Linux freeze in the end of the boot process



Hello to everyone.

I try to boot linux on ZYBO board. I follow the instruction: https://reference.digilentinc.com/zybo:zybo:zybotguide

But in the end of the boot process everything freezes.  And I can't understand what am I doing wrong.

Here are several last lines of the boot process.

ALSA device list:                                                                                                 
  No soundcards found.

init: ureadahead main process (588) terminated with status 5



What puzzles me most is the fact that several days ago everything worked fine...

Hi Art, 

I wasn't able to duplicate the issue. I did just update a link in the Zybotguide for linaro. The link now opens the correct version of linaro for the Zybo. If you use a different version of Linaro that might be the issue. While i do more research would you check and see if you used the right version.

thank you,

Just an update on this. Today I noticed that my power source has only 550mA output, which is more or less equivalent to what the USB port can deliver. In the Zybo Reference Manual it says I should have at least 2.5A, so it may be it (even though I am not using HDMI). Whenever I have a decent power supply, I will post an update of my experiments.
