Wear Leveling on DataFlash. Buy from the Microchip Store. I realized after that the problem may have been that I set the bits for external clock rather than crystal oscillator but even with using an ATTiny to generate a 1MHz signal to the proper pin on my Mega, I still get nothing. As I’ve never used the device, I’ll defer to the many datashewt threads where others have posted problems and solutions attmega644pa AVR fuse settings.

But, this is a different chip slightlydifferent fuse settings, and a different programmer, so I say we let it stand And I don’t have the rep to flag it. Any ideas as to why the chip is unresponsive?

I hope we can offer you a warm welcome, but your question might be a dupe. Upgrading the Flash memory using a U-Disk. Sign up using Facebook. Calibration of the internal RC oscillator. The AVR device connects to the STK using an innovative routing and socketcard sandwich atmwga644pa, which routes the signals from the device to the appropriate I have been programming an ATMegaPA with avr-gcc and avrdude on linux for a little datasheer with no problems.
