Hacking Hardware Picofly - a HWFLY switch modchip

When updating v2 Mariko Samsung eMMC from 2.70 to 2.72, the error message "== CLK is not connected" occurs, and I am unable to update the firmware. It remains at version 2.70.

woops, I completely missed the reply. In regards of the sarcasm stuff I'm not used to the notifications of GBATemp and I missinterpreted that comment as a reply to my direct comment, my bad I'm still learning my "foruming".

As for the lenght, I agree. I can try to make them a little more flush on the board. I'll definitely take that advice

As for shorts, I usually run continuity mode to the next-most points to confirm if they're shorting or not, but I couldn't pinpoint anything at the moment I performed the check... maybe it happend after I closed it if at all?

In regards to the mosfet I think that's due to the angle I took the photo. They're actually not touching, let me post another picture rq.View attachment 372279

I was most concerned with the emmc connector or the motherboard socket for said connector.

Is 0.1mm wire good for SDA/SCL or should I do it thicker?

Already compiled it, and success generated the uf2, but still not yet test it on real device.
I don't know the purposes of busk, only compile usk.

usk is "no_flash", so you have to use prepare.py to make a complete .uf2
until that the firmware is RAM only

What version of the fw are you using on Pico. It looks like 2.72 might have an issue with samsung emmc on Oled

My pico FW is 2.72. How can I fix it?

I try to copy pins.h from usk, and the compilation succeed. Is it the same file?

yes

This is the uf2 that we usually copy, isn'it?

yes, + update.bin

I read in the readme in busk. Do we need to modify the memmap_default.ld in the pico_sdk according to that address?

I think it would work without such modifications. I do that just in case since in a boot process the main firmware overwrites interrupt vector table

I successfully updated to version 2.72 using the new update.bin　Thank you!

What changed in v2.72? Also is the color code different? I had a strange behavior whee the glitching starts until after the console started booting and this never happened on v2.67

What is the problem with my Switch OLED? I measured diode value and it shown as below :
RST= 1.239v
CLK= 0.763v
CMD= 0.530v
DAT0= 0.760v
SDA= 0.912v
SCL= 0.903v
anyone know the solution, pls kindly share. thank
