Could you post a screen dump, please? That photo is extremely hard to read.

I see you found some software; which one?

You seem to be powering the display board, at least the 3.3 V part of it. My guess is that you haven't connected the wires correctly (3.3 V and ground must be correct, so it would be the other two), or you need to try the other protocol. I don't know ARMs at this level. It's possible that it just doesn't know the GD chip.

Can you set the device to an STM32F105, perhaps in the drop down box in the toolbar?

I have set to stm32f105 and still error. I have checked wires

Use GD-Link for GD32, not work with ST-Link, also need aplication for GD32

i programmed GD device with jlink interface

Thanks for the help. Will this one work? 
 

Yes, can try

Ok going to buy this one locally and try tomorrow. Can u share steps? 

Pls check first application if ur cpu is 100% compatible with this interface. I programmed stm32f103

i am not working very much with this interface, only one time in one growatt ongrid

you have firmware to write in microcontroller?

Ha ha, in this moment I received for repair display with GD32 😂😂

This is different MCU, is GD32F305VET6, but, i read firmware wit ST-LINK and Visual ST without any problem, i select STM32F107 and work good. This is display with touch buttons, not work for you, for you i think work firmware for STM32F107, and i have firmware for you.

Mine is the same as that one!

I have recieved the jlink. How is the wiring to the control panel? 

I think I have entered the chip. What now?

Yes, that actually looks like the start of the bootloader. Well done!

Now you find the menu command to read the flash image, and save it to a hex file. Please post that hex file here as an attachment.

Nearby, you will likely find a menu command to read a hex file and program it to the device. But you'll have to carefully set things up before pressing the "burn baby, burn!" button. Also, we have to choose the right hex file for you to burn. I'll have to review your posts to make that decision.

first, do backup!

after, what is problem with ur display?

i put here full firmware with bootloader, after do backup, erase chip memory, and write this file

12.13_wifi_display_detasabil.hex

I tink its this?

original.hex

To download is like this? 

yes, after erase chip, after write entire chip

But how do download the oriinal irmware rom chip?
