1 year ago Can you upload the hex file you're using?
When using a bootloader, the program needs to start at address 0x200, because the bootloader uses the first 512 bytes in the flash memory.

1 year ago The problem is that the code isn't compiled for use with a bootloader. If you look at how Intel hex files works, you can see that your program starts at 0x0000 and not 0x0200.
You need to compile your program with the bootloader option enabled in Arduino IDE.
BTW, are you using Arduino IDE or PlatformIO to compile your code?

1 year ago For this one I used Arduino IDE with following settings: Board: "ATmega4809" Clock: "Internal 16MHz" BOD: "BOD 2.6V" EEPROM: "EEPROM retained" Pinout: "Nano Every" or I use "48pin", does not change the outcome Reset pin: "Reset" Bootloader: "Optiboot (UART3 alternative pins)"
So how do I make the program start on 0x200 please? I thought that when I just choose the bootloader it will automatically start here, I can see that the hex file I sent in previous post contains the bootloader in the beginning...

1 year ago If I understand it correctly, the first lines are the bootloader and then the code appended starts on :2002000050C0000068C0000066C0000064C0000062C0000060C000005EC000005CC00000E0, which by the link you sent means address 0x200, right?

Also, I'd like to see the current fuse settings.
Use -U fuses:r:-:h to dump all fuses

When I switch from board ATmega4809 to Arduino Every and upload it using UPDI (Arduino Nano as jtag2updi), the sketch works and LED blinks.

1 year ago Now I did a test. I have tried to compile the code as for Arduino Every, took that one and manually created a .hex file with fuse setting for bootend 0x02. The code alone works, but as soon as the bootloader preceeds it, it does not work.

So you compiled your blink program with the Arduino Nano Every pinout and with a bootloader (UART3)? Was this uploaded using a UPDI programmer? is it the *with_bootloader.hex file that doesn't work?

1 year ago Sorry for confusion, by the way, I really appreciate your support, thanks for the immediate replies! Here are the steps I have done to get to this point: 1: I have modified the original Arduino Nano Every with ATmega4809 like this: https://content.arduino.cc/assets/NANOEveryV3.0_sch.pdf?_gl=1*17exlmw*_ga*MTk3NTMzOTE2MS4xNjQ2Mzk2ODUy*_ga_NEXN8H46L5*MTY3OTU2Nzc1MC4xMzQuMS4xNjc5NTY3NzYxLjAuMC4w
I have removed Q1 and Q2 to disconnect UART and UPDI between ATmega4809 and SAMD11. Then, I have added a serial resistor to UPDI with a value of 4k7. After checking the signal with a scope, I found out that UPDI does not work so I tried removing R19 (4k7 PULLUP on UPDI) and it started working. I did this after step 2, but if you have Arduino Nano Every and Arduino Nano to try this, I have summed it in here so it can be done at once.
Board: "Arduino Nano Every" Registers Emulation: "None(ATMEGA4809)"
And sketch with options using MegaCoreX with no bootloader:
Board: "ATmega4809" Clock: "Internal 16MHz" BOD: "BOD 2.6V" EEPROM: "EEPROM retained" Pinout: "Nano Every" or I use "48pin", does not change the outcome Reset pin: "Reset" Bootloader: "No Bootloader"
will result in two different hex files.
So I took the original work ing blink sketch hex compiled with default Nano Every options Blink_test.ino.hex.txt , then I took the bootloader itself Optiboot_mega0_UART3_ALT_115200_A7.hex.txt and combined the into one hex (sorry I was using the dumps which were written in shorter code, because I needed to change the checksum for each line). I have just appended the working code and changed the starting address to 0x200 and the for every next line I changed the address accordingly and also the checksum, so it looks like this test_with_bootloader.hex.txt . However, with this one, the bootloader works (Iam able to upload it using the serial3, but it will not blink the LED). My theories are these:
I am using an FT231X as a USB-Serial adapter for ATmega4809, so I might try changing it to CH340 or something like that if it solves the issue.

