RTOS/66AK2G02: Booting without help of CCS(standalone boot) or SD card boot.

Megharaj,

You are referring to correct documentation to convert your images to bootable images.  Here is a quick summary from my notes of creating bootable audio application binary:

Since you are using Processor SDK Audio, let me share some insight into other things that may be required to get your system boot working efficiently:

• Ensure that the DSP and ARM binaries are not using MSMC region used by K2G SBL. For SBL memory usage refer to  pdk_k2g_x_x_x\packages\ti\boot\sbl\soc\k2g

• Performance audio application uses IPC start to synchonize application start between ARM And DSP. You may be required to add a delay prior to IPC attach on the ARM to allow DSP to complete initialization and get ot IPC attach by the time ARM calls this API.
• We had noticed that ARM and DSP application from performance audio has large heap buffers that add large segments of zeros to the boot image. You can change the BIOS configuration to remove these segments to speed up the boot. (Optional)

Hope this helps.

Regards,

Rahul 

Hi Rahul,

Thank you for the replay. But this dint help. I am not able to boot from sd-card, also from CCS after adding the delay in arm before IPC attach.

After folowing this link I followed the below procedure.
./out2rprc.exe test_arm.out test_arm.rprc
./out2rprc.exe test_dsp.out test_dsp.rprc
./MulticoreImageGen.exe LE 55 app 0 test_arm.rprc 5 test_dsp.rprc

I have added delay in test_arm before ipc_attach in systeminit.c as shown below. But it dont help.
#if 1 // debug: dummy load
for (k = 0; k < 10000; k++) // Even tried 1 , arm suspends
{
tsStart=readTime32();
pfpBegin(PFP_ID_MAIN,0);
clkWorkDelay(CLK_WORKCNT_PER_MS); /* This should take about 750,000 cycles to execute, or 750e3/600e6=1.25 msec. */
pfpEnd(PFP_ID_MAIN,0);
tsEnd=readTime32();
}
delta = tsEnd-tsStart;
#endif

This is not working. Console message is showing,

**** PDK SBL ****
boot succesfil!

SD Boot - file open completed successfully.

If I enable the delay in arm main.c IPC_start(), it will work in CCS, but still does not work in sd card.

This is my memory configuration

Hi Rahul,

Thank you for the response. 

SBL and app memory was overlapping on on-chip memory.  Moved some app memory contents to DDR3. Everything started working fine.

Thank you very much for the support.
