No existing Linux-based RTOS that I know of will run on a microcontroller. Not enough Flash for program memory or RAM for volatile storage. Can any useful Linux

No existing Linux-based RTOS that I know of will run on a microcontroller. Not enough Flash for program memory or RAM for volatile storage. Can any useful Linux-based RTOS kernel fit into 1MB of non-volatile storage and use less than ~512KB RAM; would love to know of one if it exists!
- SAI_Peregrinus 9y agoReplied as a sibling, and it certainly doesn't qualify as useful, but Dmitry Grinberg wrote an ARM emulator for AVR, soldered a SIMM to a board with an ATMEGA1284P and an SD card on an SPI bus connection, and got Linux to boot. The 24MHz clock rate is effectively reduced to about 6.5kHz, but it might be possible to find a use for such a device.
