TMDSSK3358: TMDSSK3358 use 3x UART

Part Number: TMDSSK3358

customer want to test 3x UART, 1x USB, 1x Ethernet on the TMDSSK3358 EVM. Is this possible?

UART0: used by USB to UART chip (FT2232HL)

UART1: pins used Wifi module

UART2: pins for Zigbee header

Are these signals available for UART access? Or is HW modification needed? Are other UARTs better to use?

Regards, Holger

  • The SK boards typically utilize most, if not all of the processor pins.  This means that there are limited opportunities for flexibility of testing interfaces not already configured or changing the connected components with some extensive modifications. 

    A better board for this purpose may be a BeagleBone Black. It already has Ethernet and USB interfaces available, plus it has access to all 4 UARTs via headers
