Feature Request: RISC-V (riscv64) support for M5Stack Arduino Libraries
Summary
Request to add RISC-V (linux/riscv64) support for M5Stack Arduino Libraries and associated builtin tools, to enable compiling and uploading M5Stack firmware from RISC-V based host machines.
Hardware
- Host machine: Orange Pi RV2 (CPU: Ky X1 RISC-V, 8 cores)
- OS: Ubuntu 24.04 Noble (linux/riscv64)
- Target device: M5Stack Tab5 (ESP32-P4)
What works
- ✅ Arduino CLI compiles successfully from source on RISC-V (Go 1.22.2)
- ✅ M5Stack and Arduino package indexes download correctly (
arduino-cli core update-index)
- ✅ arduino-cli configuration works as expected
- ✅ M5Stack Tab5 programs and runs correctly when compiled from a Windows/x64 host
What fails
When running arduino-cli core install m5stack:esp32@3.2.5 on a RISC-V host, the following errors occur:
Error: downloading builtin:ctags@5.8-arduino11 - no versions available for the current OS
Error: downloading builtin:dfu-discovery@0.1.2 - no versions available for the current OS
Error: downloading builtin:mdns-discovery@1.0.12 - no versions available for the current OS
Error: downloading builtin:serial-discovery@1.4.3 - no versions available for the current OS
Error: downloading builtin:serial-monitor@0.15.0 - no versions available for the current OS
Error: downloading m5stack:esp32-arduino-libs@idf-release_v5.4-858a988d-v1 - no versions available for the current OS
The last error message explicitly suggested contacting M5Stack support, which led to this issue.
Context and motivation
RISC-V is a rapidly growing architecture in the maker and IoT community. Single-board computers like the Orange Pi RV2 are increasingly being used as IoT hubs and development platforms. Being able to compile and upload M5Stack firmware directly from a RISC-V host would be extremely valuable for projects where the RISC-V board acts as the central hub managing M5Stack devices.
Request
Could you please consider adding RISC-V (linux/riscv64) binaries for:
m5stack:esp32-arduino-libs- The associated builtin tools (
ctags, dfu-discovery, mdns-discovery, serial-discovery, serial-monitor)
Additional notes
- I am happy to test beta builds or provide additional information if needed.
- Note that the builtin tools are an Arduino project dependency - it may also be worth raising this with the Arduino team at https://github.com/arduino/arduino-cli/issues
