Other Parts Discussed in Thread: UNIFLASH, AWR2944

in sop[2:0]=101 UART Boot Mode，I use python script to download these three image: sbl_uart_uniflash.release.tiimage, sbl_qspi.release.tiimage, ti/utils/ccsdebug/awr2944_ccsdebug.appimage
in sop[2:0]=001 QSPI Boot Mode, I open Code Composer Studio,create a 2944.ccxml target configuration to debug myself app code, I can just connect cotex_R5_0,the other two core,I can not connect well.

So.my problem is that How to connect these core well and to debug myself app code.

By the way, I changed the SDK to mmwave_mcuplus_sdk_04_03_00_01,and use the same way to flash images, I can connect coretex-r5_0 and dsp (not connect coretex-r5_1). When I use mmwave_mcuplus_sdk_04_02_00_02 ,I can just connect coretex-r5_0，so please help me with this problem.

Thanks!

Hi,

In AWR2944, the device operates in lockstep mode by default. Meaning the second R5 core will be following the first cores execution in lockstep and the second R5 core cannot be used/connected to by the user (Only R5F_0 and DSP core can be connected). This is as per the safety requirement and is expected when the device is running in lockstep mode. Operating the device in non-lockstep mode (i.e dual core mode) is not recommended in AWR2944.

Thanks.

Hi,

yes, you can only connect to r5f_0 and DSP when ccs debug is running.
