Hello. Are there known FreeRtos ports for EM3588 or similar chips? Thanks.

If I recall correctly these devices have a Cortex-M core, so no porting should be needed as such for FreeRTOS, just the creation of a project that builds the code. The following links may help: http://www.freertos.org/Creating-a-new-FreeRTOS-project.html http://www.freertos.org/porting-a-freertos-demo-to-different-hardware.html
