I started with the TWRK70F120M BSP, cloned the BSP and PSP, and made clock modifications for my platform specific requirements. Then I created a new MQX 4.1 project, used the USBD-CDC example project based on my new BSP. I get everything compiled and deployed, however, when I attempt to pause when debugging I get a GDI Protocol error, Stop Failed. Any ideas?
I noticed that in PEx, I cannot select System Oscillator 1 for MCG external ref. clock source in my Clock Source Setting 0. So my question next is: Does PEx with MQX, USBD, on the BSP I chose require OSC0 as the MCG external ref. clock source? I cannot seem to select OSC1 even though it's enabled and OSC0 is disabled.
The TWRK70F120M Tower platform uses a 50MHz oscillator for the clock on Oscillator 0 input. Our platform uses only the 12MHz clock input to Oscillator 1, and no input to Oscillator 0.
