"no contact with CH341A" with windows or chip ?
check usb cable or chip connection

when plugin with windows it should instant reconise the device

For everyone interesting, there are many other software for CH341A.
My favorite is Neoprogrammer, search in google for it.
It support much more chip than stock software.

is it possible to flash a 1.8v chip with a 3.3v programmer (ch341a) if I disconnect the VCC ? so I use the power of the board.
( i have a clip )

Do u have a green or black programmer? Green is 3.3V but black is 5V. So I think u can take a risk with green one but not black one. It also depends on the chip if it can tolerate high voltages or not. Better use a 1.8 adapter to be safe than sorry later.

For 1.8V you need a voltage adaptor, that fits into the CH341A.
I have the black version with this 1.8V adaptor (from Aliexpress).

By his pdf it states: "Single Power Supply Operation
- 1.65 to 2.0 volt for read, erase, and program
operations"

So u must try it with no adicional pw as it may damage.
Any other issue is related to circuit motherboard to the spi.
I would de-solder the chip and programming it in a soldered pcb.

There there three
The newest BIOS's from B550 MSI have Level 3 write protection.

When I try to disable it, then read it, it shows FF, how do I disable the write protection?

Asprogrammer says I'm connected and flashed the chip without saying write protection might be enabled when I write all three registers to 0, then hit the write remove icon.

But after I flash when I read the chip it shows all FFs. :(

Am I doing this right, this version of Asprogrammer has an option for my chip and takes about six minutes to flash it.

Never mind, there is a broken wire on the SOIC clip. :(

Hello,
I want to make a backup of my bios. Is this chip the right one? MB Asus z690-a strix d4… Mxic 25v5126f…

Nah...it should be under the bottom heatsink, my guess this one, as still there isnt not much info around...as u probably already know also.
And if so...the regular clip (SOIC8) wont work as this seems to be WSON8 surface soldered.
My opinion only.

Yes, you are right. Thanks! :-)

Hi, the DELL 980 motherboard was flashed to boot without any screen.
I have backed up the fptw64 -d Bak_DELL980bios.bin file with the command

How can I use the programmer to flash this Bak_DELL980bios.bin file? Should I burn in one chip or two chips?

Hmm... what do you think about ch341a with built-in voltage control?
Unfourtunately I cannot insert links yet
Considering buy one piece for testing on Ali.

Hi there,

first of all, my English is unfortunately not very good

I still hope that you can help me.

I have an Asrock Fatal1ty X470 Gaming K4 that unfortunately died after a BIOS update to 4.40.

I have now bought a CH341 with a 1.8V adapter and want to re-flash the BIOS

my chip is a MX25u25645GMI00

Is it possible to flash the whole thing with Windows? If necessary, I have a Raspberry Pi on hand

can you write me a little guide for noobs;)

CH341 Programmer does not have my chip

Neo Programmer doesn't have my chip

Thank you very much

CH341a v1.34 from SkyGz has it.
MX25u25645G: https://www.macronix.com/Lists/Datasheet...6Mb,%20v1.4.pdf

Further settings and guidance:
[Guide] Using CH341A-based programmer to flash SPI EEPROM
[GUIDE] The Beginners Guide to Using a CH341A SPI Programmer/Flasher (With Pictures!)

And theres nothing special for "noobs" and first timers... read and learn and dont expect a one round success.

Make valid backups of old chip content even if you think it's bricked anyway. This way you'll learn the handling of program and programmer and if needed and possible board s/n, mac ... might be recovered from that dump

I'm trying to flash a board with a Winbond 25Q128FWSQ, I have a CH341A flasher with a Pomona 5250 clip. I have a 1.8v adapter, which I've measured with a multimeter to make sure it's 1.8v

I've tried various softwares, they either read nothing or don't detect the chip. I've tried clipping the clip on multiple times and still got nothing. Anyone know what is wrong?
