Part Number: TMDXEVM3358
Hi Experts,
According to the user guide, if UART1 is used, it is connected to J10 on the daughter board.
However, the resisters R232 and R236 on the base board are DNI, so it seems it requires the modification for J10 on the daughter board.
Are UART2, 3, 4, and 5 usable without any modification for the daughter board?

The baseboard has one RS-232 connector (DB9 male) for one of the UART's. The general purpose daughterboard has 3 more DB9 RS-232 connectors (male). The muxes on this daughterboard (implemented in the CPLD) allow the UART's on the AM335x processor to be connected to these 3 connectors. UART0 is always connected to the DB9 connector on the base board. See the pin use document later in this user guide for the profiles which support connection of the UART's 1 through 5 to these connectors on the daughterboard. When a profile is selected that enables a UART for use, the UART's are assigned to the DB9 connectors from UART1 to UART5 starting at J10, then to J12, to J14, and then back around to J10. Therefore, when enabled by the profile selection:
AM335x UART1 => J10
AM335x UART2 => J12
AM335x UART3 => J14
AM335x UART4 => J10
AM335x UART5 => J12
Thank you very much for your check.
Best regards,
Hitoshi
