It is possible that your points CMD and DAT0 require an additional resistor of 47 Ohm.

Personally, I only use original RP2040 Zero or Tiny. Depending on the version, I either make a total of 100 ohm resistor or I extend the existing...
You can't say that in general. Maybe the switch took a little fall or you didn't apply the solder well enough.
Just check all the connections again. This will give you a starting point if necessary.
Check your soldering points. You may have cold solder joints or a connection may have come loose.
Without an SD card, at least some text should appear.
It is quite possible that the resistors there will have to be adjusted first.
Otherwise it may not start in the OFW/CFW.
And last but not least, I advise against these chips. It is better to use an original RP2040 Tiny or Zero and remove the...
If the screen remains black even without a chip, your Nand is corrupt. It's possible that your chip shot it. You would now essentially have to use a donor Nand to get access to the system again.
Great! I've ordered them as well. 100pcs (panelized 5x4) since I have plenty of rp2040 chip with me. 😁 Expecting them to come after 2days.
Thickness of the board I have set was 0.6mm (same as the prototype)
This was the initial version of the...
Always take it easy. This is a forum and not an active chat.
To me that sounds more like cold solder joints.
Can you please take some pictures of your installation.
