As you observe you can see that this particular router looks to have been reset before it was taken out of commission and sold since it has what looks like default values. Lost_N_BIOS So essentially what happens is that the Board doesn’t start at all upon pressing the power button.
Take note of the ttyACMx. Flashrom is now usable (substitute ttyACMx with what you observed earlier). flashrom -p serprog:dev=/dev/ttyACMx,spispeed=16M Basically, the Raspbian project, now called Raspberry Pi OS, put in their repo an update that added a new “trusted” repository, which just so happened to be a Microsoft software repository. They seem to have done this for VS Code, but the problem here is that it gave Microsoft free reign to define whatever dependencies they liked (as per apt-get rules), and every time you updated, you would be pinging Microsoft servers. Do you think that is strange? CH341 is a USB bus convert chip, providing UART, printer port, parallel and synchronous serial with 2-wire or 4-wire through USB bus Now, try to read the chip again with the software CH341A programmer v1.30 (see the 4th part of the guide, above). Chances that it works this time are the largest possible. There are no more problems of stories of insufficient or excessive tension. https://www.digital-kaos.co.uk/forums/showthread.php/894410-Yamaha-Xmax-300-2014-pinout-need?highlight=xmax
Schematic
Ensure that all the joints are perfect. A good solder joint is shiny, and with concave fillets where the solder has flowed. Observe: 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.
Mirror to the official CH341A drivers and used software, along with the documentation. I. Requirements When you’ve placed the diode, ensure that VCC on the chip is isolated from all other components on that board, which share the same power rail. Further, ensure that the pull-up resistors for WP/HOLD are only connected to the side of the diode that has continuity with the VCC pin (this is important because if they’re not, they won’t be held high while doing ISP flashing, even if they’re still held high when the mainboard is fully powered on). NOTE: debian, arch or void can be written instead of ubuntu2004. the debian script is also applicable to newer ubuntu versions ./update trees -b flashrom ISP means in-system programming. It’s when you flash a chip that is already mounted to the mainboard of your computer that you wish to install libreboot on.If your computer restarts constantly, after trying to flash the Bios via M-Flash and no standard solution worked: reset the CMOS, unplug the hard drives, change the location of the memory modules, remove the motherboard battery, try to access Dos through a bootable USB key to reinstall the Bios, then you just have to reprogram the Bios with an external integrated circuit. CH341PAR.ZIP– archive containing driver files for interface mode and API (header and library to access the device and use any protocol you want). If you go for a SOIC8, mounted it to the SOP to DIP adapter (208mil 1.27mm one) and solder 2.54mm headers to it. You could put the 2.54mm pins in a breadboard, then solder the chip to the adapter PCB and mount that to the pins on the breadboard, to keep it aligned, and solder that. Whith the PCB on the pins, and the pins in the breadboard, push the pins inwards a little bit.
NOTE: Linux and BSD systems (Android, MacOS, iOS, Ubuntu, ChromeOS etc) are sometimes called "UNIX-like" operating systems. Low cost, convert the original serial port peripheral devices, the original print port printer, and the original parallel port peripheral devices to USB directly. Now run (as root) dmesg -wH. When you plug in the Pico, a line like this will appear: [453876.669019] cdc_acm 2-1.2:1.0: ttyACMx: USB ACM device I'm a total noob, just found a laptop in the trash and wanted to try to fix it, after some research the issue was related to a corrupted BIOS, so I found a DUMP for my laptop online and bought the CH341A programmer. I hope this will help someone, like it did for me. I must say, this is not my solution, I am just sharing it with you. I used this programmer with success to read and write to 95128 EEPROM.
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. Do not connect the power source until your chip is otherwise properly wired. For instance, do not connect a test clip that has power attached. Then you need to install it in the Programmer, making sure the notch faces the same way as indicated in the white diagram in the bottom right corner: It’s about Dell, but maybe those commands will help you with flashrom (or may later or previous he discusses flashrom version used)
Great Deal
