In iMX6 SoloX development board design(SPF-27962), UART1 and UART2 are dedicated for A9 and M4 respectively. Does these pins have to be maintained for custom boards design or debug UART can be changed to any of the other UARTs available?
Hi,
Debug UARTs could be changed, but it is required to consider all the proper settings. Please refer to the following Community threads for details:
imx6 debug uart change
Change debug UART
imx6q change uboot debug uart 1 to uart 2
The main issue of not having externally available the UART1 could be in case of requiring the Serial Downloader Mode by UART instead of by USB, because the serial downloader UART cannot be changed on the ROM code.
Hope this will be useful for you.
Best regards!
