Hi,
<Phenomenon>
In the past, the debugger and target were successfully connected, but a connection error occurred immediately after loading the program, and the target could not be connected after that.
I did the following but it didn't work.
・Restart PC and CCS
・Reboot the target (control card & docking station)
・Use the Target Configurations file of another sample program
・Each switch setting of the control card has not been changed.
This error occurred immediately after loading a program that changed the GPIO input/output pin settings. I tried replacing it with the project file before the change, but it didn't recover.
<Error message>
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).
(Emulation package 9.2.1.00046)
<Equipment used>
Control card: TMDSCNCD280025C
Docking station: HSEC180controlCARD
CCS version: 9.3.0.00012
■ Question
What should I do first to try to isolate the problem?
Thanks,
Astro
