Uart3 in stm32f103c8 not working

[ABhat.7]

hi,i am trying uart with dma in stm32f103c8 with uart3 after n try i found that uart3 in stm32f103c8 is not working then in polling I observed that the TX pin is not getting high and low so I toggle that pin it toggles as a digital pin so I think there is some problem in uart3 can someone provide solutions that how can i use it

Should i enable nvic irq for that uart as i have already done configuration for dma nvic​

Sorry have you found any solution>? I`m experiencing the same issue, when sending UART in polling mode, it`s fine. As soon as I enable timer, it starts sending random data. F103chip. Thanks!
