Do you define both HAL_UART_DMA & HAL_UART_ISR to the same value?

i just only define HAL_UART。

and i saw zstack was define HAL_UART_DMA as default，

but i don't know how to change the UART mode

although i just add HAL_UART_ISR define in option item， it can not be rebuiled

You can try to change the define value of HAL_UART_ISR and HAL_UART_DMA in hal_board.cfg.h. Don't define it directly.
