Re: Disable USB for application protection

Hi, I have this same question. How to prevent access to the intellectual property on the device when the customer will have physical access to the device.
I am concerned about both RpiBoot access through the micro-usb, and also whether it is possible to simply boot into a different operating system ...

Re: RevPi ConnectSE unresponsive -- what to test next?

Hi Dirk, I finally managed to do a controlled trial of rpiboot. With a brand new Rev Pi, I was able to connect with rpiboot straight away. Then, immediately using the same host, same rpiboot software, same usb cable and same procedure, I tried to connect to the unresponsive pi, but it could not ...

Re: RevPi ConnectSE unresponsive -- what to test next?

Hi Dirk, thanks for your advice.
I may be misunderstanding something, but don't I need to be able to mount the Rev Pi drive using RPi Boot to complete the steps in the checklist? The Rev Pi will not connect with RPi Boot.

RevPi ConnectSE unresponsive -- what to test next?

Hi, we have a RevPi ConnectSE, maybe 2ish years old. It has been sitting unused for the last few months, but was working OK before that.

When power is applied, the PWR, REL and WD LEDs light up solid green, however: the Rev Pi does not boot up, there are no link lights on the network ports when ...

Re: Configure output relay behaviour on Connect SE

Thanks Giuseppe.
For future readers, my interpretation of this is:
* The Connect SE follows the rules for the Connect (not the Connect 4)
* When power is off to the Pi, it is as if the relay is open
* As soon as power is applied, the relay becomes closed, and there is no way to change this
* The ...

Configure output relay behaviour on Connect SE

Hi,
I am working on a project using a Revolution Pi Connect SE that uses the single output relay to control something.
We want this to be "safe", meaning if power is off to the Pi, or the Pi is on but our software is not running, or our software is running but isn't trying to control the relay, then ...

Re: On the rev pi web login page, the checkbox to disable reset password seems to be invisible

I have just done "sudo apt upgrade" and this has updated the web page to 2.1.0, and the problem is resolved.

On the rev pi web login page, the checkbox to disable reset password seems to be invisible

Hi,
I have notes from previously setting up a Revolution Pi that suggest that when you change the password for the web admin user, there should be a checkbox to disable the "Reset Password to Default" option. Now I can not find this option. The web page version string says 2.0.5 from 2020.

I have ...

How to read the single digital input on Rev Pi Connect SE

Hi,
We are using Rev Pi Connect SE, which has one built-in digital input and one built-in digital output. I can see how to read and write the digital output using the RevPiLED byte, but I can't find the documentation for the single digital input.
Is it perhaps in one of the two undocumented bits in ...
