Latest RISC-V tools

[Ciaran Lappin]

Hi All, 

It has been a while since I was last playing with the risc-v toolschain. Am I right in thinking that the Rocket-chip (rocket-tools) repo is no longer being maintained, and that the I should be using the RISC-V Collab toolchain instead?

I am mainly playing debugging a verilator model of an RV32 using OpenOCD + GDB. 

Apologies if this has been asked a million times before. 

Thanks,

Ciaran

You can also check the xPack GNU RISC-V Embedded GCC:

https://github.com/riscv-collab/riscv-gnu-toolchain is probably the best bet for the latest toolchain if you want/need to build your own.

(Note that it's still awaiting updating to GCC 14 and the latest Binutils: https://github.com/riscv-collab/riscv-gnu-toolchain/pull/1472 - but you can build from out of tree/upstream sources of these if needed).

As Liviu mentions there is also the xPack binary builds: https://xpack.github.io/dev-tools/riscv-none-elf-gcc/

Another binary build option is the Embecosm builds: https://www.embecosm.com/resources/tool-chain-downloads/

There are probably other options too.

I should also have said that the latest bleeding edge RISC-V enabled OpenOCD sources are available from this repo:

https://github.com/riscv-collab/riscv-openocd/

Again Liviu has binary builds via his xPack project although I can't recall offhand if these are from upstream OpenOCD sources, the riscv-openocd repo sources, or a combination of both (plus other patches?)?

https://xpack.github.io/dev-tools/openocd/

Also - selected (non-multilib) binary builds of the toolchains are available from the riscv-gnu-toolchain CI GitHub jobs and these tools may suffice for some users' purposes:

Upstream, no custom patches.

Thanks for the clarification, Liviu.
