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
