I am still able to connect my Arduino Uno without any problems. Any help or advice would be appreciated.

To get boards with SiLabs drivers to work at all, you have to use the older v4 driver from the Legacy MacVCP Driver folder in the same download.

Symptoms are: SiLabs port appears in Arduino menu and when upload is pressed, serial communications start, but avrdude errors out with messages about incorrect responses and the upload does not finish.

Fix: roll back to SiLabs 4.x series drivers.

Side note: Im sorry to say for Adafruits part in this, the board documentation is not up to your usual high standards.

Is selecting Metro from the board menu the right choice for the Metro Mini) I hope youll consider paying someone to write up a nice HOWTO page for the Metro Mini like weve come to appreciate for other Adafruit products.

Because as it is now, for this amount of trouble and misleading documentation I might as well buy TI dev boards and get the same amount of torture but for less money.

Slilabs 2102 10.10.5 Install V5 I

Any chance you could help with the steps to uninstall v5 I believe I installed v4 from the Legacy folder, but I dont see anything in the Port menu from Arduino.

Also, as you mentioned its confusing to me if I use Metro from the board drop down or Uno like it mentions on the Metro Mini Adafruit page.

I think we found that the first run only uninstalled the current driver, and it took another pass to actually reinstall.

Thanks, SiLabs.) You may also need to reboot, not positive though.

Cant hurt. We are using Metro as the board type.

Note that the serial port wont show up under the usual tty.usbmodem nomenclature, it will be something with Slab in the name.

It appears to be a problem with the SiLabs 5.0 driver that was released on August 3, 2017 (only a few days before this initial report).

This driver added GPIO support, but looks like it broke regular serial operation as people on the SiLabs forums have reported problems with other devices.

Do note that the SiLabs driver page claims the v4 driver is the latest, and the release notes linked from the page are out of date.

The correct release notes are included with the driver download.

This affects all versions of macOS (we were running a class and some people had macOS 10.11, and Im running macOS 10.13 Beta), as long as the 5.0 driver is used.

It likely affects everything that uses the CP210x, not just the Metro Mini.

Thanks for putting together the tutorial Any chance you could update the product pages to indicate this driver issue These kinds of issues are quite frustrating since troubleshooting them is less than obvious.

Barely relevant side note: personally I prefer boards that use a programmed Atmega16u2 for USB-UART conversion, like the current Uno R3, mainly because this allows use of the OS-provided USB-serial driver, and writing a good USB-serial driver for Mac is extremely difficult -- see.

CP210x driver is no longer relevant.

This also allows doing fun stuff like flashing the Atmega16u2 with USB-MIDI firmware:.

I am aware that increases BOM cost though.) Relevant SiLabs threads:.

Slilabs 2102 10.10.5 Full Arduino Uno

Though I do wish someone made a full Arduino Uno clone (with both AVRs) in a compact package:) On the SiLabs side, looks like they finally acknowledged the problem and rolled back the Mac driver (the download page claims v5 but the downloaded file is v4).

See. trueM4416.

It was helpful to look at the full write-up on the Metro Mini to be sure that I am following the instructions correctly, but I still cannot get my macbook pro to recognize the metro mini.

I have downloaded and installed the FTDI VCP drivers and the SiLabs v4 drivers.

I have also tried what I have seen on some other forums about installing the drivers twice in a row to no avail.

I have restarted my computer and have searched for the serial device through terminal.

The green LED (ON) is on and the red LED (L) is blinking while plugged in.

I am still able to connect my Arduino Uno without any problems.
