Hello!

is it is the same case for the FreeRTOS i2c driver?

I'm trying to use two i2c buses as master (i2c0 and i2c1) but if I initialize the I2C1 with MCUxpresso IDE config tool the I2C0 don't work anymore.

The hang happen in I2C_RTOS_Transfer on file fsl_i2c_freertos.c, the line

(void)xSemaphoreTake(handle->semaphore, portMAX_DELAY); never returns.

It's because he interruption was never catch on callback: I2C_RTOS_Callback

If I disable the I2C1 driver, then I2C0 works normaly.
