USB Host crash bug

[fangxiang-gan]

I am using the gp2040-ce_0.7.10_picofatingboard.uf2 firmware, and I have repeatedly verified this bug. Specifically, when setting up the USB Host, if Pin Order is D+/D -, it can be saved normally. If Pin Order is D -/D+, the chip will crash and cannot be saved. Please fix it, thank you.

Hi @fangxiang-gan ,

Can you please elaborate on the chip will crash and cannot be saved.

Are you saying that the change cannot be made on Web-config or are you saying that the whole device becomes unresponsive after attempting the change?

Also can you please list any other changes you have made to the setup of the device before I attempt replicating.

Yes, if configured like in picture two, the entire chip will freeze and not respond. It is necessary to unplug and power off again. Re enter the webpage configuration backend to check, the previous changes are invalid.
After flashing the firmware with a brand new one, except for the item in picture 2, the problem can be reproduced without any other changes, 100%.

Additional note: As I need to use pins 18 and 19, I have set the Player LED Type to the off state. As shown in the picture

Do you have another device to test this on? I would have to check but I believe that the PFB has resistors on those GPIO unless you are using a clone or version of it without them.

My newly purchased Pico will arrive tomorrow, and I will test it again and provide you with specific feedback on its performance. Thank you for your reply.

Confirmed issue, as long as it is set as follows, it will fail to save and fake death.

The brand new genuine chips I use are PICO and PICO H.
