Cyclone V: Core 0: Bare-Metal, Core 1: Linux OS

Hello,

I have tried the examples and it works. The functions such as TSKsetCore and TSKcreate, which are used to set the core and assign the program snippet to run on the desired core, has its source code hidden, as obvioulsy, it is not open source I guess. These functions are the ones most interesting for me. As I can roughly guess, that here, the core 1 is assigned to run a specific block of code. Now, I have a simple question---As I dont want to use the SMP RTOS version just to assign the core 1 to do a specific task;--- I need to just know the following;

"How can I write a short sequence of instructions for Core#0 in bare-metal to inform core#1 of where to start executing the program?? "

If I know this answer, then I am through hopefully.

P.S: I have run two different bare-metal programs on two corresponding ARM cores in Cyclone V (Cortex-A9) in DS5 using JTAG line. The SDRAM is shared between the two cores as is evident from the cache settings which is set to "shared" by default. Core 1 is held in reset after a system reset is issued (Cold or warm). After reset, Core 0 is allowed to execute instructions. I know how to release the core 1 from reset and it works perfectly. In DS5 using JTAG chain I could easily run two different programs on Core#0 & Core#1, but my question pertains to the bare-metal program running from SD card.

Hi,

Based on my understanding, you would probably need a start up sequence for the Core#1 before releasing reset.

Hi,

Obviously, but what should I do in the start-up sequence to inform Core#1 of where to start the program? Could you please give me hint, probably a short textual instruction of what should be done sequentially. There is no help available in the TR manual about this topic specifically nor in the forum.

Hi,

I apologize we do not have the documentation regarding the examples on this.

As mention previously, for examples I suggest that you refer to https://code-time.com/baremetal.html.

Regards.

I guess this forum was also meant to address issues that are not being addressed well in the documentation. This is no excuse as I have bought your Product and the functionality exists so I should be informed of how it works at least some hint of what should I do if it isn't in the documentation. I have spent almost two months figuring it out myself and now you are just indirectly saying that I could not take help from anywhere so my efforts were futile. You are again directing me to this site as if I haven't gone through it. My long previous reply was meant to explain to you why it isn't relevant in my case. I am really disappointed by Intel's customer service. It's a pity that such important questions could not be answered in the forum.

Hi,

I sincerely apologize that we do not have the design examples from our design stores that could help with your request.
