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

Product Information

All you need are the drivers and the AsProgrammer software which can be found in the following links. Two modes of programming and serial port are optional, and online switching does not need to plug and unplug USB. After downloading the software and installing it on my Windows laptop, it was time to pick a target. I dont have a previously saved good BIOS file, I backed up what was on the assumed corrupted bios chip using flashrom but when I read that in FD44 its blank. This guide will help you get set up with your CH341A programmer so you can start taking advantage of the tool’s many features.

The latter are signs of a 'dry' (bad) joint, too much solder and either movement while it cooled, not enough heat or a lack of flux, maybe due to carrying * the solder to the joint on the bit so the flux core burnt off before it got there - Always apply the solder to the work, never to the bit (except after wiping it, the bit needs a tiny drop put on it for good heat transfer). For the people that had the same problem(s) here is a photo of how it should be connected propperly. Su satisfacción es nuestra primera y principal preocupación, y es nuestro logro en nuestro sitio web.EDIT: The S/N found on the back of my board seems to be 3 characters short from what FD44 seems to be requiring.

I strongly recommend practicing adding mod-wires to scrap boards, and also removing and replacing components on them to improve your skills before you work on anything valuable. The Acer ‘exe’ can easily unpacked with 7-zip, but it contains 4 different bios regions (still no complete firmware image! It pains me to think how many people have modded and lost 5v compatibility, or botched modding these perfectly fine programmers. Esté siempre atento a las múltiples promociones de programador en AliExpress, para que pueda comprar programador a precios aún más bajos!that there is yet another fault in the design to reset / set the QE bit in the second status register. The original recovered CH341A will be used in project as daughter-board and/or its components transferred to a new design PCB with additional mods i. Although this guide wasn't what solved my problem, it was rich with information and gave me the tools I needed to get where I needed. I may attach a LED as you (and datasheet) suggest so I can see if ACT goes low during a programming attempt.

The “Size”, “Page”, and “SPI commands” will also auto-populate so you should not have to mess with them. Get the original data from a valid file previous saved, when opened with the tool you can confirm the data. The files are a bit of a mess as these are the result of creating the files on one computer and transferring them to another, doing a couple more edits, then making the git repository.To program a Bios using the CH341A programmer, you will need to download the CH341A programmer Software first.

El sistema de control de la cámara es una solución ideal para aquellos que no pueden tener un controlador o gatillo, ya que el sensor funciona con la mayoría de las cámaras de seguridad eeprom y otros sistemas de vigilancia tradicionales. To ensure the correct chip voltage, identify the chip model on the BIOS and look up its voltage requirements.

I got one of these today, and I noticed the PCB layout of mine is different compared to the one posted in this forum by jakeisprobably.Alguien me podria ayudar o darme alguna orientacion o enlace donde pueda encontrar mas info sobre el CH341B ? Run the programm, now there are no 95xxx type of eeproms available in the software, select 25xxx, with same capacity as your chip. Otherwise, if you are programming in circuit, simply make sure your test clip lead includes 10K resistors in series with the /HOLD and /WP pins.
