Issue deploying a DDR application to eMMC

[mcergun]

I've been playing with the hss and hss payload generator but I can't seem to figure out how to create and deploy an SMP application onto the eMMC.

mss_entry.S seems to route any IMAGE_LOADED_BY_BOOTLOADER == 1 applications to u54_single_hart function, which just updates their hartid with MPFS_HAL_FIRST_HART

Is this the intended method?

When I compile an application with multiple hart methods (u54_1, u54_2, etc.) and create a payload accordingly, the application only works on a single core, or it doesn't work at all.

How would I compile an application and create the payload if there are multiple harts involved?

Hey @mcergun 😄

This feature was initially planned for single hart applications, we're having a look into it and we'll get back and let you know what the easiest way to get it working with multiple harts would be. I have a suspicion that updating line 224 of system_startup.c to:

hls->my_hart_id = read_csr(mhartid);

would work but we need to test it out to be sure

No problem, I mean do you have a local support engineer? I don't really want to post anything pre-release here but I could share it with you directly through email.

We have an update for this completed internally and it should be released soon anyway :)

Any unofficial ETA on the release? If that's soon enough I may wait for the release as well.

Hopefully next week is the best I can give you?

Hi @mcergun a bit late but support is out now in the latest version of the platform

How does this support solve the problem? If a bare metal application does not use the platform, what needs to be done to execute an application on all cores using the hss payload?
