Hellooooooo i try to make a port (downstream) for the Realme C21Y rmx3263 but the compilatioon of the kernel fail with an error who is not explain in the wiki so i was wondering if someone knows something :

`Error: ../arch/arm64/boot/dts/sprd/ums512-w27v1.dts:1044.1-15 Label or path modem_dbg_log not found

The Device Tree (.dts) references something that is not defined.

Two options:

  • Define it
  • Comment it out (for now) and continue with the port

Also, gpio-brcmstb.c cannot be compiled. I assume it's a downstream driver. See if the kernel successfully compiles if you disable the option for it in the kernel config, probably has 'BRCMSTB' in it, perhaps something like CONFIG_GPIO_BRCRMSTB (I'm making this up, but should be similar).

You can always try to look for gpio-brcmstb on kernelconfig.io if it is a driver that is upstream. This should give you an explanation what this driver is and what the config option for it is.

    Not the APKBUILD file, that's the .dts file from the error.

    Could also be in one of the files that it includes (see #include something.dtsi at the beginning)

    Also, as Clippy says: Asking in the Nura chats can help, although chats have the risk of questions getting lost. I prefer using threads like here or a forum. It's also easier to search than a chat.
