Good afternoon
Received my first own PCB back with a STM32F070CB chip...
When I pull the Boot0 pin high, I see that the host PC sees it as a DFU device...
But under normal condition when using the CDC class I see following message on the host:
[17770.689967] usb 7-2.4.4: new full-speed USB device number 31 using xhci_hcd
[17770.690061] usb 7-2.4.4: Device not responding to setup address.
[17770.898063] usb 7-2.4.4: Device not responding to setup address.
[17771.105939] usb 7-2.4.4: device not accepting address 31, error -71
I assume this has something to do with HSE as DFU mode always use internal oscillator?
How can I verify that the HSE is working?
When I just a LED blinking code in main() this works fine, regardless is choosing external or internal HS oscillator...
Or maybe something else broken in my hardware?
thanks in advance
