TMDSCNCD28P65X: C28p65 Dedicated RAM Assignment Issue

Hi Jwalant,

Thanks for your question. I will try to reproduce the issue on my end and get back to you.

Thanks,

Ira

Hi Jwalant,

I tried your cpu1 and cpu2 linker cmd files with the empty project from "C2000Ware_6_00_01_00\driverlib\f28p65x\examples\c28x_dual\empty_projects\empty_c28x_dual_sysconfig_cpu2.c", however I did not get the data verifcation error and was able to build the project. I just edited the linker cmd file from the SDK example according to your linker. 

I tried with CCS 20.4.1 and CCS 20.5

Can you try to import my project and see if you are able to build it?

If yes, then maybe the issue is not in the linker but rather some other project config.

Let me know what results you get.

Thanks,

Ira

When I imported the project I you listed here, I get the following import error. It looks like that you might have tried it with newer compiler

Hi Jwalant,

Can you help me with the exact compiler version you are using?

Thanks,

Ira

C2000 - v22.6.3.LTS, and Clang v2.0.0.STS

I noticed something strange as I follow the instructions to create a dual core project from the example of empty project. Then I added the same example code from LED dual core example. Also, updated the syscfg files on each core to match. First it gave me error about redefining CPU_LED1 and 2 on either side as the other side had defined. But removing it from CPU2 fixed the error, code builds and executes. However, LEDs do not blink. So, I looked compared the Syscfg of LED examples vs. mine. To my surprise, CPU1 syscfg from my code looks like LED example CPU2 file and vice versa! 

I noticed that the syscfg tools I have are newer than the example had. Is there a bug?

Hi Jwalant,

Let me check with the team and get back to you.

Thanks,

Ira

Hi Jwalant,

Sorry for the late reply. Can you please elaborate more on what you think is the bug? Are you trying to build C2000Ware_x_x_00\driverlib\f28p65x\examples\c28x_dual\led? And you are observing that the led is not blinking?

Meanwhile can you try to import and build this project? 

This has the same RAM linker as your project and I have built it using your compiler version. Are you able to import this and build it?

I have tested it on CCS 20.5.

Ira, 

I will be testing the code pretty soon. The aforementioned bug is that if you look at Syscfg xml file CPU1 file lists GPIO that is assigned within CPU2 sysconfig and vice versa. It should not be that way.

I imported and built the project. That works. However, the problem was not the build part. It was when I was trying to debug, it could not verify. Recently, TI CCS got updated 20.5.0.28, now when I initiate a debug session, I get "module closed" error without any further details.
