Re: CH341a SPI / I²C programmer

Have you used this? Says it has a virus

if it's originally from me, then it's direct from the site of the author.
anything over v18 is risky because they are in virtual containers that emulate a registered machine.

Re: CH341a SPI / I²C programmer

What happened?

Also I'm new to this eeprom thing, for future reference how would you know what size memory and whether it uses SPI or I2C when shopping for blank ones? Or is there one common type used in TVs that differs from a PC?

25 series is SPI, 24 series is i²c
the letter(s) after the number can be ignored for now,
the next set of numbers relates to the size.

The size is denoted in the markings on the flash/eeprom. Winbond W25Q32FVSIG

This should be version 1.18

Re: CH341a SPI / I²C programmer

given the bs i went through last week, they probably got stolen from a production line for DELL motherboards!

Re: CH341a SPI / I²C programmer

Ah actually it finally detected one. After trying 4 from a strip of 10. So they must just be a junk batch

Re: CH341a SPI / I²C programmer

try flashrom

btw, are you sure they are connected right?
any 25 series should be detectable, even if it's not supported.

Flashrom a program?

And they’re connected right it doesn’t detect just shows all values as 0

And if I try to program it will sometimes complete but when verifying says “chip with the contents are in disagreement”

Btw how do you know if it’s a 24 or 25 series? I’m not too familiar with eeproms

Re: CH341a SPI / I²C programmer

Is there a way to add them to the list somehow or I need to get a different brand?

Re: CH341a SPI / I²C programmer

Ok so my problem is the eeprom chips I bought aren’t detectable. They’re a Winbond W25Q32FVSIG

Great thanks. What I’m confused about is when using an eeprom from a tv, it doesn’t give a detect option unless I use the 25 SPI BIOS slot, but this wouldn’t be for an eeprom correct?

Re: CH341a SPI / I²C programmer

I just got one of these CH341A Programmers for TV eeproms.

Version I found is 1.13. Where can I get 1.18? Reading that it works well for people

Also does it have an auto detect feature? If not how do I figure out what type of eeprom it is to select in the program?

This should be version 1.18

Re: CH341a SPI / I²C programmer

The developer of the software is pretty nice. It was 10$ USD for me for the latest version, v1.31, with free upgrades he says. I had trouble tracking him down, even though his e-mail address is in the program. I didn't realize it was an e-mail address because the font was a little funky. It's SkyGz@QQ.com

Just tell him you're looking to purchase a copy of the CH341A Programmer. He'll ask some questions, send you an e-mail with the new version, have you tell him the Hardware ID, and then send you a registration code. For 10$, you can't really go wrong.

Although his website is in Simplified Chinese, he understands English very well.

Just thought you guys would like to know.

Re: CH341a SPI / I²C programmer

If you need the registered version I can put you in contact with the author. He will probably sell you a license for $5 or so.
