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