Hey guys,
I designed an RP2040 pcb that has been remade a second time. The first time was a crystal issue, but had a very messy decoupling capacitor layout, hence the remake. This time, the board simply gives code 43 on windows, rendering it unusable. After giving a closer look at the pcb layout in KiCad, it looks like in making the pcb I linked all my 3V3 pins on the RP2040 chip together, as it looks like they all lead to the same 3V3 plane in the RP2040 example. I also read that there could be a ground issue if the ground pad in the middle of the chip isn’t connected properly. If anybody has any possible solutions to give I’d highly appreciate it. I can also post images from KiCad if needed. Thanks!
