Hi All,
I wonder where Digikey got their chips? I wonder if the chip OEM can shed any light at whether these are really their chips or not.
Sounds VERY curious to me.
I bought some 'new' 'sealed' relays years ago that were apparently returned from someone who did bubble testing. Many had water inside. Caveat emptor.

Hi all
It seems we have some relatively large proportion of problems with the
latest batch of blank ATmega328 chips. Actually these are the large stash of
ATmega328's I bought from Digikey while I was in the US for Dayton
FDIM/hamvention. We are now finding that in each tube of 14 chips, the 7'th
chip is always a failure. How weird is *that*? Always chip number 7 of 14...
I was skeptical... but it has happened now many times...
Now with the T1.00f firmware update a few days ago for the QCX, on flashing
the chip the firmware first checks everything then activates the beeper on
our programmer here. So we now have a built-in confirmation that the chip is
Ok and now we can reject any problem chips before sending them out.?
In the meantime if anyone has an issue with a chip then please contact me
off list, I will help you sort it out (if you have an AVR programmer) or
send you a new chip (if you do not have an AVR programmer).?

Carl, do you have an arduino?
If so look here:-?
If not, beg borrow or buy one then look here Hi.?

Forget Avrdude..?
It just over complicates things.?
Download AVRDUDESS which is a more modern piece of programming
software and then wait for Hans to get in touch with you.?

I read Bernie's response about .eep and .hex files,
started doing some searches. There seem to be 5 areas on
the chip that can be programmed
flash,
eeprom,
hfuse,
lfuse and?
efuse
There are 'avrdude' programmer commands on this page?to
read and to write each of those five areas.? If we need
all five files (.eep, .hex, .bin or whatever, the
extension is probably just a convenience) to reflash a new
controller then we should add those to the firmware
archives, with some QRP specific instructions.
