Product Information

I'll post clearer pics if anyone has problems. Ch341 can be left exactly as it was delivered. No soldering or additions are required. Leave the yellow jumper exactly on the two pins [as it arrived] on the CH341. CH341 is a USB bus convert chip, providing UART, printer port, parallel and synchronous serial with 2-wire or 4-wire through USB bus Flashrom is the software that you will use, for dumping, erasing and rewriting the contents of your NOR flash.

If you’re worried about flashing your motherboard with an SPI Programmer, then this is the guide for you. Each step is explained in detail, with pictures. We’ll go over everything, from buying your Programmer to flashing your chip with Flashrom. While blasting the chip with hot air, hold the chip with tweezers but do not use any real force. Do not try to forcefully pry off the chip. Simply hold the chip with your tweezers, gently nudging it until it feels like the chip can move freely. While in this state, the solder is fully melted and the chip can be lifted off with ease. But, if it does have the flip up cover and removable BIOS chip in there, it may program easier in a spring adapter directly in the programmer vs programming on-board with SOIC cableNOTE: debian, arch or void can be written instead of ubuntu2004. the debian script is also applicable to newer ubuntu versions ./update trees -b flashrom 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. That, or something else on the board is friend./shorted and the BIOS is not the issue. What happens exactly when you try to start the board? I am on limited internet, so can’t watch the video right now.

FlexWireTM technology, enables flexible 2-line to 5-line synchronous serial ports through software. press the Detect button of the software to recognize the Bios. The program should recognize the type, the brand and the model of the chip. if the Bios is still not recognized with Detect, then reverse the jumper in the mini SPI programmer and reverse the clamp on the motherboard’s Bios. There is no risk of short circuit normally.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. lift the arm of the programmer, insert the result in the mini programmer. The Bios should be on the left of the programmer if we look at it with the USB connection at the top). Enable the arm. La soluzione e' quella di sollevare il pin di alimentazione del CH341A (pin 28) e saldare un filo da questo pin al condensatore C4 (sul lato collegato al pin 9 del CH341A) e poi da qui, all'output del regolatore da 3.3v (pin 2). Quindi il cavo fara' questo percorso: Pin28 CH341 -> Pin9 CH341A (C4) -> Pin2 LM1117 (Regolatore 3.3v). Volendo, invece di sollevare il pin del chip, e' possibile tagliare la pista di alimentazione sulla PCB e saldare un filo dal pin 28 all'output del regolatore da 3.3v.

NOR flashes on libreboot systems run on 3.3V DC or 1.8V DC, and this includes data lines. CH341A has 5V logic levels on data lines, which will damage your SPI flash and also the southbridge that it’s connected to, plus anything else that it’s connected to. Ensure that all the joints are perfect. A good solder joint is shiny, and with concave fillets where the solder has flowed. Observe: Since the Windows tool has severe issues with some chips and doesn’t have an auto-verification system, your best bet is to do the flash from a Linux computer. If you don’t have one, you can use the instructions in the following paragraphs to set up a Live USB with Linux (a Live USB is one which contains an OS you can boot from and use as a normal computer). If you do have a Linux system already, you can skip to the next part of the guide. Then, press the Verify button to verify that the BIOS has been correctly programmed, that there are no errors. The software should indicate: that the memory buffer and the chip have the same code. The MEM mode provides signals such as A0, RD# and WR# etc. Which is similar to the memory read/write mode.

Conclusion

If the board you are writing to has two chips you’ll need to split the rom into two sections. For example, to split a rom for the x230, t430, t530, or t440p run: dd if=libreboot_12mb.rom bs=1M of=bottom.rom count=8
