Hi
I've finally reached to generate code for ESP32 using pysimCoder. My
board is a OLIMEX ESP32-POE board,
Starting from the esp32-devkitc:wifinsh configuration we set
CONFIG_ARCH_CHIP_ESP32WROOM32=y
and the generation of the nuttx code is ok.
The problems start when I do a "make export":

I agree with Greg!
If we can have stable operation of priority inheritance with semaphores
then we can build mutex as a macro based wrapper (mostly as it is now).
One thing that I can think of is adding a "mutex" attribute to a semaphore
and creating a separate task list for faster scheduling, bu

is irrelevant.

Hi, All:
The main purpose of this PR is to separate mutex and semaphore and to improve
the performance of mutex.
Regarding the issues mentioned in the email , here is a summary:
1. The number of system calls will increase.
After separating mutex and semaphore, futex support will be added in th
