Hi
I tried to build for my custom board , I had one driver with an sysfs entry and I tried another sysfs entry in another driver. When I tried to make both drivers as LKM I’m getting this error
`Linux_for_Tegra/source/public/kernel/kernel-4.9/Makefile:1085: vmlinux] Error 1

make[1]: Leaving directory Linux_for_Tegra/source/public/kernel/kernel-4.9/kernel_out' make: *** [Makefile:171: sub-make] Error 2

I can’t answer this specifically, especially since not enough information is present. However, I’ll start with the most obvious questions:

  • Is this the kernel source from a specific L4T release?
  • Did you start with configuration target “tegra_defconfig”?
  • Were any edits to configuration using a dependency-aware editor, e.g., menuconfig or nconfig?
  • Is this a cross compile on a host PC using cross tools, or is this natively compiled?
  • Related to the prior question, if cross-compiled, what compiler version was used? Is that something you’ve checked as compatible with that release?
