  1. Hello, I just received an Analog Discovery 2 and upon trying it out I got this error : PLL not locked. Unknown speed grade 0 FPGA-PLL not locked USB: 5.06V 112mA AUX: 0.00V 0mA Device:AD2 rev:3 cfg:2 WF:3.19.30beta I already looked at : And many other posts... Things I've tried : - Reboot with AD connected and disconnected - Changing cable - Changing USB port - Changing version (the WF version on the screenshot is beta but I've tried with latest stable) - Changing OS (windows and linux (ubuntu Jammy) with the 2 different version And finally I read about maybe not enough power threw USB so i plugged externad 5 volt on an ATX power supply (500W) and got the second capture (2222.png) showing that indead it was receiving external help... still same errors... I should also mention a green led is blinking arround twice per second as I try to calibrate the device and continues for a while... I know these kind of problems regarding PLL seem quite common I couldn't find a post with the same exact errors and I'm out of ideas to try... Thanks for youre help in advance Maël
