"placement fails for object "Cla1Prog", size 0x2da (page 0)"

Daniel,

Note that you can only run code on the CLA from L3 RAM. You will need to copy this code over to L3 and then configure L3 to be a CLA RAM to run it.

Hi Andreas, hi David,

thanks for the fast response.

I have no idea how to that.  I tyed to somethink like this:

MEMORY
{
PAGE 0 :
   /* BEGIN is used for the "boot to SARAM" bootloader mode   */

   BEGIN      : origin = 0x000000, length = 0x000002
   RAMM0      : origin = 0x000050, length = 0x0003B0
 /*  RAML0L1    : origin = 0x008000, length = 0x000C00*/
   RAML0L1    : origin = 0x008000, length = 0x001000
   RESET      : origin = 0x3FFFC0, length = 0x000002
   IQTABLES   : origin = 0x3FE000, length = 0x000B50     /* IQ Math Tables in Boot ROM */
   IQTABLES2  : origin = 0x3FEB50, length = 0x00008C     /* IQ Math Tables in Boot ROM */
   IQTABLES3  : origin = 0x3FEBDC, length = 0x0000AA     /* IQ Math Tables in Boot ROM */

   BOOTROM    : origin = 0x3FF27C, length = 0x000D44


PAGE 1 :

   BOOT_RSVD   : origin = 0x000002, length = 0x00004E     /* Part of M0, BOOT rom will use this for stack */
   RAMM1       : origin = 0x000480, length = 0x000380     /* on-chip RAM block M1 */
   RAML2       : origin = 0x009000, length = 0x000C00
 /*  RAML2       : origin = 0x008C00, length = 0x000400*/
 /*  RAML3       : origin = 0x009000, length = 0x001000*/
}


SECTIONS
{
   /* Setup for "boot to SARAM" mode:

      re-directs execution to the start of user code.  */
   codestart        : > BEGIN,     PAGE = 0
   ramfuncs         : > RAMM0      PAGE = 0

   IQmath           : > RAML0L1,   PAGE = 0
   IQmathTables     : > IQTABLES,  PAGE = 0, TYPE = NOLOAD

But I always got  new error messages:

warning: creating output section "Cla1Prog" without a SECTIONS specification
   library "libc.a"

"../28035_RAM_lnk.cmd", line 120: error: run placement fails for object

   ".stack", size 0x300 (page 0)

error: unresolved symbols remain

if I do it in normal configuration (change the uncomment code) the I'll get these error messages:

Can someone help me again?

Tank you

I got the fail.

But now there's a problem I can't understand.

I'm using the body of the "cla_adc_fir" example. Just the main, shared and cla sections will be changed by myself. If I'll run my programm, everytime I'll  jump into the "DSP2803x_DefaultIsr.c" into the Illegal operation TRAP (interrupt void ILLEGAL_ISR(void)  ).

Can someone tell me what why the program could be jump into this interrupt (just in general)

Thank you

Greets

Daniel,

The ILLEGAL_ISR is executed if an instruction fetch retreives a value from memory that does not correspond to a proper opcode. It is likely you are making a call to a RAM location that has not been initialized. I think if you return from the ISR it should bring you back to the offending address. Or, it might be stored in the RPC register, I can't remember.

Dave Foley

hi David

when I run code on the CLA from L3 RAM,but I only use 2K,can I use the other 2k for CUP?if you can ,how to do that?

Can you help me ?

Thank you
