Question

I have a Ti Sitara AM335x Starter Kit and I want to use USB 3G-Modem on it. I am following these documents:

http://processors.wiki.ti.com/index.php/Android-USB-3G-Modem-Integration & http://processors.wiki.ti.com/index.php/TI-Android-JB-4.1.2-DevKit-4.0.1_DeveloperGuide#Build_Procedure

I didn't get sources via repo. I used Pre-packaged. I can't build android linux kernel and get this error after this command

$ make ARCH=arm CROSS_COMPILE=arm-eabi- uImage

I have tried many things, including changing pm-firmware.bin to pm-firmware.bin.gen.o, Download ready kernel uImage and try to continue steps.

How could I fix this error?

Answer 1

Surprised no one answered this.

From here:

http://elinux.org/Building_BBB_Kernel

Do this from above your kernel source folder:

wget http://arago-project.org/git/projects/?p=am33x-cm3.git\;a=blob_plain\;f=bin/am335x-pm-firmware.bin\;hb=HEAD -O kernel/firmware/am335x-pm-firmware.bin

-J

Answer 2

The file was presumably in the kernel source tree when the kernel was built, and was linked into the kernel image. That's why you don't see it in a distro filesystem.

The file is also not a part of official Linux firmwares, so you have to get it outside as described above.

If you don't want to use it for some reason, you can disable this setting in your .config file: CONFIG_EXTRA_FIRMWARE="am335x-pm-firmware.bin" -> CONFIG_EXTRA_FIRMWARE is not set
