osMutexWait() function before the RTX osKernelInitialize()

zunda over 5 years ago

Hi.

If I call the osMutexWait() function before the RTX osKernelInitialize() function is executed, an error is returned naturally.
After that, I call the osKernelInitialize() function. Is there any adverse effect of reading the osMutexWait() function?
What kind of scene is, the two devices (EEPROM and ADC) accessed by SPI I/F are exclusively controlled by MUTEX,
but it is necessary to read the EEPROM before starting the thread when the power is turned on.
Thank you.
