I like to know if I can clone a GD32F150.
I have 2 nos shorted ones and 1 working one.
Is it possible ?

 

What exactly would cloning such a part involve?

 

Dunno !
Just asking around if it is possible to take hex to program another chip.
If it can be done, may be get the hardware to do it.

 

If the code protection has been enabled then it's most unlikley you could read the code in the chip.

Problem is that you won't know until you try, and you'll be out the cost of the programming hardware.

 

I can deal with the cost.
Looking for a HW that can do this.
Any idea on the hardware.
It's a ARM chip , right ?

 

Again - if the chip is in a commercial product, it WILL have code protection switched on, and you are wasting your time.

Right. and ...
This should be the data sheet.

I guess I don't get the clone part?

Right now I have 3 units to fix.
2 of them had shorted uC. One is working.
Issue is there are couple of more on the way.
I can get the chip but the firmware is the issue.. So I was thinking out loud.
Extract the hex, program a new one and solder it.

I know.

 

OK so you have some boards that use the mentioned uC. Now if some board manufacturer used that uC and loaded a proprietary boot loader or other software routine there is no way you are going to be able to do this. I know of no way you can extract/download whatever is on your one working unit. Correction, no way I am aware of anyway.

I am willing to try, assuming there is no boot loader and not protected.
What HW am I looking for ?

 

 

ST-LINK/V2 Or j link
raspberry pi can even be used there some cheap J link there education ones never tried one I have the ST-link but there cheap[ clones out there
