Compilation fails, no rules for NV fw

[grepwood]

When executing make O=build/hac-001/ -j4 Image, at some point the compilation process will print

make[2]: * No rule to make target 'extra_firmware/nvidia/tegra210/vic04_ucode.bin', needed by 'firmware/nvidia/tegra210/vic04_ucode.bin.gen.o'.  Stop.
make[2]: * Waiting for unfinished jobs....
  MK_FW   firmware/nvidia/tegra210/vic04_ucode.bin.gen.S
make[1]: * [/usr/src/linux-next/Makefile:1018: firmware] Error 2
make[1]: * Waiting for unfinished jobs....

and when all else is finished, it will just print error 2.

Did you follow this steps in the instructions? Download the linux-firmware package from here mkdir extra_firmware Copy nvidia/tegra210/vic04_ucode.bin and nvidia/tegra210/xusb.bin from the package to linux-

[grepwood]

Yes. I've taken the liberty to instead install the package from Gentoo, as it is my distro of choice and it provides the package. Is the following correct?

localhost /usr/src/linux-next # mkdir extra_firmware
localhost /usr/src/linux-next # cp /lib/firmware/nvidia/tegra210/* extra_firmware/

And yes, the directory /lib/firmware/nvidia/tegra210 contains the files we're after.

edit The instructions do not say WHERE to copy the firmware files or in what way. Should we also re-create the nvidia/tegra210 catalogs?

i think you are sending it to the wrong destination folder. you are sending to. cp tegra210/* extra_firmware/ instead of cp tegra210/* extra_firmware/nvidia/tegra210/

[grepwood]

Yeah, definitely wrong. I looked at the patch code and now it builds. The instructions should say something along the lines of

mkdir -p extra_firmware/nvidia
cp -rf /lib/firmware/nvidia/tegra210 extra_firmware/nvidia

It's way easier to understand than

mkdir extra_firmware
cp foo/bar/foo extra_firmware/dir_that_doesnt_exist
cp bar/foo/foo extra_firmware/dir_that_doesnt_exist
cp foo/foo/bar extra_firmware/dir_that_doesnt_exist
