Debug Error After Assign RAM L1 and L2 to CLA.

Other Parts Discussed in Thread: CONTROLSUITE

Hi, all,

I am now using the template “C:\ti\controlSUITE\development_kits\TemplateProjects\DPLibv3_4Template-F2803x” inside the controlSUITE on my F28069 Piccolo Experimenter Kit.

I have to use Solar CLA Library on my application. As mentioned in the CLA C Solar Library Module User’s Guide V1.1, I have to assign RAM L1 and L2 for CLA data memory with the following code:

// configure RAM L1, F28035 as CLA Data memory 0

Cla1Regs.MMEMCFG.bit.RAM0E = 1;

// configure RAM L2, F28035 as CLA data memory 1

Cla1Regs.MMEMCFG.bit.RAM1E = 1;

Initially, I set the build configuration as “RMA”, the CCS Debug cannot be run and with the following error: “No source available for "0x3ff4fa"”

Then, I changed the build configuration as “FLASH”, the Debug can run susscufully.

Question: Can I assign RAM L1 and L2 for CLA while I can run and debug my program in “RAM”?

I wonder if anyone can give me a hand and thanks in advance.

BR,

Barry

Dear Gautam,

Thanks for the document. It gives me the reference to know more how to write the linker command file.

BTW, I think I can find the cause of the problem. the template inside ControlSuite :C:\ti\controlSUITE\development_kits\TemplateProjects\DPLibv3_4Template-F2803x

The linker file should be 28xxx_RAM_CLA_C_lnk.cmd.

We will come across lots of errors when using CLA if we use the linker command file F28035_FLASH_ProjectName.CMD or F28035_RAM_ProjectName.CMD.

BR,

Barry
