I've recently purchased a Sipeed Maix Bit, which is based on the Kendryte K210 (RV64GC dual-core), just so that I can start messing around in the RISC-V 64-bit ecosystem. However, the K210 has just 8MB of on-chip RAM, limiting the applications. It ships with MicroPython, and you can run microcontroller Linux, which is a fun little hack.
However, I'm primarily interested in Rust development on the RISC-V. For bare-metal programming, the K210 is enough for me to get my feet wet. Thanks to the wonderful community, you can already run gdb for source-level debugging of Rust on that platform, with the addition of a $7 USD JTAG adapter.
That said, as long as the PicoRio board (even without a GPU) is available for less than $100 USD, I am totally buying one as soon as they are available for order.
