Keeping POWER relevant in the open source world

At the other end of the scale, if anyone wants to play you can run a little openpower CPU on an FPGA with completely open source. https://github.com/antonblanchard/microwatt

It's capable of running Linux, some example docs are https://shenki.github.io/boot-linux-on-microwatt/ The toolchain consists of "apt install gcc-powerpc64le-linux-gnu" on Debian, no funny downloads. And if you want to target a Lattice ECP5 board even the FPGA tools are also all open, thanks to Yosys and friends.

All the openpower ISA spec PDFs are available for perusing on the openpower site.

Thanks for sharing. I've looked at getting a PowerPC dev board, but didn't find anything at a reasonable price. I never made the connection that microwatt plus and FPGA would get me there.

We've now got a walkthrough up for getting Microwatt going on an OrangeCrab ECP5 board. https://codeconstruct.com.au/docs/microwatt-orangecrab/
