In my Pro/Max board, I wanted to connect a mini USB printer. To do this, I enabled USB Printer support under Device Drivers → USB support → USB Printer support in the kernel configuration, and enabled USB in HOST mode through the DTS.

My board is powered by an external 5 V supply through the VSYS ...

They could have used RJ-45 with LEDs

I want to disable the use of ADB or USB virtual network interface since I don’t need it. I read in the Wiki that switching the USB to Host mode disables it — is there another way to do this?

Thanks in advance !

Hello, I don't know how to upload this. This isn't a problem, but rather a project using a Pico Max/Pro with an application in Go.

Hello, I have an application that is compiled outside of the framework. It has been successfully tested on my LuckFox Pico Max board. I need to place this application (executable) somewhere within the SDK so that the next time I perform a full rebuild, it persists and I don’t have to copy it ...

Thanks !

What is the maximum current that the 3V3OUT pin can supply? I have a Pico Pro/Max.

Thanks in advance !

2. Before the kernel loading stage, the USB is always in peripheral mode, and flashing is also done before the kernel loading stage, so it is still possible to use USB for image flashing. Although using UART for flashing is feasible, it is time-consuming during downloading due to the maximum baud ...

Hi, just to confirm.

• Power is supplied by the VBUS and GND pins (5V)

• In this mode, the SocToolKit via USB is not allowed, I suppose it should be done via serial port

Thanks in advance
