[SOLVED] Low cost Jtag Interface for OpenOCD (Arduino/STM32)

Post by rtek » Mon Apr 23, 2018 10:08 am

Hi all,

Sorry for my ignorance as a beginner in the world of JTAG, I have some S3C2440 chips to write the bootloader (some kb in size) and I would like to use some other card I already have to serve as interface,

I have Arduino Nano / Mega / Due and STM32F103C8T6.

Does anyone know if it is possible to use some of these cards as an interface,

So I can program the S3C2440?

Any tutorial on how to do this?

Thank you!

If you have a blue pill STM32F103C8T6,you can use dirtyjtag (https://github.com/jeanthom/DirtyJTAG) to convert it into a JTAG controller for UrJTAG.

If you want to use the blue pill with OpenOCD, the dirtyjtag page directs you to this page: https://github.com/zoobab/versaloon

I have not tried it.

Hello,

I think your alternative is very interesting,

However I have already managed to solve my problem,

With the help of a small Wiggler parallel port interface (SN74HC244) in conjunction with H-Jtag sorfware v3.0. I was able to program the SuperVivi bootloader, so with a serial cable and a USB cable the bootloader gave me the option to backup through the DNW.exe program.

My board is a old Mini2440 FriendlyArm.

Thank you for your attention!
