Hi all,

Going through the diag examples provided under sdr in pdk I am not able to understand in

1. How to build and run UART_test on A72 core.

2. How to flash it to the sd card for running it on runtime rather than on boot time.

Hi,

Which SDK version are you using ? I can check.

Please note that there is limited support for RTOS apps on A72, recommendation is to use Linux/QNX

Regards

Absolutely, we are working with the Linux distro on the A72. The Linux SDK
Version: 07.03.00.05
Release date: 13 Apr 2021

The RTOS SDK Version: 07.03.00.07
Release date: 13 Apr 2021

Hi,

I didn't get your requirement. Are you looking for a UART test example on Linux ? Have you tried the out of box Linux boot on J721E on the EVM ?

If you can mention your requirement exactly I can help.

I want to test the UART at runtime from the A72 core running Linux. This is so that I can throw an error exception to the MCU island.

For that I wanted to rebuild the pdk provided in the RTOS-SDK (i-processor-sdk-rtos-j721e-evm-07_03_00_07/pdk_jacinto_07_03_00_29/packages/ti/diag).

My question is
What are the steps to rebuild the pdk and run this application on the A72 Core at runtime?

Hi Sam,

You want to load and run the UART diag application for MCU 1_0 via remoteproc ?
