Introduction: Reviving the DSO138 DIY Digital Oscilloscope Kit

My DSO138 DIY Digital Oscilloscope Kit had a trouble in the firmware update. And it did not work anymore.

Even following these instructions it was not possible to revive the DSO138 DIY Kit ( http://www.jyetech.com/Products/LcdScope/DSO138_oscilloscope_upgrade.pdf )

Step 1: Solution

After several attempts to fix the problem, here was the solution: My step is to just download stm32flash (https://sourceforge.net/projects/stm32flash/) and using the command:

Stm32flash -w 113-13801-061.hex -v -g 0x0 COM3

COM 3 is my USB TTL converter.

Step 2: Tools

DSO to USB TTL connections:

GND to GND

TX to TX

RX to RX

If it doesn't work, reverse the connection with the TX and RX pins.

Staying like this:

DSO to USB TTL connections:

GND to GND

TX to RX

RX to TX

To program, plug in the power supply.
