Which microscope do you use??
I paid 65€ for this crap.It's an Andonstar AD207S. I can highly recommend it. https://www.aliexpress.com/item/1005006288677413.html
I had the same issue twice, first time because the pico was wrapped with kapton tape and the second time because the wires were too long, I solved the second issue with sda and scl pointsHello All, My switch lite is not starting hekate. The picofly show an error "**= No eMMC block 1 read (should not happen)" And i am not able to find information about what is happening.
Why kapton was causing problems? I dont have long wires at all but some kapton on some solders to keep them in place betterI had the same issue twice, first time because the pico was wrapped with kapton tape and the second time because the wires were too long, I solved the second issue with sda and scl points
hello friend. can you give me the dimension of aon6414a. if it too big i can use it as rear mosfet. i have a bad batch of irh8642 now so i wanna try something else for stable installation.Its happen to me today
Ordered 10pcs mosfet irh8342 from my local shop
And none of it working
I ussually use aon6414a and its working fine
I just concern about the size, thats why i try my luck use irh8342
I try single mosfet and double mosfet and its not working
When i try to switch to aon6414a its working fine
Im really sure this mosfet is defect or something
Forgot to mention. Testest with hwfly: same behavior.So you mean its happened on all variant, when rebuild nand?
Does anyone know how to retrain the rp2040? Thank in advance.
Nicely done and very neat. Where did you get the coloured wires? I'd like to do the same chip placement but thinking I need those wires to tell each apart to make things easier lol.2 switch down.
Probably bad glue, which conducts a lil bit, tbh I have no idea. I know that I buy cheap stuffs from Ali, so it's better not to trust any sellerWhy kapton was causing problems? I dont have long wires at all but some kapton on some solders to keep them in place better
Today i have done an oled with reballing emmc. Everything works fine but the training was a little bit slow so i want to retrain it to see if it gets better.Start the Picofly Toolbox. You can reset it there. But why do you want to do that?!
Check your right joycon cable friend. Sometime we neglect something.After i installed picofly on Switch Oled, right joy-con won't charge and detect any more and it works only wireless. What can be wrong ???
joycon cable is ok, i think it' something on board.Today i have done an oled with reballing emmc. Everything works fine but the training was a little bit slow so i want to retrain it to see if it gets better.
Edit : still the same. I don't know why but this is the first time i get a samsung emmc training at 10-15s. Usually they done the training at 1-2s for samsung variant. Check all points and all good. Don't know what to do.

Thanks lol. I do not have the hand eye coordination or tools for something quite that clean, unfortunately. I'll isolate the wires and try again.Is it a guinea worm? is it a spider's nest? is it cordyceps? I'm traumatized
...to be a bit more constructive, you've stripped the insulation off of your wires in several places, and whenever you close the shield it will connect with the uninsulated wire parts and short your mosfet wires to ground.
I'm attaching a pic of one of my installs, for reference
Thanks, i test this today and it work.... thanks a lot !!!To desolder them is easy. Just cover them in a blob of low melt solder. Just make sure not to bridge any of the nearby pin of rp2040.
After just add 47ohm on the pin header 27 28 29. Dont forget to bridge the resistor pads though otherwise you wont have continuity.
Thanks to u again, i have a debug led on the chip !!!It will be this if its following the same schematic as the waveshare one. Just measure. The line is going through gpio16
I paid 65€ for this crap.
I've bought part per part, and assemble myself.Not exactly crap. I also started something like that once. It was enough for many projects, but then I wanted something better.
I also got one from Andonstar, similar to the one from @deeps
I was very happy with it, but the small work area was too small. So I sold it again and in the end I'm more than happy with this.
