How to create uart on my target board

[yichen]

Hi,

I already built my image and I can find uart file descriptor /dev/ttymxc0

But there is 4 uart on my target board

How can I generate it?

Thanks.

Hi

Which BSP are you using?

For Kernel 3.10 or higher kernel dts file enables the UART.

Thanks
