Hi,
The KSDK 1.2 fsl_i2c_master_driver created with KDS 3.0 / Pex breaks if a task tries to send or receive while another task is sending or receiving. The check for being idle sets the master->status to kStatus_I2C_Busy if it is busy but that stops the processing of the active task that is looking for kStatus_I2C_Success and from then on every access is busy.
I have changed the checks in both send and receive as follows:
if (!master->i2cIdle)
{
// return master->status = kStatus_I2C_Busy;
return kStatus_I2C_Busy;
}
and then it all seems to work OK. Now the tasks can check for busy and retry without changing the current state and breaking the current process.
Have I missed something or does that look to be a reasonable fix?
Best regards,
Adrian.
