Arduino Nano with fried USB?

Hardware
1

Hello,

It would seem that my first Nano is fried before even running a program.
It gives me the following error:

avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x00

I have tried it with two USB cables (hard to find, these mini-USB cables), and it's the same.

But it's probably not completely fried. A script is executing, making one LED blink every second. So I wonder: is it possible to program it in some other way? Ideally, in a way that does not cost more in HW than the Nano itself? A do have an Arduino Uno and two Mega, plus an ESP32. Can they be used as programmers for the Nano?

D.

There are two boot loaders for the Nano, go into tools and select the other, that should make it work. The blinking LED is the default program loaded into the Arduino. That indicates that it is probably OK.

What would be the name of these bootloader programs? The Arduino tools, even arduino-cli hide the calls to other programs, and it's difficult to understand what the full compilation process does.
BTW, I have just installed the Arduino IDE (in addition to arduino-cli) and it doesn't detect the board.

If the Arduino IDE doesn’t see the Nano, I would check to make sure that the correct computer drivers are loaded for the Nano’s USB serial IC.

Other cards work well: Uno, Mega, and an ESP32. On the other hand, the Arduino is correctly identified as a USB device when I do the Mac equivalent of lsusb:

+-o USB Serial@02120000  <class IOUSBHostDevice, id 0x100006a33, registered, matched, active, busy 0 (52 ms), retain 27>

Yes. And those other boards have a different IC device that provides the USB connection. The official Arduino Nano uses a FT232 IC and Mac computers require the correct drivers if I recall correctly.

What brand Nano do you have? When it is connected to your computer, under Tools in the Arduino IDE, do you have the Nano selected as the board? Do you see the Com port for the Nano? Is it selected?

I realize that some of my questions are rather basic, but the more detailed response you provide, the easier it will be to understand your issue and help you figure this out.

Ok, I think you may have found the cause of my problems. My arduino nano uses the CH340 chip, and therefore the FTDI drivers no longer work. Thanks a lot for helping me solve the mystery. Thanks.
