Game Input MultipleXer

Hi
I have problem with Arduino Pro Micro to upgrade a new frimware. When i bought uC i upload hex in Arduino buldier by usb. Now upload by usb is unavailable so i buy usbasp and try upload frimware 5.0 but when i click USBASP in Arduino Builder i have error "No serial port is accessible" when i want upload hex by avrdude its immposilbe becouse digital signature for Atmega32U4 is wrong

Anyone can help ?

Hi,
Did you powered the target?
Please post a photo of your wiring.

ofc uC is powered

Is your USBASP programmer 5V tolerant?
What voltage do you supply to the target?
Where did you buy the USBASP?

I buy in https://www.sklep.atnel.pl/pl/p/Program ... culator/39
Its very good usbasp in Poland, its not cheap chinese usbasp

I guess the on-board switch is used to select the voltage level (3.3V or 5V).
It should be set to 5V. Also make sure to supply 5V to the target.

There is no switch voltage is automatic
But thanks for Kakiharasama. He give me info about switch to bootloader in arduino click 2x RST with GND and fast press enter to loading hex. Now i have problem with GIMX 5.0.

I use ft232rl its work perfect withx GIMX 3.5 on PS4
I try unlisntal usbDk 1.0.6 and install again but still the same

Uninstall USBDK 1.0.6 and try USBDK 1.0.4.

Could you please try with GIMX 4.3? You can keep the 5.0 firmware.
