#RISCV #ESP32 #NuttX Here is a tutorial about preparing the environment and flashing NuttX with Arch Linux on a RISC-V EPS32-C3 based board
I discovered Apache #NuttX embedded #POSIX OS thanks to @lupyuen recent toots about NuttX on RISC-V based BL602 and BL604.
NuttX nsh shell
@popolon Haha awesome! 😀
@lupyuen Thanks :). It looks like lot of RISC-V based SoCs are supported, but the information in documentation strangely changes depending on version. I give here the links in different releases documentation.
Bouffalo Lab BL602, BL604, in stable
Esspressif ESP32-C3, current GIT
GreenWaves GAP8 since v7.27, based on RI5CY core (from PULP Platform)
LiteX on ARTY A7 (FPGA)
Microchip PolarFire
Sipeed Maix bit, since v9.0 (Kendryte K210 SoC)
@lupyuen
Yes, looks like nobody worked on it for now.
10.2.0 is jut out today with the ESP32C3 in documentation, but some other are no more in the docs ???
https://nuttx.apache.org/docs/10.2.0/platforms/risc-v/index.html
in the git version recipes, there is : rv32m1-vega that is a board with PULP-Platform SoC RI5CY (4 stages RV32IMC) + Zero-Riscy (RV32IEMC) cores, and, an NXP SoC with ARM Cortex M0 and M4)
The link to the RISC-V boards directory in the current git repository is probably more useful to know which one have at least minimal support
c906/smartl-c906 is based on T-Head XuanTie OpenC906 core, maintained by some people from Xiaomi and it can be emulated using (at least T-Head branch of) qemu
fe310/hifive1-revb is a discontinued HiFive1 board
mpfs is the PolarFire (was not clear for me)
