Hi
TI support teams.
J721EXSOMXEVM: I'd like to know whether there is any chip(s) being controlled via UARTx(send cmd or data) or not in this EVM .
Here's my question：
1、If existed, which .dts file should i take a look for pin-mux ?
2、Where is the corresponding drivers located ?
Best Regards,
Murphy.
Hi,
The ones that are brought out are all used for console UART & do not control other chips.
They are brought through a QUAD PORT FTDI(MAIN_UART0/1/2/4) & a DUAL PORT FTDI(for WKUP_UART & MCU_UART).
MAIN_UART0, MCU_UART, WKUP_UART are all used for console.
What specific controlling chip are you looking for? What external chips do you want to control?
