TDA4VE-Q1: UART issue on TDA4VE EVM

Django Wang

Part Number: TDA4VE-Q1

I couldn't find the root code of "UART_printf" at the "ipc_trace.c" in PDK of "ti-processor-sdk-rtos-j721s2-evm-09_01_00_06":

So where is it so that I could figure out the details of uart pins on EVM?

If I want to look up the print log of bootup on MCU2_0 or MCU2_1 core instead of IPC method, what should I do?

Hi,

You can find the implementation at <PDK>/package/ti/drv/uart/src/UART_stdio.c

I am not really sure if I am getting the question here correctly, can you please elaborate?

I've completed the work about making the whole install package of SD card as the TI instruction. Thanks a lot!

However, I couldn't find any printed info. related bootup or ipc on the uart serial port of MCU sides after I reboot the EVM.

Now,it seems to execute the cmd below to look up the log printed by MCU side:

How should I do if to print log on MCU2_0 or MCU2_1 core could be done when EVM bootup?

Hello,

You can see the print on main domain UART where the A72 is booting up the cores.Are you running IPC echo test or vision apps on MCU2_0 or MCU2_1 ?
