Resetting a SHARC+ Core Through Another Core issue

Hi, the engineer who developed this code is on vacation this week. We'll try and get a response to you as soon as we can.

Dave

Hi Dave,

    As soon as you have any response, please let me know! Thanks for the attention!

Best regards,

Raphael

Hi Dave,

Raphael and I are working on the same project so we are both looking forward to hearing from the engineer.

We have also tried the following: 

• Added a while(1){} right after recv_arg(&argc, &argv); so that there’s absolutely nothing configured by the Sharc processor (no DMA, hardware / memory access, etc.).
• Commented out lines #82 to #98 in app_startup().
• Left uncommented lines #85 to #89 in the previous app_startup() snippet.

Also, if we load the Sharc symbols on Sharc 1 from CCES after the first loadSharc is issued from Linux we can connect to the target without any problems. However, after the second loadSharc is issued and it gets stuck at Waiting for sharc, we can no longer connect to the Sharc 1 processor from CCES without performing a hard reset of the board: 

Hope this information helps troubleshoot the issue. 

We'll be happy to provide any further detail that you might require. 

Regards. 

Manuel

Thanks,

This is helpful.

Just to confirm which versions of CCES and the Linux add-in are you using?

And what EZ-KIT are you running the software on?

Dave

Hi Dave,

thanks for the prompt reply. 

We are using a custom board that we have designed where both a SC589 (where the issues occurs) and a SC573 live. 

This is the actual chip: 

It's a 500MHz part. The markings atop of it are:

• ADSP-SC589-KBCZ-5B
• 42 19500 1-1.0
• 1819 KOREA

The CCES version we are using is 2.8.3. 

Let me know if you need further information. 

Manuel

Hi Dave, 

I was wondering if you may have any news on this issue.

Thanks! 

Manuel

Hi Manuel,

Do you see your SHARC+ code looping in your while loop or in the recv_arg() function?  Do you actually pass args into your application? 

Try moving your while loop before the recv_arg() function and see if you're able to load multiple times.

Also, maybe something in the runtime start up code is causing an issue.  You can put a loop in <sharc core 1 project> -> system -> startup_ldf -> app_startup.s file somewhere after start: label. A simple loop would be

nop;

jump(pc, -1);

You can start moving this loop further down the code if multiple re-loads are successful.

Also, is MCAPI being compiled into your sharc application?  If it is, try removing it.

Regards,

Gabby

Hi Gabby,

thanks a lot for the quick reply.

Unfortunately no luck with the suggested tests.

McAPI is part of the project but it was removed without success.

In all cases loadSharc hangs at the Waiting for sharc statement. This is the full Linux output:

You will see that the first load is successful (even though it keeps Waiting application to start up because the Sharc code never reaches the recv_arg() function). Then, the second attempt to loadSharc hangs at Waiting for sharc.

When loading the version without McAPI, the PC was stuck at location 0x43 which seems to correspond to the reserved region of the L1 memory (Boot ROM maybe?):

By the way, we are not passing any args to the Sharc application.

Overall, what I'd like to stress out is that on the SC589 EZ-KIT, loadSharc seems to work just fine and in a repeatedly manner.

Please let me know if you need more info from our end and I'll be more than happy to provide it.

Thanks for your assistance so far.

Hi Gabby, 

I was wondering if you might have any news about this issue. 

Thanks.

Manuel

Hi Manuel,

In the debug statements, does it show "Arguments to be passed: Unused" on the Ezkit? 

Can you try again with MCAPI  installed?  The argument receive interface uses the memory space that MCAPI would use. 

Can you see if that debug statement also shows up on your board when MCAPI is installed?

Have you tried to port the simple GPIO/LED toggle program that comes with the EE-Note over to your board?  Does this load and run correctly?  Can this program be loaded multiple times?

Regards,

Gabby
