Metro mini not recognized in Arduino IDE

Post by booss »

Hi,
I bought a metro and a metro mini but when I plug the mini, it won't show as the big metro is under "Port" in Arduino IDE.
I have the drivers installed, checked with another USB cable.
When I plug the USB cable, the red LED is flashing quickly then pulsing but the serial device is not showing in /dev/cu.*
Is it possible the board is dead ?
Thanks for your help.

Hi, thank you for your response.
I meant my trinket pro instead of my metro mini (both metro works but not the trinket).
I will try to re-program the bootloader with my leonardo. If it fails, I will send an email to support.
Cheers !

The Pro Trinket does not show up as a com port. Please read through the tutorial on setting up the IDE and programming the Pro Trinket

OK, so I read the tutorial, thanks again :)
I tried with my FTDI cable (which works with my beaglebone black) but no luck.
When I push the reset button, the red LED does not pulse and Arduino IDE (configured as mentioned in the tut) is giving me the "cannot find usbtiny device" error. Tried with avrdude and got the same.
I guess I'm done trying, I still have my Metros to play with but I wonder if I did not kill the board as I only have the pwr LED on and nothing else (even after pushing reset).
Thanks for your help !
Moving on...

Could be that the bootloader got corrupted. The bootloader is what pulses the red LED on reset. You can try to repair the bootloader:

Thanks for the tip, I'll do that as soon as I have a UNO.
I only have a Leonardo available right now.
Thanks again !

Hi again,
So I tried to re-program my trinket pro with my UNO but no luck so far.
I checked countless times the wiring, I keep having:
Reading signature:0
(no target attached?)
Signature fail

Couple of times I managed to have 'Reading signature:200'
Search the forum, replaced signature 950F with 200 in the code, managed to have a signature match after countless retries
but got this error: 'Failed to verify fuses'.

I must admit I really want to throw that thing away :)
I spent so much time trying to make it work.
Now I guess I'm out of options...

Let's back up. If you're using an FTDI friend, then you select the Pro Trinket (FTDI) in the boards list, and set the serial port to the FTDI friend. The FTDI friend will show up in the ports list.

Possibly, you have a bad connection between the FTDI Friend and the Pro Trinket. Can you post clear, detailed pictures of your soldering on the Friend and on the Pro Trinket?

Hi, thank you for your time.
I do not have an FTDI friend, I only have an FTDI cable. As with the soldering, I only have the headers soldered.
What I did was testing the board after I received my metro, metro mini and trinket.

So my FTDI cable (which works with my beaglebone black) shows as /dev/cu.usbserial on my Mac.
I tried uploading a simple program (blink) using Pro Trinket 5V board.
The programmer is set to USBTinyISP. I pushed the button to enter bootloader mode, clicked Upload and each time
It fails after 10 retries because of the programmer not being found.

I think I'm done trying, I must be doing something wrong but all my other controllers are working so I guess I will keep working with my teensy (I initially intended to port my teensy project to the trinket).
Thanks again.
