I am having problems getting the external crystal oscillator to run correctly.
It has a dc offset of approx. 1.5V but a peak to peak of only 380mV.
The circuit is based on the STM32F429 Discovery board which produces a
very healthy clock.
Can anybody suggest what may be the cause of this issue.
The clock config code is
//Configure HSE clock for main system clock
OscillatorType = RCC_OSCILLATORTYPE_HSE;
HSEState = RCC_HSE_ON;
PLL.PLLState = RCC_PLL_ON;
PLL.PLLSource = RCC_PLLSOURCE_HSE;
PLL.PLLM = 8;
PLL.PLLN = 336;
PLL.PLLP = RCC_PLLP_DIV2;
PLL.PLLQ = 7;
