CCS/66AK2H14: how to flash the application into multiple cores.

Hi Rahul,

Thank you for your quick reply.

Another common error that we have observed is the app should not be loading sections into location from where SBL runs. make sure that you don`t have code section in app at the following location:

SBL_MEM (RWX) : o = 0x0C0B0000, l = 0x3FC00 /* MSMC Shared Memeory */

------------------------------------------>>>>>>>>>

I checked in memory map of my application , It is not using that region of MSMC .

Can you please also indicate what is the PC when you connect to the the DSP(without GEL) is this in region indicated in your application map file ?

PC is at 0x20B11720 , this region is not indicated in map file of my application.

What is expected on the UART after the application starts?

application output prints.

do you have UART prints that should show when the application is executing ?

yes.

If  I flash the application into core 0 ,  application runs and gives all the prints on the terminal  when I change the boot mode.

problem is only with other cores. when I flash the application to other DSP cores it will get stuck at

Jumping to user application....

What may be the problem with other cores?Please help me to solve this.

Hi Rahul,

Thank you for your support.

1. I debug SBL.out for core 1 , it was failing at

if (entry.entryPoint_DSP1 != 0)

   {

       SBL_DSPBringUp(1, entry.entryPoint_DSP1);

   }

this point. Entry.entryPoint_DSP1 = 0x81FAE0. When it reaches this point it gives some error. I have attached the screen shot for your reference.

but this problem was not there when I flash the code to DSP core 2. In DSP core 2 it will bring up DSP core 2 as per

   SBL_DSPBringUp(2, entry.entryPoint_DSP2);

I didnt get any error here , but still when I change the boot mode to SPI it will get stuck at

Jumping to user application....

2. There is no overlap of address between DSP core0 app and DSP core1 app

3. When I flash two application on core 0 and core 1, entry point will be

entry.entryPoint_DSP0 = 0x81FAE0

entry.entryPoint_DSP1 = 0x840420

I didn't find any error accept for core 1 when I debug SBL.out . I am not able to track down the issue.

Please help me with this.

Thanks and Regards,

Hi Rahul,

I mapped the application  to MSMC and tried but still it is getting stuck at same point.

I debug the sbl .out ,

entry.entryPoint_DSP2 = 0xC00EAC0.

I attached my .map file for your reference.

Hi Rahul,

one more thing that I observed is , When I connect to core 2 through JTAG in spi boot mode it is giving some error.

I have attached the screen shot of the error for your reference.

and PC was at 0xAC9A5EF4.

This error was not there when I tried to connect to core 0.

Hi Rahul,

When I try to debug the application flashed to core 2 by loading the symbols , it is giving error.

I have attached the screen shot for your reference.

Hi Mahima,

Just to confirm the settings,

Are you able to run post example provided by TI on your setup?

I hope you are following below link, Please confirm.

Thank you.

I tested the same on EVM by flashing the post application on DSP core 1 using flash_writer application.
To create the app for core 1:
out2rprc\bin\out2rprc.exe C:\ti\pdk_k2hk_4_0_9\packages\ti\boot\post\evmk2h\bin\post_evmk2h.out C:\images\app_rprc

multicoreImageGen\bin\MulticoreImageGen.exe LE 55 C:\images\app 6 C:\images\app_rprc

When I changed the boot mode to SPI , It got stuck in
jumping to user application......
