<seds> I am having some problems with the compiled crosstool-ng for RISC-V. I keep getting Error: unrecognized opcode `csrw mtvec,x10' when compiling with the built gcc. Any idea what am I missing?
<seds> I've also compiled riscv's gcc toolchain, but I got the same result
<la_mettrie> just a guess, but makes me think if the instruction extension containing csrw is in use
<seds> hmm, well, I am compiling this against the neorv32 soc, using their hello world example
<seds> it should work, at least it did a few weeks ago
<seds> I am almost sure I am missing something on the compiler though
<seds> but then again, it is odd that two different riscv compilers gave that error
<seds> does gcc have any flags which outputs all the available opcodes?

<sorear> maybe related to the change recently to have rv32i no longer imply zicsr
<sorear> are you using march options?
<sorear> does tacking _zicsr on the end help?
<sorear> "available [mnemonics]" is a gas thing, not a gcc thing, and I'm not aware of any such flag, sorry

<coolbeans> oi, the community is growing indeed
<coolbeans> i haven't poked around here since hifive1 came out and i swoop'd a preorder
<coolbeans> my email got notification of some MangoPi-Nezha MQ in the pipeline... oi!
<coolbeans> pretty coolbeans to see such a benchmark
<coolbeans> what else is going on in the world of riscv
<coolbeans> anyone have a decent 64 out?
Teufelchen has joined #riscv
<la_mettrie> what is decent...

<coolbeans> la_mettrie: boots to an operating system
<coolbeans> i guess i didn't just mean a 64 chip, but a 64 board
<coolbeans> any riscv64 boards out there that can run a terminal?
<rm> LicheeRV is cheaper and more available and can handle running a terminal too :)
<rm> about $30 for the whole thing shipped

<qwestion> How do I follow libre toolchain developments , like, to design socs
<qwestion> Or cores at least

<la_mettrie> qwestion: gcc and other parts of the toolchain probably have their own e-mailing lists and channels
<la_mettrie> and hubs
<la_mettrie> *gits
<qwestion> GCC to design cores/socs? Reread my q
<muurkha> don't be rude to people just because they misunderstand you
<la_mettrie> ok, i usually think of software when somebody says toolchain
<qwestion> I've heard of betrusted using FPGA tools like yosys and co and that also isn't the toolchain I'm looking for...
<qwestion> muurkha: how can I word it less rude?
<[exa]> "libre toolchain developments" is literally a question for gcc mailing list :]
<[exa]> designing socs is I'd say a completely different problem, though related
<muurkha> [exa]: there's also a libre toolchain for designing socs (the yosys and co menttioned above)
<muurkha> qwestion: I read "reread my q" as being pretty rude; you could've said "I didn't mean that" or at greater length "I'm talking about HDL toolchains for synthesis and place & route"

<muurkha> what's obvious to one person often isn't obvious to another
<[exa]> ah these toolchains.
jmdaemon has joined #riscv
<qwestion> Got it, I'm on mobile and sometimes choose efficiency over unambiguous politeness
<sorear> we get mentioned somewhere?
<qwestion> ?
<qwestion> I think I will ask these (Free/Libre toolchain (Yosys/Trellis/Nextpnr)) projects as well as Ariana and alibaba's subsidiary's forum
<qwestion> 3rd RISC-V Meeting + OpenHW Day
<qwestion> https://open-src-soc.org› 2021-03 › program-riscv-meetings.html
<qwestion> 2nd RISC-V Week: 3rd RISC-V Meeting + OpenHW Day Two RISC-V events over 3 days! The program is online and registration is open! ... CPU, on top of Lattice ECP5 FPGAs programmable using a Free/Libre toolchain (Yosys/Trellis/Nextpnr)
<sorear> looks like a spike in new users on the channel, wondering if that was prompted by anything
<qwestion> I've been following for a while, but maybe fosdem?
<qwestion> They had open-hardware devrokom on matrix
