cr1901_modernmithro: "PackagesNotFoundError: The following packages are not available from current channels: gcc-riscv32-unknown-elf-newlib"05:45
cr1901_modernhmmm wait05:45
mithrohttps://anaconda.org/TimVideos/gcc-riscv32-elf-newlib05:47
cr1901_modernthat worked, but the build-micropython script is bugged05:52
cr1901_modernmithro: There needs to be a gate in the Makefile for riscv vs riscv-unknown05:56
cr1901_modernthe freestanding compilers use the latter05:57
cr1901_modernThe one w/ newlib uses the former05:57
cr1901_modernmithro: Okay, compiling micropython w/ riscv leads to all sorts of errors that aren't present on the lm32 version. They appear to be of 3 different classes:06:30
cr1901_modern1. RV32I needs libcompiler_rt linked in to provide mul, div, and friends.06:30
cr1901_modern2. The linker is complaining that start is multiply defined (need nostartfiles/nostdlib? For some reason lm32 doesn't need this)06:30
cr1901_modern3. The linker is complaining that hard float modules are being compiled with soft float modules ._.06:30
cr1901_modernhttp://ix.io/1qlB Obligatory link06:33
cr1901_modernI'm breaking for tonight06:33
cr1901_modernActually... one more thing...06:34
cr1901_modernNope... nothing printed to the screen either06:36
cr1901_modernsimple stub firmware isn't working either. Looks like I have my work cut out for me :P06:37
cr1901_modernAhh well, need to rest for now06:37
mithroYou have done something wrong06:42
mithroAs we have micropython booting onnl RISCV on arty, right?06:42
