have you try format sd card using that " switch format menu? "
i mean from ofw boot


View attachment 406491

after you finish format

you can put that sauce file
try boot

Ok lemme try that

Already try that
And still the same issue

I think picofly somehow reject this sdcard to initiate boot

i see...
hope other can help


should try with another sd card then :V


getting new sd card might cost ehe

Lol
Thats for sure will solve the problem

Im just curious
Why pico fly cant work with this lexar card

yeah
idk what make the card not work


have you try with another sauce file ? (pack uhuk uhuk...)

Yes i try every pack that i can download on internet

if you have sd card problems on picofly and they work on hwfly, use hwfly's sdlosder on picofly

Im sory but its new for me
Can i explain more detail about it ?

https://github.com/hwfly-nx/firmware/releases/download/0.7.2/release_072.zip use sdloader.enc and install with picofly toolbox

I still got failed to init sd card

the sd card is now read, hekate starts

However I think the micro SD is fake, try it

I think it flash the picofly chip and change the bootloader
If u say this sdcard is fake
Then why it can boot normally on hwfly chip ?

It still not read the sd card
The bootloader on the pico chip is change
This happen when im trying to turn on the switch without sdcard

This is sdloader of hwfly

 

[nclabz86]

Yes but on pico chip
Still the result is remain same

Just try this. Do a low level format on sd card or just do the wipe option on any professional partition management program. Then proceed as you always do. If after the wipe, the sd card does not behave properly just discard it.
It has heappened to me before.

the funny thing about this sd card is
i try to put it in to my picofly in V2 and its boot to heakte normally and the SD Card is work
im like TF!!!!
not working on switch lite
but working on my V2
same chip
same file
same SD Card
lol im confuse XD

Like i said, its not about the picofly.
Picofly do not touch any line on the microsd. Its something else.

My guess is your nintendo switch lite are problematic.
It could be that the 3.3V line that goes to the usd reader are problematic.
Or the usd reader slots are problematic.
Or some power ic, or some power regulator problematic.
Theres too much possibility to list on.
Its not worth time to track it.

One thing for sure, less probability that picofly have anything to do with the usd reader.
Picofly doesn't touch anything about usd reader.
The picofly only working on the emmc and cpu.

Its like saying, why this airplane problematic, maybe because of the paint color.
Which is almost impossible paint color have anything todo to the airplane work mechanism.
Theres lot of other thing that more probable, such as the cpu, the sensor, the weather, etc.

and why with the same switch lite + picofly but different SD card lets say my sandisk its working fine ?
weird right ?
XD
so its not the switch i think

i had 1 case(customer device) like you but it caused by my faulty v5 hwfly. after the chip burned the emmc(while trainning it got very hot) i had to replace it with rp2040 clone and the samsung 128gb in this never got innit on that particular device again but it worked with other device. in the end i had to use another samsung sd card for it, i'm still not knowing why still this day.

Every microsd have an ic inside it. And every of them have different datasheet.
With a slightly change, lets say voltage which is outside of the tolerated one, and the ic might failed to work. Lets say its supposed to be 3.3V but it supplied with 2.5V, will it still working?

And how about the mechanical nature of the microsd. What if the lexars conductor are 1mm shift of, such that the contact is failed.

Theres too much scenario that might be the reason of.

For what i know on how picofly works, Picofly doesn't touch microsd at all. How could it be the probable cause? What picofly doing, is sniffing the emmc, then 'diminish' power supplied to the cpu at a certain time and interval, such a way that the flow of code that the cpu run is shifted avoid the boot security and run the code in the emmc at certain address. And this address is the place that sdloader are uploaded by the picofly to the emmc. And the sdloader will mount the microsd and run the code inside it. Then you have hekate, and the parties goes on.

What firm flashed on RP2040? As far as I know, you must see the raspberry icon when starting without SD card.
