I was wondering about ARCv2 coverage in your build service. Do you have the needed
2nd toolchain for ARCv2 as well. If not can u add it please.

To build one, you could use upstream buildroot or the legacy scripts at

[email protected]:foss-for-synopsys-dwc-arc-processors/toolchain.git

Or if you so prefer, we also have prebuilt toolchains in github releases.

Thx,

Thanks for the information.

I created a toolchain using buildroot, and the build service already covers arcv2.
