Hi team,
We are experiencing some start up issues on the TM4C1231D5PM.
We have a good 3.3V rail, a good 1.2V output on the LED decoupling showing that the internal LDO is working, Reset is high (external pull up), and Wake_n is low (grounded). But the built in bootrom using the PIOSC doesn’t seem to be working.
The question is does the TM4C1231D5PM allow the main crystal to startup on power up automatically regardless if you select it as a clock source or not?
Thanks,
Jacob
