[srslte-users] epc error on Jetson TX2 aarch64 ARMv8 Processor

[Ralph A. Schmid, dk5ras]

I have run rsrLTE on the TX2 some time ago, and I needed to recompile the kernel to get some modules ePC requires. Mine runs Kernel 4.9, don't know if the Jetson distribution already got an update... In case you need more information I can look it up and let you know.

With best regards

Ralph.
