Hi,

I ran the demo application in the link below. Then I changed UART2 and set it to UART3. But it didn't work. Does anything need to be tweaked in the kernel? Is it enough to make changes only in demo application?

For example:

uart3 ==> A53 = disable

uart3 ==> M4 = enable

Hi,

Thank you for your interest in NXP Semiconductor products,

Do UART3 have a clock feed?

Do UART3 have pins initialized?

Are you using 8M-EVKB?

Regards

Hi Josephlinares,

I adjusted what you showed but it didn't work. Do changes need to be made board_init_debug and board.h ? What should we change if necessary?

Thank for your help.

Regards
