Cloudhil puts firmware on real microcontrollers

Editorial interest 77/100 Selection signal · not a rating of the site

A hardware-in-the-loop service that accepts locally compiled ELF files, flashes supported STM32 or LPC boards, and returns serial output.

Landing page captured for the 2026-10-21 issue.

For: Embedded firmware developers and coding agents
Worth noticing: Runs last at most 20 seconds before the board is erased; the site explicitly frames this as a smoke test, not a long soak.

Field notes

Users compile with arm-none-eabi-gcc locally, then submit an ELF through POST /api/v1/jobs/flash or an MCP client; Cloudhil does not compile the firmware. The page provides sample binaries for four boards and identifies a NNOK mailbox at 0x4E4E4F4B as one success signal. Payment is described as 10 credits per flash, and the page says a well-formed voucher is not spent if the bench returns 503.
