I started a project with the Atmega328PB and subsequently found out that there was not enough memory so decided to use the Atmega4808.

So, I bought a few chips and made an experimental board with a minimum of external elements (as in the picture).

I'm using the Popolulo USB USB AVR v2 programmer and trying to connect it to the board via ISP or UART were got a strange signature:

c:\>avrdude -c stk500v2 -P COM5 -b 115200 -B 1 -p m4808 -F

avrdude: stk500v2_program_enable(): program enable instruction not defined for part "ATmega4808"
avrdude: initialization failed, rc=-1
avrdude: AVR device initialized and ready to accept instructions
avrdude: Device signature = 0x656570
avrdude: Expected signature for ATmega4808 is 1E 96 50

avrdude done. Thank you.

So far, I told ISP can not be used for this purpose and follow the https://github.com/ElTangas/STK2... have programmed one Adruino nano 328bp and connect to my tiny 4808 board via UPDI pin and got the same result:

c:\1\>avrdude -v -c stk500 -P COM4 -b 57600 -p m4808 -F

First welcome to AVRFreaks!

So from the above question, I take it you did not read the data sheet for the M4808, as on page 1 it says:

Which tells you it does not use ISP for programming, but rather UPDI, so you will need a programmer that supports UPDI to burn your flash.

One such programmer is the atmel ICE, there are others but are not as simple to use.

There are lots of other differences between the new xtiny chips and and the older mega chips that you will need to learn as well, it is not a simple port.

Take it one step at a time, and you will get there. Have you considered using another mega chip(atmega2560) with more flash? Or perhaps writing more compact code to fit it into M328.

Hi Jim,

Many thanks for your warm welcome and your quick feedback.

I saw what was written in the datasheet, but I interpreted it as saying that UPDI can be used in addition to standard methods such as ISP or UART.

I chose the m4808 because it has a ULP RTC built-in and doesn't need many external elements were planning to use ESP32 for a subsequent firmware change over Wi-Fi so need a way to do that w/o using a special programming tool.

Anyway, I tried with STK2UPDI as described in https://hackaday.io/project/134831-atmega4809-developing-board-project/log/144552-how-to-start-configurable-custom-logic-on-atmega4809 but got same signature which on top of that is floating - seems reading a dynamic data instead of chip signature.

I've been playing for a few days now and I'm fully blocked. Obviously there is some mistake in the protocol, but I have no attempt to do so (seems after over than 10 years as a manager, my developer experience is gone :)

Once again - many thanks to you!

Dave

fyi, Arduino Uno WiFi Rev 2 shows UPDI from the ESP32.

That's because that program is basically deprecated and not compatible with the mega AVR-0 series. I wrote a more up to date programmer that you can get here: https://github.com/ElTangas/jtag...

Hi El Tangas,

Many thanks for your replay.

I'm using Wemos CH340G -> A-Star 328PB with an external 8MHz oscillator (PD6) -> pin 27 (UPDI) on the simplest mega4808 board possible. I also added a 10uF capacitor to the RST-GND on 328PB board as suggested at https://github.com/SpenceKonde/m... - believe is adding a pull-up delay after powering up the device.

Then I thought my self I might have damaged the chip during soldering, so connected it to an original ATmega4809 Xplained Pro but ... all same.

Do you have an idea what could be wrong?

Thank you,

Dave

Hi folks,

Many thanks for your support. Finally, I caught the problem:

1. The board CPU frequency was #define F_CPU 16000000U where in my case is 8MHz

2. It seems to work on 19200 baud rate only, at least in my case.

Normally, jtag2updi defaults to 115200 baud, which is fine if the programmer MCU is running @ 16MHz, but too fast for a 8MHz device. In my tests, in general 8MHz programmers will work @ 57600 baud, but it's not totally unexpected that you need to go even lower.

edit: BTW, the 10uF cap is not really needed. I wrote that in the jtag2updi documentation due to a misunderstanding on my part on how avrdude uses the DTR line for different protocols. Unfortunately, SpenceKonde has propagated my mistake, I really need to correct that one of these days...
