I ran into the same problem. I tried to enable CMA by compiling Linux kernel but I couldn't get it.
I tried [this instruction](https://www.digikey.com/eewiki/display/linuxonarm/DE10-Nano+Kit#DE10NanoKit-LinuxKernel) and I enabled CMA in the kernel config. Then I booted with the kernel but `/dev/cma` doesn't exist. **Environment:** OS: Angstrom Linux (downloaded from Terasic's website) --- [Visit Topic](https://discuss.tvm.apache.org/t/vta-cma-settings-for-de10-nano/9696/2) to respond.
