Tool/software:
Hello,
Currently I am trying to debug my LAUNCHCXL2-570LC43 using XDS 110 External Debugger. It has J18 Header which is used for external debugging. I have connected JTAG TI14 Pins Header with J18 (which has 20 pins).
I have also linked Pin 8 and Pin 10 of J18 together and they are further connected to Pin 8 (GND) of JTAG Header. Similarly, I have linked VTref and nTRST pins as well.
I have given 3V3 external power supply to J1 pin 1 (+3V3/6.6C).
But when I debug my code using CCS then I get this type of error :
"Error connecting to the target:
(Error -2131 @ 0x0)
Unable to access device register. Reset the device, and retry the operation. If error persists, confirm configuration, power-cycle the board, and/or try more reliable JTAG settings (e.g. lower TCLK)."
When I checked VTRef using multimeter then I get 3V3 which verifies that Onboard debugger is successfully isolated. What I think is that I need to Isolate Voltage regulator as well. (I have also tried to provide +5V Dc voltage using +5V Dc Optional Jack on Launchpad but didn't work).
What could be the possible reason of it? Do I really need to isolate Voltage Regulator?
