Re: [9fans] tinyemu - riscv emulator

Thanks for the lead. Checked Geoff Collyer's web site and the release of the Plan9 kernels for RISC-V are imminent. I'll wait for Geoff to release the new kernels. In the meantime I have some low-level programming work with your compiler and tinyemu running

Re: [9fans] tinyemu - riscv emulator

Thank you for the nudges towards the right direction. Self-inflicted confusion : I'm running 9vx and forgot that I was mk'ing an emulator to run within an emulator. After a lot of fiddling with libraries, dependencies I got tinyemu to compile and run. When I execute: tinyemu bridge.cfg It

> The make command failed with dependency on slirp module. I don't think plan 9 has a 'make' command. If you just run 'mk' on plan 9 in the tinyemu directory, it uses the mkfile there and there's no slirp dependency. -- 9fans: 9fans Permalink:

Re: [9fans] tinyemu - riscv emulator

The make command failed with dependency on slirp module. The download from Fabrice's website included slirp and the make ran to completion. My *real unsolved issue* is that I don't understand how to create a version of Plan9 that boots and runs on tinyemu. I confirmed that tinyemu itself runs

Re: [9fans] tinyemu - riscv emulator

I had difficulty in getting tinyEmu from contrib/miller/tinyemu.tar working. So I downloaded from Fabrice Bellard's web site and finally got it running the Linux that is referenced on his web site. I also have Richard Miller's RISC-V compiler compiled under x386 Plan9. BUT ... I can't find
