AM62P: DDR Margin Firmware does not have any output on terminal.

Edgar Reyes
Prodigy 30 points
Part Number: AM62P

Tool/software:

Hello, I´m trying to run the DDR Margin Firmware on a AM62P device using UART boot mode, but after download the binaries I get output from both R5F cores (WKUP and MCU) but not from A53 core.

I´m using the <mcu_plus_sdk_am62px_11_01_00_16> following files:

--cfg = default_sbl_uart_linux_hs_fs.cfg

--bootloader = sbl_uart_linux.release.hs_fs.tiimage
On the MCU and WKUP R5F cores I´m downloading Hello world examples.
On the A53 core I´m downloading the DDR Margin firmware converting from .out -> .rprc -> unsigned.appimage. 
All binaries are successfully loaded as show in the following image:
 
So my question is do I need to make and additional configuration to get  the output from the DDR Margin Firmware?
On the readme file said all UART configuration is made by the firmware itself. 
-----------------------------------------------------------------------------------
When I flash the program instead booting it from UART, the follow information pop up at start:


Thanks in advance.

    Greetings Edgar,

    I do not have an AM62P board on hand to verify this, but I will let you know when I obtain one. My initial observation would be that based on the boot log, it strangely doesn't appear to be powering on an A53 core (cores present is just the wakeup R5).

    Instead of the Linux UART boot, can you try the standard SBL UART boot? It's also a prebuilt image and should be something like default_sbl_uart_hs_fs.cfg.

    Sincerely,

    Lucas
