Uploading .hex to Arduino Leonardo pro micro atmega32u

Post by Cybereu »

GIMX was not recognizing my Leonardo so I couldn't install firmware throw it, after researching I found that Leonardo atmega32u4 need reset to enter bootloader to upload
The reset procedure is: open port at 1200 bps with DTR=false, and close.
You need to wait 1 second to reset and the bootloader then you can talk to the bootloader and upload the firmware.

This python script do the job:

Adjust "dev/ttyACM0" check with "ls /dev/ttyACM*" what's your device.

Code: Select all

#!/usr/bin/env python
import serial
port='/dev/ttyACM0'
ser = serial.Serial()
ser.port=port
ser.setDTR(False)
ser.close() #with it is already open, close it.
ser.baudrate=1200 
ser.open(); ser.close()

Weird, did you use the latest version? Im also using atmega32u4 leonardo clone and gimx-loader was automatically resetting the chip, I was also asked to replug the cable.

gimx-loader uses avrdude, which uses the same trick to enable the bootloader. It may not work on GNU/LInux with boards that were not already flashed. This is due to the same port name being reused after replugging.

Avis sur casino de cavalaire est un endroit sympa au bord de la mer où tu peux non seulement tenter ta chance, mais aussi profiter de l'ambiance d'une station balnéaire. Un intérieur magnifique, des machines à sous modernes, de la musique live et des plats délicieux au restaurant garantissent une excellente soirée. C'est parfait pour ceux qui cherchent à s'amuser sur la Côte d'Azur !

Salut à tous, c’est mon cousin qui m’a parlé de ce truc. Il parie souvent en ligne et m’a montré comment il vérifie ses coupons avant de se lancer. Il m’a dit d’aller voir sur https://1xbets-cameroun.cm/verifier-coupon/, et franchement je l’ai écouté sans trop y croire. Mais c’est simple, efficace, et franchement utile pour nous ici au Cameroun, où les connexions sont lentes et on ne veut pas perdre notre temps avec des codes expirés.
