Other Parts Discussed in Thread: SEGGER,
Hi,
I have an issue where the target does not come up after power up. The TRST line on controller is pulled low with 10K ohms (as per controller datasheet). So this line is low. The target starts to work as soon as a 3.3 V is applied on TRST line. We use a Segger JLink for programming and debugging. According to JLink manual TRST line should be pulled high to 3.3 V - this contradicts with the user-manual for the controller (TMS470R1B1M). Could you verify if TRST line should be pulled high or low?
