Youmile USB Programmer Series Burner Chip 24 EEPROM BIOS Writer 25 SPI Flash + Sop8 Test Clip

Product Information

If flash chip is detected you may try reading (dumping) the flash contents now, or you can try flashing it with a new ROM. Similarly, the SPI flash chip has a minimum voltage it will accept as a high logic value. This is commonly 0.7*VCC for SPI flash, which is 2.31V for 3.3V chips. If the drive strength is too low, the voltage at the pins of the flash chip may fall below this minimum voltage, causing it to register as a low logic value instead of the high value that was sent. If you are trying to flash your board with an SPI, there's a good chance you already know the basics of Linux. Even if you don't, though, I'll still go over it.

Note that the device works as a programmer only if ACT# pin is connected to ground via a resistor. That's why you should put a jumper across pins 1 and 2 of the UART connector. Otherwise the device will be recognized as a standard USB to serial converter. Drivers and toolsWhat do you recommend to progress on the CH341A SPI Programmer/Flasher procedure compatible with this recent ASUS Prime Z390M-Plus motherboard ?

Use of flux is very important, to get a good solder joint, because it removes oxides and prevents further oxidation during soldering, ensuring that the solder flows properly, otherwise the solder will ball up and you won’t get a good joint. Notice that the kapton+foil does not cover the chip itself, or the solder pads. It’s important that these are exposed to the heat. If you use a SOP/DIP adapter with a SOIC8 IC, you’ll have to solder it obviously. K tip is a nice choice for soldering ICs like these. Use good flux and 60/40 leaded solder (or 63/37), none of that Rohs lead-free crap. The chip is still readable and writable, so I guess is not totally fried (if so, peace, I'm just experimenting in a world I don't know at all, as said I fount this laptop in the trash).

Recommendations

You can connect a SOIC8 test clip, but you will struggle to get good connections and it will be extremely unreliable. DO NOT solder to the pads of the WSON8 directly; some people do this, but you shouldn’t do it, because you can easily damage the pads that way.
