Description

The problem may have been @BIOS in general, or wrong BIOS flashed in, or it’s also possible sometimes retail BIOS does not work on some early ES boards so you have to stay on the ES BIOS and update it yourself with whatever changes you want. 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 tools Most systems in libreboot have to be re-flashed externally, using instructions on this and similar guides, the first time you flash. However, on all currently supported systems, it’s possible that you can re-flash internally when libreboot is running. CH341 is a USB bus converter chip which converts USB to serial port, printer port, parallel port, and common 2/4-line synchronize serial communication interfaces etc.

Take note of the ttyACMx. Flashrom is now usable (substitute ttyACMx with what you observed earlier). flashrom -p serprog:dev=/dev/ttyACMx,spispeed=16M If using BBB, you may have to use a lower speed than 512. You may also have to re-flash several times before it works fully. Start the pigpiod daemon, which the pigs utility communicates with to interact with the gpios: sudo pigpiodUse quality 60/40 or 63/37 lead+tin solder. Do not use lead-free! Lead-free is not suitable for hobbyist use such as this. Use quality rosin flux. Fluxes with an acid base should never be used. Amtech and MG Chemicals make good flux pastes. Use it in a dispenser tube. Some of these fluxes will contain adapic acid which has a low pH level, and it is simply used as a mild activator. So long as you clean the flux afterwards, you should be fine. 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. Mirror to the official CH341A drivers and used software, along with the documentation. I. Requirements A T12-D08 tip is being used in this photo, but a mini chisel, mini hoof or knife (e.g. T12-K) tip would be ideal.

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. EEPROM CH341A programmer – Read and write data to chip on Linux Software Requirements and Linux Command Line Conventions Category If flash chip is detected you may try reading (dumping) the flash contents now, or you can try flashing it with a new ROM. As per usual, this is a tutorial on the internet. Do anything you see here at your own risk. I am not responsible if anything goes wrong.https://www.digital-kaos.co.uk/forums/showthread.php/894410-Yamaha-Xmax-300-2014-pinout-need?highlight=xmax

Original UART applications are totally compatible without any modification in Windows operating systems. A second PC, to be able to flash the firmware from it to the the pc's bios chip you want to modify. It is important to use spispeed=512 or a lower number such as 256 or 128, because otherwise the BBB will be quite unstable. CH341SER_LINUX.ZIP– Linux driver source code for serial port (don’t need this one, it’s already included in kernels)

Schematic

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. Also may work if you use the 1.40-1.31Free version, you don’t choose ID in this, just chip size, then dump and see what if you get a good dump or not. There are also some other programmers and boards based on this chip. You can find most of them by searching "CH341A" on Banggood and AliExpress. Here is an overview of the programmers and development boards available: 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.

CH341H is only used for USB to 4-line interface, etc. (such as SPI). New designs are not recommended. CH341B or CH341F is recommended. KedarWolf - saving a BIOS in UEFITool does not convert anything, it simply adds .rom extension to whatever the original file extension is when you save or rebuild/save The best thing about the CH341a is that with other hardware, such as the Bus Pirate and Shikra I have found that I need to remove the SPI chip from the board to interact with it due to other circuits interfering with the targeted SPI chip. However, with the CH341a, I can just place a chip clip on the chip and dump the firmware without worrying about damaging the component by desoldering and soldering it on a breakaway board. We will be using the flashrom software which is written to dump, erase and rewrite these flash chips.Setelah icon dari Software muncul di desktop atau layar depan untuk cara menggunakannya Silakan simak Langkah-langkah berikuti ini; A good choice of soldering iron would be a T12-D08 or T12-K tip, on a T12 soldering station. KSGER makes nice soldering stations: In all such cases, flashing a new chip should be done using a breadboard, not a test clip. You will use 2.54mm dupont leads to connect your Raspberry Pi. For data lines, make sure that all wires are the same length, and about 10cm in length (don’t use longer lengths than this). In parallel port mode, CH341 provides an 8-bit parallel interface in EPP mode or MEM mode for input and output data directly without a microcontroller/DSP/MCU. As I described the BIOS component is very near from a set of 9 extras pins (not documented) and the clip can’t be properly clipped without doing some ‘manual mechanical adaptation’ on one side of the clip.
