Part Number: AM2732
Other Parts Discussed in Thread: TMDS273EVM

Tool/software:

I am using TMDS273EVM, rev C. In this Boot pins I have kept in Development mode SOP0 - short, SPO1-short and SOP2-open. I have installed SDK and I have imported examples like blink LED/hello world. I am using CCS20 version. Code for R5_0 core, is running and LED is blinking. But example code imported for DSP core is problem. Connection itself not happening.

Following error is appearing

Texas Instruments XDS110 USB Debug Probe/C66xx_DSP Error connecting to the target: (Error -6305) PRSC module failed to write to a router register. (Emulation package 20.0.0.3344)

Hello Jagdish,

to run in development bootmode the board needs to run initialization scripts that are loaded in the R5 core by default, trying to connect to the C6 core without first waking up the R5 core will result in this error.

Can you please try to connect to the R5 first and then try to connect to the C6 DSP?

Best,

Daniel

Thank you Daniel for the reply.

I have falshed sbl.null.debug.tiimage and with this QSPI boot mode, I am able to connect and run DSP examples.
