TMS320F280025C-Q1: DMA-Transfer Data not to GS0 Ram

Part Number: TMS320F280025C-Q1

Hello support team,

I have 2K*16 in GS0 Ram but it's not enough for our application

I tried to use RAMLS4567 instead:

28002x_launchxl_demo_flash_lnk.cmd:

SECTIONS
{
   codestart        : > BEGIN, ALIGN(8)
   .text            : >> FLASH_BANK0_SEC2 | FLASH_BANK0_SEC3 | FLASH_BANK0_SEC4 | FLASH_BANK0_SEC5,   ALIGN(8)
   .cinit           : > FLASH_BANK0_SEC1,  ALIGN(8)
   .switch          : > FLASH_BANK0_SEC1,  ALIGN(8)
   .reset           : > RESET,                  TYPE = DSECT /* not used, */

   .stack           : > RAMM1

   .init_array      : > FLASH_BANK0_SEC1,  ALIGN(8)
   .bss             : > RAMLS4567
   .bss:output      : > RAMLS4567
   .bss:cio         : > RAMGS0
   .const           : > FLASH_BANK0_SEC6_7,  ALIGN(8)
   .data            : > RAMLS4567
   .sysmem          : > RAMLS4567

    ramgs0 : > RAMGS0
    ramgs1 : > RAMLS4567
    /*  Allocate IQ math areas: */
   IQmath           : > RAMLS4567
   IQmathTables     : > RAMLS4567

  .TI.ramfunc      : LOAD = FLASH_BANK0_SEC1,
                  RUN = RAMGS0,
                  LOAD_START(RamfuncsLoadStart),
                  LOAD_SIZE(RamfuncsLoadSize),
                  LOAD_END(RamfuncsLoadEnd),
                  RUN_START(RamfuncsRunStart),
                  RUN_SIZE(RamfuncsRunSize),
                  RUN_END(RamfuncsRunEnd),
                  ALIGN(8)

}

and

#pragma DATA_SECTION(u16AdcMeasCurrentByDma, "ramgs1");                   /* map the data to memory */
static volatile u16 u16AdcMeasCurrentByDma[ADC_NO_SYNC_PER_1MS];          /* array for current measurement */

And the data in u16AdcMeasCurrentByDma after DMA interrupt is all 0

Can DMA access RAMLS4567?

Are there any way I can increase the RAM area for DMA?

Regards,

Quy
