When i try sandisk sdcard it can boot to hekate

But when i try this lexar on my hwfly it can boot normal
Is thia lexar not compatible with picofly ?

Lexar is a good card but chances of finding an original one are 10:1 or maybe lower
The amount of fake Lexar SDs on the market is unbelievable.

Hello,

I have a very bad day. I've dropped the screw driver on the SD/Gamecard board of my Switch oled and one of the capacitor (or so) has come off the board. Luckily, both SD and gamecard still working good. If you have experience if the capacitor will affect anything please let me know.

Thank you.

measured 3.0uF from the cap you missing. I guess you could use a 3.3uF 0402_6.3v

Anyone know where i could find those green dat0 adapters that you have to reball the nand to install? Cant find them anywhere online anymore.

hello. from the picture you posted it looks like all the fake ones. if that is the one you got, then most likely it is fake. if you are sure it's legit, there are some software utilities that can test the full capacity of the card. how much did it cost? the price is a good indicator as well.

If I let it be peeled off and continue using the switch, does it affect anything else? I'm waiting for the new board.

Thank you for your information.

It should work with both.
Maybe try formatting the card once more with the sd formatter :

Maybe the Picofly is more picky about the details.

H2Testw is a good start when in doubt.
There was someone on Reddit who complaint about a legit Sandisk card not working regardless whatever he tried.
So there might be something that needs to be right for the picofly to work.

I prefer 2.76.
2.75 already fixed the 'shutdown' issue though.

This is what i understand about the changelog of 2.76:
* Finer timing step for searching glitch point from 10 -> 8.
* Change algorithm of waiting for glitched identification on dat0.
* Change of the timing parameter when uploading data to the emmc via dat0.
(Its pretty drastic from 4248 to 527. I've no idea what is the impact. But i think it is modified by trial and error.)

is there 2.76? i only found 2.75 on rehius repo

Theres update on the github, but no compiled release.
You need to compile it yourself.

I've compile it myself and share the 2.76 firmware in previous post.

Hi. I found In AliExpress a lot of Instinct clones with RP2040 chip. They are about 10€, and I suppose the installation in OLED is toooo much easy and clean with flex cables. Anybody try them? Assume they use picofly firmware.
Thanks!

i tried this (in the photo i attached) and it's working well, i just preferer this because flex cables don't get twisted when installed

The price is good
Im using it for my hwfly and sxcore and its working well
But when i try with picofly it say failed to init sdcard

This is video proof about the sdcard im testing to different switch with different chips

You don't use the 3.3V from the sdcard reader right?

Im using this 3.3v

Thats already correct.

It doesn't make a sense for microsd reader to be interferenced by the picofly.
Since picofly doesn't take any line on it. Some people use the 3.3V from the reader, and thats the cause of the problem. I am pretty sure the problem is lay on other factors.

When you said using sxcore is okay, picofly not.
Does it means, you are not changing anything except the board only, then failed? Or you change some then failed?
