Unconnected AVCC pin in ATmega644P
[Solved] Sorry for the delay in reply. There was a soldering issue in the jumper connecting AVcc and Vcc, hence it was essentially floating.   However, I realized that there...

Unconnected AVCC pin in ATmega644P
joeymorin: How have you determined this?  Multimeter?  DSO?  500 MHz probe on 4 GHz DSO, at 20 us/div time base. Checked with faster resolution also.  ...

Unconnected AVCC pin in ATmega644P
This post can be a new thread but I want to retain the history. 1. Now AVcc is firmly shorted with Vcc 2. BOD is set at 1V8 3. Vcc is 3V3 4. Its a mega644PA, with external xtal 11...

JTAG resets even if JTAG is disabled!
Solved! Apparently it was a noise issue, in which the noise was coupled to AVR through GPIOs - through the clamping diodes back to Vcc. When Vcc went haywire, periodic JTAG reset...
