LPI2C DRV + FreeRTOS OSIF error

Hello,

 

I currently try to implement my eeporm interface in a project using the FreeRTOS V10.0.1 port in PE. Therefore, I added the LPI2C Peripheral Driver in PE. With this configuration, I can see communication on the I2C lines but the application never ends the blocking LPI2C functions.

 

I tried to reproduce the issue in a smaller project. Using only the LPI2C driver, communication is working. This configuration is using the osif_baremetal.c.

As soon as I add FreeRTOS to the configuration, osif_baremetal.h references to osif_freertos.c. From this moment on, I2C communication fails. Anyway, if I set breakpoints inside the OSIF_SemaWait(...) function to get some delay, the interface is working.

My conclusion: The issue is caused by the freertos osif.

 

I attached the small project that reproduces the issue.

 

Can anyone please give me a hint how to fix this problem?

 

Thanks and best regards,

Markus
