  I have successfully built the buildroot firmware and it works well. I then used the kernel config tool to add modules for usb serial devices. The build produces the following output:
  

  Code: Select all

  make: Entering directory '/home/andy/Lyra-sdk/kernel-6.1'
    SYNC    include/config/auto.conf.cmd

    Image:  zboot.img (with zImage  resource.img) is ready
  make: Leaving directory '/home/andy/Lyra-sdk/kernel-6.1'

  This all looks fine but when I burn the generated firmware these modules are not present (not shown by lsmod.) What do I have to do to add them to the kernel properly?

How long does it take you to build a Buildroot image? I've been running the build command for 18 hours, but it seems like it will still take a long time to complete.
