How to enable compression with IMXpulpv2 #25

Closed desai35 closed 5 years ago

desai35 commented 5 years ago

Hi,

I built the ri5cy_gnu_toolchain using make and was able to run the IMXpulpv2 option . Is there any way to add the "c" option to enable compression with this option.

The standard riscv options like "rv32ic" come with the "c" to enable compression. WHen i try to add the "c" in the end of IMXpulpv2, it gives the following error:

cc1: error: -march=IMXpulpv2c: unsupported ISA substring c make: *** [../../wlan/src/mem_mgmt/mem_mgmt.o] Error 1

Thanks

The option is -mrvc. That's because this toolchain is quite old. You can use option -march=imcxpulpv2 if you switch to this toolchain: https://github.com/pulp-platform/pulp-riscv-gnu-toolchain
