PLS Problem

Hi,

i have used PLS many time and many.

Now PLS does not work any more. Still this problem:

 

Message from component 'PpcJtagTargIntf' :
Can't connect target !

Message from component 'PpcJtagTargIntf' :
No JTAG client found !
Please check:
- target power supply
- JTAG cable connection
- target configuration

I have done in folder 

C:\Program Files (x86)\pls\UDE Starterki5.2\Driver\JtagUsbDriver 

with with Administrative rights UninstallPlsUsbJtagDriver.bat and then InstallPlsUsbJtagDriver.bat

I have load VCP for all combination:

 only on SPCxxxA , only on SPCxxxB, both on SPCxxxA  and SPCxxxB or no VCP.

I have both version on UDE STK 2021 64bit and SPC5-UDESTK 5.02.04.

I have 2 PLS and many boards (both custom and official discovery SPC56).

I try to change laptop but still the same

Never lucky.

Please can somebody help me!!

Thank you in advantages!

I have solved the problem. 

With a third PC i see that PLS was working and in the "Detail Tab" all was egual to my pc except for "INF Name"

The working PC has "oem30.inf" and not working PC has " oem176.inf"

So after some google search i found these link:

https://answers.microsoft.com/en-us/windows/forum/all/windows-11-version-22h2-for-x64-based-systems/6031bb17-d7b4-4d17-913e-b414f295cadf

 

So i have done:

Click your Start Button, then just type powershell

Right click PowerShell in the resulting list and select 'Run as Administrator'

Run tis command and press Enter:

pnputil /delete-driver oem45.inf /uninstall /force

Run tis command and press Enter:

pnputil /delete-driver oem176.inf /uninstall /force

Run tis command and press Enter:

pnputil /delete-driver oem4.inf /uninstall /force

Close PowerShell and restart (not shut down) your PC.

Then i have re-install the PLS drivers and it works again!!

My god...

I hope this help somebody
