Other Parts Discussed in Thread: SYSCONFIG
Hi,
I am trying to read some registers on the Cortex M3 ISS core in a DM8147 using CCS 5 so I have created a GEL file to do this.
When I connect to the Cortex M3 ISS and load my GEL file then it doesn't seem to be possible to read the register values. All my 32-bit register reads returns the value 0xBAD0BAD0.
Here is a couple of lines that illustrate what I am trying to do:
#define ISS_ISP5_SYS1_BASE_ADDR 0x52010000
#define ISP5_REVISION (ISS_ISP5_SYS1_BASE_ADDR + 0x0000)
#define ISP5_HWINFO1 (ISS_ISP5_SYS1_BASE_ADDR + 0x0004)
#define ISP5_HWINFO2 (ISS_ISP5_SYS1_BASE_ADDR + 0x0008)
#define ISP5_SYSCONFIG (ISS_ISP5_SYS1_BASE_ADDR + 0x0010)
#define ISP5_CTRL (ISS_ISP5_SYS1_BASE_ADDR + 0x006C)
#define ISP5_PG (ISS_ISP5_SYS1_BASE_ADDR + 0x0070)
#define ISP5_PG_PULSE_CTRL (ISS_ISP5_SYS1_BASE_ADDR + 0x0074)
#define ISP5_PG_FRAME_SIZE (ISS_ISP5_SYS1_BASE_ADDR + 0x0078)
hotmenu ISS_READ_PG_SETTINGS()
{
GEL_TextOut("\t **** Reading ISS PG in progress......... \n","Output",1,1,1);
GEL_TextOut("Read ISP5_CTRL addr %x=%x\n",,,,,ISP5_CTRL,RD_MEM_32(ISP5_CTRL));
GEL_TextOut("Read ISP5_PG %x\n",,,,,RD_MEM_32(ISP5_PG));
GEL_TextOut("Read ISP5_PG_PULSE_CTRL %x\n",,,,,RD_MEM_32(ISP5_PG_PULSE_CTRL));
GEL_TextOut("Read ISP5_PG_FRAME_SIZE %x\n",,,,,RD_MEM_32(ISP5_PG_FRAME_SIZE));
GEL_TextOut("\t **** Reading ISS PG is DONE **** \n","Output",1,1,1);
}
I then get the following output:
Cortex_M3_ISS: Output: **** Reading ISS PG in progress.........
Cortex_M3_ISS: GEL Output: Read ISP5_CTRL addr 0x5201006C=0xBAD0BAD0
Cortex_M3_ISS: GEL Output: Read ISP5_PG 0xBAD0BAD0
Cortex_M3_ISS: GEL Output: Read ISP5_PG_PULSE_CTRL 0xBAD0BAD0
Cortex_M3_ISS: GEL Output: Read ISP5_PG_FRAME_SIZE 0xBAD0BAD0
Cortex_M3_ISS: Output: **** Reading ISS PG is DONE ****
What am I doing wrong here?
Best regards,
Karsten
