arLCD HS 230400 Baud w/isp

[clementballot38]

Hi,

I recently updated my arLCD to the latest firmware (2p12) from the master branch of this repo. I updated both the firmware and the files.

Since then, I have the following message :

I cannot upload anything from the Arduino IDE, I get the following error during upload :

         Double check connections and try again, or use -F to override
         this check.

avrdude done.  Thank you.

Do I have to try an older firwmare ? Do I have to do something ?

Thanks in advance for your answer.

@clementballot38 I'm looking into this now. To be clear, when you say you updated to what is on master I'm assuming that you specifically are using commit 9c68b271652d94479026852a7da59b7a1ed6f20d which is the most recent commit at this time.

@clementballot38 I have successfully bricked my arLCD as well, I'm working on a solution to your issue.

This has happened to me too. I've pulled an old arLCD out of my drawer for a new project. This is a new Windows installation since last time (Win11 now). I installed the latest ArduinoIDE, added the arLCD libraries, then plugged it in. It was not recognised as a USB drive, but did recognise the COM port. I loaded the arLCDTest example sketch and then uploaded. Now I'm stuck on the same screen that @clementballot38 posted. This was without updating any firmware.
