agemio Posted October 7, 2015 Share Posted October 7, 2015 hi, I am th owner of a lamobo r1 card. Last days i'have tried more than 10 debian/bananian/ubuntu/raspian/openwrt image. Most of them work fine. Community image are often better than sinovoip one ... Unfortunatly, my sata HDD never work. I'm using a seagate 1TB SSHD. I currently using the armbian ubuntu image. At boot, the hdd spin up and stop, and ubuntu don't boot. If I remove the HDD everthing work fine. Anybody have a working hdd using the micro usb power port ? I use an ipad charger and a good one meter usb cable. Any help is greatly appreciated. If I should provide more details, please let me know Thanks agemio Link to comment Share on other sites More sharing options...

tkaiser Posted October 8, 2015 Share Posted October 8, 2015 I use an ipad charger and a good one meter usb cable. Does this mean you simply trust in charger and cable and believe they're able to deliver enough current/voltage? Or did you check it? On the R1 using an image with kernel 3.4.x it's pretty easy to get a clue if you run in undervoltage/undercurrent issues or not. Simply query the PSU using sysfs (unfortunately this still does not work with mainline kernel due to missing drivers) To get a clue which sysfs entries to query and what the problem is (undervoltage might happen only in situations when the system consumes more power) read this thread here: http://www.lemaker.org/forum.php?mod=viewthread&tid=8312&fromuid=33332 Link to comment Share on other sites More sharing options...
petrmaje Posted October 10, 2015 Share Posted October 10, 2015 Hi, look at label on the disk, there should be power consumption. I have tested R1 with ordinary mechanical disks with consumption <500mA. In this case is USB power strong enough. If your disk have consumption ~1A, USB is not enough.
