With the Pico and Pico W both using 5pin Micro USB (I loathe Micro USB), and the annoyance factor of having to open up the entire system to access that port, I want to run an idea past the more knowledgeable people like
@hdx.
I was reading through the Pico’s documentation on the official site and I BELIEVE it said that you can remotely reboot the Pico into BootSec via the USB port, and you can also send a command to toggle the 3.3V pin. If this is true, would that safely allow flashing without the need for a diode or disconnecting the 3.3V pin before updating?
If it would make it safe, I am hoping that I can do the following: DIY a USB extension that runs from the Pico’s Micro B port out the SP2 bay’s notch (so no need to risk damaging the shell of the console) ending in a USB C port. Now, I am looking for that extension to meet the following specification:
- USB Micro B (male) to USB C (female) preserving the symmetrical usage for the USB C port.
- Provide both power and data to the Pico via the USB 2.0 spec.
- Support OTG concurrently with power so that I can do the flash from my phone instead of my desktop pc.
Please let me know your thoughts, advice, perspective, and insight.
