Error connecting to target (Error -1065)

Hello,

I have a problem connection to a specific core on my target. I am using CCS V 6.0.1, Spectrum Digital XDS650V2 JTAG connector and a TDA3x board. After launching the target configuration I have 5 cores on the target that I can connect to (2x Cortex_M4_IPU, 2x C66xx_DSP, 1x ARP32_EVE). Connecting to the DSP and IPU targets works fine, but when I try to connect to the ARP32_EVE core, following error appears in the console:

CS_DAP_DebugSS: GEL Output: --->>> TURNING ON L3_INSTR and L3_3 clocks required for debug instrumentation
CS_DAP_DebugSS: GEL Output: ---<<< L3 instrumentation clocks are enabled >>>> ---
ARP32_EVE_1: Trouble Reading Memory Block at 0xc0000000 on Page 0 of Length 0x7ff0: (Error -1065 @ 0xC0000000) 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 5.1.636.0)

Could anyone please help me?

Thanks in advance,

Best regards,

Moritz Steinberg

    Hello Moritz,

    I don't have your exact target but I do have something very similar and I am able to connect to the EVE cores using a similar setup. These devices can have a bit complex startup so can you explain in detail the steps you are doing (ex - connect to A15 first and then run GEL function to initialize other cores, etc...).

    Also, what is the JTAG TCLK setting you are using? It seems like the below is the best for stability:

    Thanks
