Hi, I'm using QNX on A72. How do I run another firmware on R5? Where can I find remoteprocX or rpmsgX on QNX running on A72?

Thanks in advance

Hello Artur,

When QNX is used to run on A72, the bootloader being used, whether SBL or SPL+UBOOT, needs to take care of the standard support for loading the firmware to other cores (including R5Fs). Please refer to this developer note in the RTOS SDK for your understanding --> https://software-dl.ti.com/jacinto7/esd/processor-sdk-rtos-jacinto7/10_00_00_05/exports/docs/psdk_rtos/docs/user_guide/developer_notes_bootloaders.html

Once the firmware is loaded and running from QNX A72, we can use the IPC resource manager to communicate with these remote cores (including R5F). Please refer to the QNX SDK documentation. https://software-dl.ti.com/jacinto7/esd/processor-sdk-qnx-jacinto7/10_00_00_04/exports/docs/qnx_sdk_components_j721e.html#ipc-resource-manager

We hope this helps clarify your query.

Thanks,
