I'm the maintainer of a standalone printf library, targeting mostly embedded devices and other no-standard-library use cases: https://github.com/eyalroz/printf/ I would like to make sure the library can be used on this SoC, and other RISC-V systems; which it probably can, but if there are any issues cross-compiling for it, or using the toolchain Espressif provides, please consider filing a bug report on GitHub at the link above. Same of course goes for any FOSS librar/tool that you're trying out. Let's help foster a rich(er) ecosystem of software available on these babies!
