Dat 0 adapter and flex cable v2 cpu. 47R smd resistor. Rp2040 chip. And digram hwfly chip oled on youtube bro.

just built the adapter since i didnt have the otherside of the connector so i pealed of a bit and solderd it to it and addes some uv resin for streng and well guess what im able to flash it :-)

edit: i realized the picture is uploaded showed outter bridges so i added it so no one bridges THEM xD

This oled diagram should be correct I think. Can anyone confirm?

Oh I heard via my sources this is the only chip that the Toshiba memories works great on. Even HWFly got some issues with them.

Hello,can you please tell me what type of clear glue do you use ? Thanks.

Is there any way to change the pins used? I have a couple Tiny2040, they have all the pins needed minus pin 15

Yes u will have to install a second MOSFET like @rehius said I had the same issue after installing second MOSFET it worked fine

would you share a diagram for 2 mosfet intallation?

you need this pin...dont seem to have SPI1 TX anywhere on this tiny2040 but you can give a shot to pin 3 or 7 on you tiny2040 maybe it will work because its also I2C1 SCL its my guess....

Thank you very much!

I'm using RP2040 one and I'm only getting one quick red light. Is it my installation or the chip is blank (i hold down boot, plug it in and drop the 2.5 fw.ufc & reboot)? I'm using the v2 hwfly cpu cable on a v2 (use the 3, 4 or 3-4 points on the cable), added 47 ohm on the 3 points and 20 ohm on the reset point. I tried my wiring (removed the wire on the cpu cable and removed the resistors) with hwfly oled chip and it boot up.

Try to remove the 20 ohm resistor on the reset..try without anything. If its not working you can try with 20k ohm or 30k ohm on rst point.

CYAN - no reaction to glitch. try installing second mosfet like on the picture few pages ago

thanks @rehius and @Dee87!

I installed a second mosfet as per instruction, but it keep booting to OFW and a red screen.

I'll order a lite ribbon cable and try again when it arrives. It seems I can't install mosfets adequately.

Nah, im pretty sure it has to be enabled on a software level. Them being I2C1 just means they can't both be configured to it at the same time with different signals. Might not be too hard to modify on an asm level..

UV Resin is what i used in that picture
