Sketches run at very slow frequencyu after uploading with Atmel ICE on ATmega328p

PlatformIO IDE

Hi,
I have been programming smd 32 pins atmega328p’s for a while and everything worked perfect until I might have misclicked or misplugged something tonight. It is chaos. I manage to upload, but my upload times are super slow.
Here is a verbose upload

avrdude done.  Thank you.

I am not sure what caused the problem. It is not just the chip, because I get the same problem for every new chip I try to upload to. It is either my platformIO setup with fuses or whatever that changed or my atmel ICE itself (maybe its broken?) I have 3 ideas.

  1. I had my atmega and everything hooked up at 3v3 and had an I2C LCD. SDA and SCL were at 3v3 but I decided to plug the VCC at 5v. Maybe the SDA and SCL pins of the LCD at 5v bugged something on the chip or even on the atmel ICE?

  2. Maybe I clicked on set fuses and something changed in the code/ICE

  3. Maybe it has something to do with that safemode in my upload script. I do not recall seeing this before.

Here is my .ini when uploading with ICE: I added the two last lines after the bug in hope it would resolve but no. (Anyway [env:ATmega328P] doesn’t even recognize oscillator = external)

[env:ATmega328P]

platform = atmelavr

board = ATmega328P

framework = arduino

upload_protocol = atmelice_isp

upload_flags = -e

upload_port = usb

board_build.f_cpu = 16000000L

oscillator = external

Also, is there memory on the atmel ICE? Like does it save how to set fuses when it uploads or it is entirely up to PlatformIO? Im just really scared I broke my ICE. Its too expensive to buy a new one… Thanks!

avrdude is telling you the fuse settings… it looks like you haven’t set the fuse settings so it’s still using the factory default (i.e. internal 8mhz oscillator).

http://www.engbedded.com/fusecalc?P=ATmega328P&V_LOW=0x62&V_HIGH=0xD9&V_EXTENDED=0xFF&O_HEX=Apply+values

Since you were trying to set F_CPU to 16Mhz… I take it you’re using a external 16Mhz crystal, and the standard Arduino Uno fuse values should suffice?

http://www.engbedded.com/fusecalc?P=ATmega328P&V_LOW=0xFF&V_HIGH=0xDE&V_EXTENDED=0x05&O_HEX=Apply+values

As far as the oscillator parameter, it looks like the documentation needs an update, as it neglects to mention those parameters start with board_hardware. … ie. board_hardware.oscillator = external.

I don’t think the Atmel ICE has any memory as such… it’s not like a Pickit2 that can self-program MCUs … it’ll only set fuse values, etc to whatever you specifically instruct it to.

avrdude: safemode will always have been there… it’s just an indication of what the current fuse values are, whilst letting you know it hasn’t touched them.

Thanks ! I f found the solution with your link and explained it on a post where I detail how to work with atmel ICE on PIO. It was a fuse problem, I just dont know why my fuses changed randomly after weeks of use (maybe I clicked on set fuses accidentally) Thanks again for your help.

Fantastic! :slight_smile: I’ll have to bookmark that page as a reminder next time I drag my Atmel ICE out and have to start scratching my head trying to figure out why it won’t behave! :wink: I’ve had more luck with the much cheaper USBAsps, but sprung for a genuine Atmel ICE since I wanted have the option of doing debugging. I’m now starting to think I should have waited a bit longer, as it looks like the PICkit 4 will have AVR support (it already has SAM support) and may also support high voltage programming / reset… making it far superior (and cheaper!!) than the ICE. Ah well… maybe an excuse to get another programmer? :laughing:
