AWR6843AOP : Error while trying to load program

Hello,

Two things I want to confirm:

1. Have you flashed the correct debug binary file to the device? In order to use CCS Debug and load the DSP core, it must be initially be flashed with the debug binary which can be found in C:\ti\<mmwave_sdk_version>\packages\ti\utils\ccsdebug. For AOP make sure you flash the 6843 one

2. After flashing this binary, have you set the device back to functional mode? If the device remains in flashing mode, then the memory cannot be read and the error you see is given https://dev.ti.com/tirex/explore/content/mmwave_industrial_toolbox_4_11_0/docs/hardware_guides/evm_setup_operational_modes.html

I have flashed with debug binary and returned to the functional mode. There is no problem with loading DSS code, but I can't load the mss to the Cortex R4 core.

Hello,

Can you try flashing premade 6843 .xer4f and .xe674 files to your device? You can find the two files in the SDK folder shown below:

C:\ti\mmwave_sdk_03_06_00_00-LTS\packages\ti\demo\xwr68xx\mmw.

One thing I have noticed in your error log is that the project name is 68xx but the xer4f file you are using has 64xx in it.

Thanks for your replies but it didn't solve my problem:

Cortex_R4_0: Trouble Writing Memory Block at 0x0 on Page 0 of Length 0x3c: (Error -1065 @ 0x0) Unable to access device memory. Verify that the memory address is in valid memory. If error persists, confirm configuration, power-cycle board, and/or try more reliable JTAG settings (e.g. lower TCLK). (Emulation package 9.7.0.00213) 
Cortex_R4_0: File Loader: Verification failed: Target failed to write 0x00000000
Cortex_R4_0: GEL: File: C:\ti\mmwave_sdk_03_06_00_00-LTS\packages\ti\demo\xwr68xx\mmw\xwr68xx_mmw_demo_mss.xer4f: Load failed.

Hello,

Let's take a step back, could you try running Out of Box demo without debugging mode? So without worrying about uploading the .xer4f and .xe674 core binaries separately, you should flash the main Out of Box Binary via Uniflash and test the Out of Box demo visualizer to see if we get proper functionality from this demo. You can find the Out of Box demo user guide in our TI Resource Explorer Industrial mmWave Sensor Toolbox here: https://dev.ti.com/tirex/explore/node?a=VLyFKFf__4.11.0&node=APR4NbV00IeYkywyV9UT7g__VLyFKFf__4.11.0

Let me know what your results are.

Hi, 

I flashed my board successfully with "multi_gesture_demo_68xx_aop.bin". Then put back to functional mode. When I connect to the board there is no functionality on the visualizer. So I connected to config uart with serial monitor and made my board power on. There is no sign of activity on uart. 

Hello,

For your 6843AOP device, could you please try this specific binary with this specific visualizer.

Binary:

C:\ti\<mmwave_sdk_version>\packages\ti\demo\xwr64xx\mmw\xwr64xxAOP_mmw_demo.bin

Visualizer:
