loading program in arm via dsp in EVM k2e

Hannan Khan

Hi again !!

so i have a bare metal program for both the dsp and ARM cores which do nothing but send out a hello world print to uart

i have looked into the boot examples and seen how the cores are started and put to "standing by"

my question is that how do i run my bare metal (ARM) application from dsp and is it possible to ignore the dsp core all together and jump straight to ARM cores?

booting from nand btw

thanks !!

You can set ARM NAND boot mode and flash your binary into NAND flash device.
We have separate boot mode for ARM and DSP boot (NAND, SPI, etc.,)

Hi,

I've forwarded this to the support team. Feedback will be posted directly here.

Best Regards,

yes but how are we to define that which core would run the specific set of instructions?

#ifdef _TMS320C6X
/* DSP code */
#else
/* ARM code */
#endif

#ifdef __ARM_ARCH_7A__
/* ARMv7 code */
#endif

coreNum = CSL_chipReadReg(CSL_CHIP_DNUM);
coreNum = CSL_chipReadDNUM();
You can get the core no like this.

I hope this helps.

hello Titus !!

so basically you are saying that the same code is loaded into all cores and processor and we have to separate them ourselves 1st between dsp & arm and then between arm cores using the specific core number we obtain using CSL library.

also if possible can u send a link which contains all CSL functions for ARm k2e?

thanks !!

Hi Hannan,

can u send a link which contains all CSL functions for ARm k2e?

You can refer the CSL code from K2E PDK directory.

PATH : ~\ti\pdk_k2e_x_x_x\packages\ti\csl

You can find the ARM and DSP libraries in below directory,(armv7 has ARM library and c66 has DSP library)

PATH: ~\ti\pdk_k2e_4_0_0\packages\ti\csl\lib\k2e

Thank you.

Hi titus !!

one last thing i wanted to ask is that i have tried to use the functions and came across to issues and came across "unresolved symbol CSL_chipReadReg" when i tried to add csl_chip.h
further when i tried to add csl_chipAux.h i got an error in the declaration of AMR,ARP and other registers

can u please tell me which header file i am missing?

You need to link the csl libraries in your project.
C:\ti\pdk_k2e_4_0_2\packages\ti\csl\lib\k2e\c66\release

the libraries are already set as i am able to use CSL to run UART (by using the bootexamples' uart.c)

Are you using bare metal code or BIOS based application ?
If BIOS, you can also try to import the csl driver in .cfg file.

/* Load and use the CSL packages */
var devType = "k2e"
var Csl = xdc.useModule('ti.csl.Settings');
Csl.deviceType = devType;

bare metal i m afraid...i figured that maybe it was a pdk issue so i tried updating my PDK to 4.02 (k2E) but unfortunately now i am stuck with these errors

Gtk-Message: Failed to load module "overlay-scrollbar"
Gtk-Message: Failed to load module "unity-gtk-module"

and only get macros.ini at pdk build's "MyExampleProjects"

p.s. should i make a new post for this issue?

Yes please, create a new post for your PDK issue.
