Do you know some opensource OSAL about freeRTOS ?

@Roger : can you clarify what you are referring to by OSAL?

If you are referring to the lwip\_osal, you might look at the implementation in the [STM32U5 IoT Reference Integration](https://github.com/FreeRTOS/iot-reference-stm32u5/tree/main/Common/net/lwip_port), which is based on the [implementation in the amazon-freertos repository](https://github.com/aws/amazon-freertos/tree/747f07402a744ec839ed9950e841142408abd6b0/libraries/3rdparty/lwip_osal).

Can provide information on the use case for the OSAL (assuming operating system abstraction layer). Why do you need it?

- Our company writes a OSAL(uCos) by itself, It’s light and easy to use.
- So, I want to find the OSAL of freeRTOS.

Could you provide additional information on what functionality you expect from the FreeRTOS OSAL?
