It works now, thank you!! It did require connection of VCC to the JTAG for successful connection, and then ready to go!

Thank you for update

I see elsewhere on internet that people connect VCC as well for Segger J-link.
This is not needed for Olimex ARM-USB-OCD-H.
Both ESP32 DevKitC and ARM-USB-OCD-H have their owe power supply though USB.
Just GND and five JTAG signals is all they need,

Congratulations! I'm getting the same "all ones" error you had before, but I'm using TUMPA. Did you just make the VCC connection to get it to work? I've already got VCC connected to VTAR but I'm still getting the "all ones" error.

my goodness this is spectacular content, thank you! I almost want to head back into the office tonight and explore, this is taking effort to resist..

looking forward to investigating tomorrow, so clearly described & illustrated. Is this new content, I didn't find this last week!
