In my code , I implement the communication between the PC to the bf548 through uart1 .
after adding initialization of USB driver in my code , I'm loosing the communication through uart1.
does someone has a clue why ?
UART is not functioning or USB?
By default USB interrupts are at IVG11 priority and UART uses IVG10 for rx/tx DMA and IVG7 for status. You may have to adjust the UART interrupts if USB interrupt is being preempted by the high priority UART interrupt. Check shell browser example that uses both UART and USB together. InitServices.c has the interrupt configuration.
