I am enabling UART3 Driver on Nucleo 070RB.
When calling uartStart witch UARTD3 system crashes here.
I am usinbg mcuconf.h from demos and here DMA stream id is set to 6 and 7. I didn't go deeply into implementation, but guess that it referes to number of DMA channels supported by µC and this one has only 5 channels (referente manual page 152) (and hal accepts those channels. (If I understand well this implemenation))

Hi,

Fixed in 16.1.x and 17.6.x, there were similar problems also for SPI and I2C DMA channels.
