Tool/software: Linux
Hi!
We're working with OMAPL138-LCDK board. I'm trying to compile and boot the latest available Linux kernel (4.9.x) from the Processor SDK v03.03.00.04.
The default config I use is tisdk_omapl138-lcdk_defconfig. The toolchain is the latest GCC for ARM installed from the Ubuntu repos.
Everything compiles fine, no errors. But when I try to boot the Linux from the built binaries, it crashes. Boot log is as follows (user_debug=31 is specified in kernel args):

I tried to use the different config I found in the arch/arm/configs/ti_sdk_omapl138_release_defconfig. The same story: it crashes.
But when I use the pre-built binaries that I've got from TI along with the PDK, everything boots fine and works.
Could you please give a hint on how to compile the kernel to boot successfully?
