LPC1115 Rev A Driver communication issue with Windows11

[CKGrech]

I have an LPC1115 Rev A. It is required to install the massDfu64.sys driver on the PC for communication. However due to Memory Integrity in Windows 11, the driver is not allowed to be installed. What can I do to work around this without turning off the Memory Integrity feature, please?

Thank you

Hi @CKGrech,

How are you trying to install the massDfu64.sys driver? Through the LinkServer.exe installation file? Try launching the installation wizard as an administrator, and let me know if that helps.

BR,
Edwin.

Hi,

When the LPC1115 is connected to the PC it usually attempts to install the driver, but it doe snot work. Moreover, I do not have the LinkServer.exe.

Hi @CKGrech,

You can find the link server installation executable on the following link: LinkServer for Microcontrollers | NXP Semiconductors

Please download it and open it with administrator privileges.

Let me know if you continue having issues even after installing this.

Hi,

I installed Link Server and when I opened it started LinkFlash, and when I press probe it tells me "No Device Connected".

Hi @CKGrech,

Do you see the same behavior on MCUXpresso IDE? Or what IDE where you using at first?
