Original question:

CCS/TMS320C6678: PRSC module failed to write to a register

CCS/TMS320C6678: TMS320C6678 Error with Emulator reset

Part Number: TMS320C6678

Tool/software: Code Composer Studio

Dear,

We have used C6678 in our custom board with 14 pin JTAG connector, in which we are facing the following error when system reset is issued: 

C66xx_0: Failed System Reset: (Error -6311) PRSC module failed to write to a register. (Emulation package 7.0.100.0) 

C66xx_0: Trouble Halting Target CPU
C66xx_0: Trouble Reading Register PC
C66xx_0: Trouble Reading Register ControlRegisters.CSR
C66xx_0: Trouble Reading Register ControlRegisters.CSR
C66xx_0: Trouble Reading Register ControlRegisters.CSR
C66xx_0: Trouble Reading Register ControlRegisters.CSR
C66xx_0: Trouble Reading Register ControlRegisters.CSR
C66xx_0: Trouble Reading Register ControlRegisters.CSR

We are able to connect and load the application on to DSP and execute, We are able to Boot from NOR flash on EMIF also

We have verified the DSP clocks and reset timings of DSP, All are good,

Once RESET is issued, probed the RESET STATUS and its togling, but emulator is not able to proceed with further activities.

If the emulator is removed from connector and connect it back without power cycle, then emulator is able to proceed with the further activities

Could you help us to resolve the issue..

Awaiting for you reply...!

Thanks in advance

    Hi Nagendra,

    I assume you already checked the troubleshooting link desouza provided in the other post.

    Based on the Emulator package version, it looks like a pretty old version of CCS is being used. Would it be possible to retry with the current latest version (CCS 10.1)?

    Thanks
