https://community.nxp.com/t5/Power-Management/KITVR5510-amp-FRDM-K82FD/m-p/1673173#M2739 <P><FONT>Hello NXP team,<BR />I have already purchased the VR5510 kit and have successfully completed OTP burning and normal communication on the GUI. But I don't know why. When I tried to power it up again a few days later, I found that my package couldn't communicate with the GUI anymore. It was just that I couldn't click the GUI START button. My firmware is the latest and the GUI version is 8.0.0. I haven't had this problem for two weeks since I bought it, and I have a 12V power supply and a computer USB power supply, so there won't be any overvoltage issues.<BR />Thanks in advance for any help</FONT></P> Wed, 21 Jun 2023 03:16:04 GMT Oliver2 2023-06-21T03:16:04Z https://community.nxp.com/t5/Power-Management/KITVR5510-amp-FRDM-K82FD/m-p/1673173#M2739 <P><FONT>Hello NXP team,<BR />I have already purchased the VR5510 kit and have successfully completed OTP burning and normal communication on the GUI.