1 year ago I managed to get it to work.
I'm using the built-in jtag2updi programmer on the Nano Every, since I didn't want to modify the board. I'm using stty to trigger a "1200bps touch" in order to enter "jtag2updi mode". I've also connected a USB to serial adapter to UART1 ALT (Nano every pins 0 and 1).
I've build the latest Avrdude on my computer, which lets me connect the DTR/RTS line on my USB to serial adapter directly to the Nano Every reset pin without the need for a capacitor. This feature will be available in Avrdude 7.2.
(I know this because I'm one of the active Avrdude developers at the moment. Pro tip: Play around with Avrdude terminal mode in Avrdude 7.1 and read the docs. It's an incredible tool that gives you r/w byte access to any memory, and it's also very powerful. Data can also be piped into Avrdude terminal mode)

1 year ago I have tried your solution, connected the programmer to UART1 alt pins and it works. So I think there must be something wrong with using UART3 ALT pins for programming for sure. Can you please try to reproduce my steps? You can just remove the two dual transistors and solder RX and TX to the exposed pads. For some reason, it is not working. Also, I would like to ask - how to get the serial communication working now? Serial.begin and Serial.println will dimm the LED when I try using it on pin D7 (PIN_PA1) and Serial1.println() doesnt print anything...

1 year ago Hello, so I am currently using it as per your information. For anyone reading this in the future I will add some info: Use UART1 alternative pins for bootloader, also use the same for RX/TX for USB serial console. However, in the code, when using Serial.print(), use Serial1.print(); to get it working. for init, you need to use Serial1.swap(1); . When you want to use same SPI pins as on Arduino Nano Every with mega4809, you need to write SPI.swap(2); in the beginning of your code.
Also I have two last questions for @MCUdude :
In the end, I would like to thank both of you guys responding there in the thread for the information an in the future, if there is a possibility, please try to test the UART3 alt pins for bootloader - I am still not able to get it working.

As you can see here, -carduino means that you're trying to write fuses using the bootloader. This is impossible.
The reason why modifying this core for "custom" Nano Every use is because I had to do some tradeoffs in order for the IDE to deal with the 1200bps touch thing in order to trigger JTAG2UPDI mode in the on-board programmer.
I recommend using the Nano Every pinout with an unmodified Nano Every, and for everything else, use one of the "standard" pinouts, as these are much easier to deal with in terms of uploading using UPDI or using a bootloader.
When will be the avrdude 7.2 ready with implementation for the DTR/RTS to reset pin ready?
Avrdude 7.2 will let you connect the DTR or RTS pin on the USB to serial adapter directly to the reset pin on the AVR without a capacitor in series. Nobody knows when Avrdude 7.2 will be released, but given how few bugs have been discovered in 7.1, I don't expect a release anytime soon. It will probably happen in 2023 though.
How does the HW implementation of DTR/RTS pin to MEGA4809 RESET pin look like? Is it just straight connected, or is there any pullup/pulldown/cap?
Have a look at the "Minimal setup" schematics: https://github.com/MCUdude/MegaCoreX#minimal-setup
I'm not sure why I haven't added it, but a 10k pullup resistor on the reset pin on the ATmega4809 is also good to add.

1 year ago Similar discussion of Nano Every here.
I was able to use the Optiboot-x bootloader provided by @MCUdude last time on the Nano Every (same here as I also do not want to change it). I have not tried it for a while though.
Reference: bootloader hex files by @MCUdude for Nano Every and Nano 4808.
``Hello, I am trying to get ATmega4809 on Arduino Nano Every working with serial programmer. Thing I have done:
So my issue is - I can burn bootloader via Arduino Nano to the ATmega4809. When I dump the memory to a file, it is exactly what the bootloader hex from your code looks like. When I try uploading through serial (FT231X connected to mega4809 on Serial3 alt pins), it uploads just fine, reads just fine but the code simply does not run. I checked the fuses, dumped the hex (bootloader is still here, tried to upload also with no bootloader, whatever...). When I tried a sketch as simple as this:
`#include
bool test;
void setup()
{
pinMode(5,OUTPUT);
}
void loop() { delay(500); test = !test; digitalWrite(5,test); }`
, it simply will not do anything. Tried using serialPrint, SSD1306 display, also nothing. Also I tried uploading with PlatformIO on VScode, it deletes the bootloader but the sketch gets uploaded, also does not work. When I purposefully "messed" the pin operations up in the code, on some versions the LED lit up with a very low current (I guess something got really wrong). Is there anything I forgot? I tried also not using the Arduino pinMode and digitalWrite functions, I just set the registers directly, with also no luck. Is there anything I am forgetting from the HW point? Do I need to add some resistors, etc? It drives me crazy as I have already written a long code that works on Nano Every, but I want to use my own boards and I do not want another chip (SAMD11) here. Thanks in advance!
