Can burn .hex with Arduino Nano

[Chandler-Kluser]

I have sucessfully flashed a small blink (without bootloader) program using a LGT8f328p to flash another LGT8f328p using the specs and the wiring the instructions said to do.

But I could not flash using an Arduino Nano for that, repeating the same wiring and specs I used with the LGT8f328p flasher.

I am a bit worried because I have only one LGT8f328p with me, the another one I used I picked with a friend of mine who had gently lent me but I have sent It him back.

The sketch in the repo is supposed to work in an Arduino Nano, right? Or I can only be used with a LGT8f328p acting as a flasher?

I have also selected the Arduino IDE to flash my Arduino Nano as a LGT8f328p, with the RX_SERIAL_BUFFER_SIZE set to 250, but It didn't succeed either.

The avrdude command I am using is:

avrdude -u -c stk500v1 -p m328p -P /dev/ttyUSB0 -b 19200 -B 1.5 -U flash:w:"/path_to_hex_file"

*using the LGT8f328p flasher I only replace the /dev/ttyUSB0 for /dev/ttyACM0

and It's not working only with the Arduino Nano.

Hi ,

I have not try with Arduino Nano, but it should be no any difference. Accroding to the image attached, if it's the case of arduino nano, "Board" should be "arduino nano" like. "Arduino as ISP" is right. then, try to update target bootlaoder by start "Burn Bootloader"

P.S, don't forget to connect a 4.7Kohm pullup for SWD (pullup to VCC)

Thanks and best regards,

Before the shot was taken, I had already tried with the "Arduino Nano" board selected in the IDE.

About the resistor: I have tried with the LGT8f328p flasher and It worked with and without the resistor. I will try with the Arduino Nano, too.

w/o resistor

w/ resistor

If I solve the problem I will close this issue! Thanks in Advance

Kind Regards,
