USB Access

[Hitesh]

When secure manager is installed, USB is not working. Can you share me the process to activate USB.

Hi @Hitesh_Aratek ,

If USB enumerates as DFU one possible reason could be that you set the PRODUCT_STATE as CLOSED.

Normally, after Secure Manager installation, the product state is TZ_CLOSED, meaning you can access to the non secure part of the flash.

Then you can download and debug your software.

Are you able to use the debugger and see if your sorfware executes as expected. I mean, you launch debugger, downloading the application then run it and break. Are you in a known place in your application ?

If you have set product state to CLOSED, then the STuROT will jump to embedded bootloader. In this case the device enumerates in DFU.

If you have not closed the device, please proceed with debugger to understand what it is doing.

 Best regards

Jocelyn

Hello @Hitesh_Aratek ,

I'm sorry, I don't understand your statement. What do you mean by reaching the target output?

Best regards
