Tool/software:
we want to use the boot from UART option for the first bring up of our custon board, since the eMMC flash will be blank. the TRM says use port 0 UART. but there are three different "port 0" on the tda4. there's the MCU-UART, the WAKEUP_UART, and the A53 UART. which one am i to use? thanks!
Hi,
Take a look at the 'Flashing SoC Initialization Binary' section from the MCU+ SDK docs. Specifically, looking for the string printed on the UART console as shown below.
Additionally, in the EVM user guide, you can see the COM port mapping to UART instance shown below. Here you can see which port should be WKUP_UART, MCU_UART, etc.
Thanks,

Hi,
Based on the image below in the TRM, it says ROM code booting from UART uses UART0.
Based on the image from the EVM user guide that I am reattaching below, UART0 maps to COM port 3. This will be the A53 UART.
Thanks,
Neehar
