FPC connector and LED look different from rev1.1 I have
Apparently this is the new batch... not 100% sure. Just got them this week and ordered a week ago.
Have ordered all my rp2040 chips from this seller: https://www.aliexpress.com/item/100...sea!CA!4445587266!&curPageLogUid=AdugGAB9hBR6
But some new developments from my testing. It seems something has changed maybe with the led and appears to have flashed properly but the led is not lighting up.
I was able to flash fw 2.67 and got a green led once it finished flashing. Installed the Tiny and confirmed with picofly toolbox that it has 2.67. Used the update feature to flash 2.73 which was successful.
Now here's where it gets interesting as the next reboot, the led stayed blue even though it glitched successfully and booted Hekate. Rebooted again and the led doesn't light up but glitched fine. So something is up with the new led maybe?
Might swap the led from the zero and see what happens

Yes. I had ones with those connectors last time I ordered maybe one month ago.

Do you buy from here
https://www.waveshare.com/rp2040-tiny.htm
Or from other shop which claimed original?

that's clone for sure, official WS has the big WS logo on each pcb(adapter & rp2040)Apparently this is the new batch... not 100% sure. Just got them this week and ordered a week ago.

Aw dang, you're right! My adapter bought previously from the same seller has the WS logo. Won't be buying from them anymore!

I bought from that seller too, but thankfully its the correct one.
It seems you got the new batch, the price is increase 7%.
The picture also update, its not the usual connector.
Its weird usually when the price increase means it have a better quality.

I think i understand, they change the fpc connector.
The previous batch have a buggy connector.
But that new one seems have more height then the previous one.
Did they now that Height matter on this mod
Post automatically merged:
This in my order history.
Still the old connector.

Why buy from aliexpress? Isn't it cheaper to order from waveshare directly? For me it's cheaper or at leasr the same price, with the additional benefit of them being the original products.I bought from that seller too, but thankfully its the correct one.

For me its still cheaper from aliexpress than waveshare.

Since i know little bit about electronics. I don't mind buying fake product, as long the price is reasonable for the product. I could calculate myself, how much the production cost, time, and effort to produce it.
Oh I didn't know you could purchase from waveshare directly. Will look into it. Thanks

No, bought from Ali which turned out to be a clone. It works fine but curious why the led doesn't light up with fw 2.73 and need to do more investigation. Led lights up with fw 2.67 so it's odd. I checked the led vs a zero and they look the same. The zeros I have flash normally with 2.73.

check R5 resistor value if it's 10k ohm

I guess you measured in circuit, but I bet you issue might not be resistor but maybe the led itself.
RP2040 zero has no resistor on LED GPIO16 line. tiny has 10k ohm both datasheet and R5 resistor I measured.
Thanks for the help!
I swapped the led with a zero but made no difference. If I had one of the previous Tiny boards which worked fine (from the same seller) I could investigate more.
Oh well, guess I will stick with fw 2.67 on these boards as I would rather have led codes rather than none
I've made a research this weekend on the firmware.
I've googling rp2040, and it seems it couldn't shutdown itself properly.
https://forums.raspberrypi.com/viewtopic.php?t=340301
The best solution is to make a physical/electronical mechanism to take the 3.3v out from the board.
I've tried to disable vreg regulator programatically turns out it make the gpio impedance into 14ohms, which ofcourse interfering the cmd's emmc line. So back with using the lowest vreg, to minimize draining power, and it gives the good high impedance.
Turns out, the problem with slow emmc, some of it could be from the firmware.
I recently got a v1 device which got slow emmc even with 100ohms on dat0/cmd.
@rehius
This line of code, seems never executed
https://github.com/rehius/usk/blob/1a39e9b46dac3ab7ddddad647d03575e41655dbb/misc.c#L38
I don't know exactly what happened. It seems the rp2040 still running.
I kind of fixed that part, and the slow emmc problem disappeared.
If you want too, i could PR it. But its an ugly patch. Theres dependency on pico-extras.

Hello all, I’ve installed rp2040 to many nintendo.
And I found many issued afrer 1 month.
-switch restart itself after attach right joy-con
-rp2040 cannot glitch if the micro sd is inserted.
-found shorted at 3.3v
-failed to init emmc(oled model)
-rst is not connected but it worked before.
-faile to init sd card
I don’t know what happened.
So anybody found the issued same as me?
Or can anyone suggest what it went wrong or what I done wrong.
I use
-rp2040
-awg30,36 wire
-47r, 1000 resistor
-dat0 adaptor(oled model)
-flex cable from v2.
-2.73 firmware (2.63, 2.74)
Please help.
Ps. I will insert pictures tomorrow.

- You should use 38-40awg, no need to use thicker wire.
- 47ohm and 100ohm, no 1000ohm (maybe it was a typo).
- Most of the dat0 are shit, so if you are not sure you got the right one this can be the main issue for most of the things.
- Flex is hit and miss at this point, you are better using bare mosfet.
Add to this flux residue, cold joints, posible shorts after shield placement, possible wrong sourcing of 3v3 and gnd (especially on Lite) and you got yourself the recepie for 99% of the issues you described.
Lets see after you upload pictures...
