Part Number: 66AK2E05

Tool/software: TI-RTOS

I'm developing SMP based application on TI-RTOS.

I wrote code and that works well in CCS environment.

But when i flashed into nor spi. It does not boot.

I set "true" Core.useKernelCmd in RTSC cfg.

Core.useKernelCmd=true;

And I build it to make .out

Then I made rprc image & multicore image as follows..

out2rprc xxx.out rprc

MulticoreImageGen LE 55 app 4 rprc

copy the output into Processor SDK's prebuiltImage folder and flashed using script.

%DSS_SCRIPT_DIR%\dss.bat program_evm.js tmdsevmk2e-le

After resetting the terminal always shows the SBL log message and stops.

**** PDK SBL ****

Boot succesful!

Begin parsing user application

When I flash single core Non-smp Image, It always boots well and works.

Would you please tell me the correct method for flashing SMP based app in TI RTOS.

Can you please provide your out files and boot images here so that we can reproduce this issue on the K2E EVM. My understanding is that the SBL is tested with processor_sdk_rtos_k2e_4_00_00_04\demos\posix-smp.

Does the same issue occur with that demo as well ?

Rahul

The posix-smp demo works in CCS debug mode.

But when I flashed into 66AK2E evm, it does not works.

the log shows pending in secondary bootloader.

The boot image is made using

>out2rprc dhry.out rprc

>MulticoreImageGen LE 55 app 4 rprc

======================================================================
And here is one of my works to test SMP mode application. It works well in CCS debug mode.

And in flashing test it fails in bootlaoder.

Boot image is made also using above scripts.

JungKeun,

I dropped the ball on this topic as I was side tracked on a different issue. I am picking this up from where we left and will try to reproduce this and get back to you soon.
