In reply to Alif Ilhan. Unfortunately I don't know any method with the ESP8266.

Can I use the ESP8266 in place of CH340G? I know it is ridiculous but it is also a fun project for me. What I’m thinking is using esp-link to turn the ESP8266 as a UART bridge and then use it with the Arduino pro mini. But is that even possible? I have also read that serprog supports programmers over tcp, ip address etc….so is this a chance for me?

In reply to Gary. You can find the Flashrom and XLoader software on the Caddx Turtle flashing guide. Good luck.

Unfortunately http://ra.openbios.org/~idwer/flashrom/mingw/ is no longer active, is there another link for a precompiled Windows version?

The xloader download link is dead, but it is available elsewhere.

In reply to Anthony. There is flashrom firmware that works only on Arduino boards (Atmega). Odroid xu4 is different beast. Arduino costs only a few $.

Can i do this using an odroid xu4? Kinda in a pickle and have everything except the arduino

In reply to Fydo.

Hi, I assume you are trying to flash the firmware to the bricked Caddx Turtle board?
The line “serprog: Programmer name is “frser-duino”” shows that you have successful communications with the Arduino running Flashrom firmware.
The line “No EEPROM / flash device found.” shows that the programmer cannot communicate with the target serial flash chip.
You should double/triple check the wiring, usually the MISO/MOSI wires are mixed up. Also should be noted that serial flash needs to be powered by 3.3V.

Hello!! I’m going crazy. The arduino has already updated the serprog. But when reading the chip I get this:
c: \> mingw32-w64-flashrom-r1781.exe –programmer serprog: dev = COM9: 115200 –read flash.hex -c MX25L6445E
flashrom v0.9.7-r1781 on Windows 6.2 (x86)
flashrom is free software, get the source code at http://www.flashrom.org

Calibrating delay loop … OK.
serprog: Programmer name is “frser-duino”
No EEPROM / flash device found.
Note: flashrom can never write if the flash chip isn’t found automatically.

I have to say that I use an arduino uno. What I can be doing wrong?

Thank you!!

In reply to Josh. You dont need the DTR/RESET line, because UNO already has USB-TTL converter built in. Just make sure you power the DVR flash chip with 3.3V.
