#191 Arduino Nano ESP32: Can't get started

[Kenneth Martin]

OS: Ubuntu 22.04, installed apimage,
serial: /dev/ttyACM0
/etc/udev/rules.d/99-usb-serial.rules:
SUBSYSTEMS=="usb", ATTRS{idVendor}=="2341", ATTRS{idProduct}=="0070", GROUP="dialout", MODE="0666"
after reboot
lsusb: (relevant line):
Bus 001 Device 002: ID 303a:1001 Espressif USB JTAG/serial debug unit
Note: ID changed at reboot; update udev rule and reloaded udev and triggered.

It compiles (took a lot for this to happen).

Upload fails:
dfu-util: No DFU capable USB device available
Failed uploading: uploading error: exit status 74
(no idea what 74 signifies).

Documentation: inadequate especially when things don't work. For example can't find any documentation on how to start "arduino-ide" in linux? where is apt kept? doing a ps aux shows a mess (see below at bottom).

Excuse font, don't know how to revert to default.

Exact version of dfu-util: from distro? self-built? git revision?
Can't answer without instructions, but best guess is:

ls /home/martin/.arduino15/packages/builtin/tools/dfu-discovery
. .. 0.1.2

Question: isn't the whole idea being that getting blinky to work doesn't require hours and hours of an expert? Everything else I hooked up to USB serial worked out of the box and had reasonable documentation.

Here at the dfu-util bug tracker we only deal with dfu-util itself, not the Arduino IDE. Arduino bundles their own modified version of dfu-util. Anyway, I notice in the ps aux output that you are running a "nightly" snapshot "arduino-ide_nightly-20240229_Linux_64bit.AppImage". Maybe you should try a stable release?

This is the the problem that dfu-util sees (74 is just a code for this):
dfu-util: No DFU capable USB device available
So the Arduino IDE hasn't successfully made a DFU device available for dfu-util.
