Keep working on it just remember this gbatemp golden rule...

Less promises and forecasts and more actual results.

Now you're gonna get a bunch of PMs askin you about your HaxChi fork lol

I know but i's not like i said "Hey come play all the switch games on Wii U..." (It's a bit like Clickbait, you know...)
And in fact on my thread i had like 80 peoples watching..., Here we have 15 so...

That's your issue. You're thread had 80 people watching because you posted a hypothetical. Wait until you have something real to show

I agree with Kafluke. Keep doing your thing, but don't announce anything until you have a proof of concept to show off. I learned this the hard way while working on Trinux as well. People will rip you to shreds unless you have some sort of proof, that's just the nature of how the scene works. Proof or it isn't possible. Sure some of the nay sayers are right some times (I had people like Marcan correcting me at times who really know their stuff), but if you truly believe you have a concept that "could" work get it working first in a really basic way (probably only useful to other devs initially) and show that off. Then you will earn other's respect and may even get some help trying to achieve your goals.

GBATemp can be a pretty toxic place when it comes to announcing homebrew etc, but rightfully so. Plenty of trolls have come and gone promising great things and delivering absolutely nothing and disappearing altogether. They do it for their 15 seconds of internet fame and take off. That's why there are so many skeptics on the Temp. Get something running (doesn't have to be pretty by any means) and then announce it and you should be fine

Hey, long time no see GBATemp !

I'm trying to read the Wii U Gamepad firmware in the 25Q256A chip to be able to fix it.
Here is my setup so far :

Setup : https://framapic.org/dPohf1hGTNja/lajhXgrdC3In.jpg

I'm using frser-duino using an Arduino Uno R3 along with flashrom (tried latest stable and master)

So far I'm only getting :

Code:

antoine@desktop-antoine:~/dev/flashrom$ ./flashrom -p serprog:dev=/dev/ttyACM0:115200 -r gamepad.rom
flashrom v0.9.9-109-ged098d6 on Linux 4.4.0-104-generic (x86_64)
flashrom is free software, get the source code at https://flashrom.org

Using clock_gettime for delay loops (clk_id: 1, resolution: 1ns).

Found ST flash chip "unknown ST SPI chip" (0 kB, SPI) on serprog.

This flash part has status NOT WORKING for operations: PROBE READ ERASE WRITE
The test status of this chip may have been updated in the latest development
version of flashrom. If you are running the latest development version,
please email a report to [email protected] if any of the above operations
work correctly for you with this flash chip. Please include the flashrom log
file for all operations you tested (see the man page for details), and mention
which mainboard or programmer you tested in the subject line.
Thanks for your help!
Read is not working on this chip. Aborting.

I have a working Wii U Gamepad in case, but I would be able first to read the « not working » Gamepad chip before opening/tearing down the « working » one.

Any help is appreciated, and by the way happy new year 2018 !

So, I managed to dump it ! Using latest master branch of flashrom and kept pluggind the gamepad to the AC power
