Problem with custom Application Template

[MLind]

By following this guide (https://touchgfx.zendesk.com/hc/en-us/articles/115002741432-Create-custom-Application-Template) I have made an custom application template for our hardware. I'm able to select my application template in TouchGFX Designer (4.10.0) but when I press CREATE I get "Downloading Application Template failed, check your internet connection and try again". Does anyone have any suggestions?

Hi @Community member​,

Do you have a designer log file i can take a look at? I haven't encountered this issue before creating application templates.

Hi @Martin KJELDSEN​ 

I also did my first attempt to create a custom application template for the first time in order to get used to and also verify the procedure. Here is what I did and what I get in the end:

1. I did started a project with an a red background using a full screen box for the board STM32F429I_EVAL which I have.

2. Verified the project by run it on the simulator and also on the Target.

3. Then generated the code.

4. Followed the procedure described on the page https://support.touchgfx.com/docs/development/touchgfx-hal-development/scenarios/scenarios-create-at/#describe-application-template. Applied successfully and produced the .tpa file. Here is the .json file after I editted, * marks the lines I editted:

{
 "Meta": {
 "Url": "http://packages.touchgfx.com/V2/STM32F429I-EVAL/STM32F429I-EVAL-1.0.0.zip",

 }
}

5. Copied the .tpa generated into the related directory. Run the Designer and tried to start a project selecting my template. Here is the result:

 Also here is the Designers' log file:

TouchGFXDesigner.log

Strangely it is mentioned about STM32F769I-Disco not the one that I worked with which is STM32F429I-EVAL!

We have couple of our own custom boards which we use commercially and it will speed us up a lot if we use custom templates to produce new products.

So any help very much appreciated =)

Thanks in advance.

Hi,

Now I have done the process again and figured out the problem. The name you set in the .touchgfx file ("name":"MyName") controls the name of generated files and the final .tpa file (MyName-1.0.0.tpa) and hence the name of this file cannot be changed.

That's good news. Glad you figured it out. Anything you need help with?
