I am new to KSDK and Kinetis processors, but I have I2C working except that the Processor Expert code is not properly setting the Open Drain Enable bit for the SDA and SCL pins. When I try to set the bit in my code, an interrupt occurs. This is in a "bare metal" system. I'm trying to set the bit like this:
volatile uint32_t *portc10 = (void *)0x4004b028;
*portc10 |= (1 << 5);
The interrupt occurs when portc10 is dereferenced.
I have no idea why this is happening unless there is memory protection being turned on by something, but that should be the case in a bare metal (standalone) platform. If so, how do I turn it off so I can set this bit?
