Other Parts Discussed in Thread: CC3200

Hi:

I got this error message "Cortex_M4_0: Trouble Reading Memory Block at 0x20030008 on Page 0 of Length 0x4: Debug Port error occurred."

I have checked cc3200v1p32.cmd, seems memeory defination is ok:

    /* Application uses internal RAM for program and data */
    SRAM_CODE (RWX) : origin = 0x20004000, length = 0x14000
    SRAM_DATA (RWX) : origin = 0x20018000, length = 0x18000

Thanks

Hi Xiang,

Could you share the device part marking on the LP you are using? For ex., is it XCC3200HZ or XCC3200JR.

Also in the linker cmd file, the SRAM region is defined only upto 192 KB (ie 0x20030000). This is the case for XCC3200HZ devices. If your device is this, you will not be able to use/access beyond 192 KB.

Best regards,

Naveen

Hi Xiang,

Apologies for the delayed response. Maybe you have figured this out.

You have an ES 1.21 device. You will need to use the option CC3200_ES_1_2_1 for compilation and linking.

Best regards,

Naveen
