Hi all,
I've just put together a custom RP2040 board that I'm designing for a drone. However, flashing the program doesn't seem to be working. It always starts in BOOTSEL mode, even if the button is not pressed. I'm using the W25Q32JVSSIQ flash chip. I looked at some other forums that said to use picotool to check if the flash is working, and this is what I got:
So it looks like the flash is not writing anything at all. Here's a schematic and board layout. If anyone sees any problems, please let me know. Everything looks ok to me, so I'm worried it may just be a mistake in soldering. If it is, I'll probably just have JLCPCB assemble it for me since I'm not good with placing the tiny parts lol.
I would appreciate any advice you guys have, thanks.
