuntu 22.04.03 LTS (64-bit) comes with 5.15.0-1037-raspi Linux kernel

    So, this is why I said that the archived file of Ubuntu 22.04.3 LTS is needed, especially such version is no longer existing on Ubuntu official web site.

    p.s. of course, suppose the device driver could be built under new kernel, it's fine.

    Thanks.
