1) copy a BSP image on a USB stick with dd (ex: core-image-lsb-sdk-jasperforest) 2) live boot from USB Notice regular hangs on usage. These hangs seem to be I/O related. Some usual hangs: -immediately after login prompt, insert incorrect user. Notice a 2-3 minutes system hang -issue "find / | grep if". Notice system hangs at some point during the search and resumes after a long time -conduct test cases like: https://bugzilla.yoctoproject.org/tr_show_case.cgi?case_id=207 https://bugzilla.yoctoproject.org/tr_show_case.cgi?case_id=205 I believe there was a bug/discussion on this in the past and it was blamed on poor USB read/write performance. The USB stick this was tested on has 20 Mb/s write 70 Mb/s read so I believe it has decent performance. Please note that I had same issues with recent sugarbay sato-sdk images and with n450 in the past(we don't have that BSP for testing here anymore). It seems to be an overall live boot issue.
I've only heard of these kinds of issues with very large live images, like lsb-sdk. I believe it is related to too little RAM. If these continue to be reported we may have to make some sort of explicit test during init.
This is still an issue on less powerfull platforms like MinnowBoard and AtomPC(tested with genericx86 image).
Also on lsb-sdk?
Need to test this on lsb this week.
I tested Minnowboard with a lsb-sdk image and it did not hang at all.
It seems most boards are working except jasperforest. Assigning to Lucian to help provide more info.
Had some trouble in the past with the jasperforest but it turns out to be because it is just a little more picky with the USB drives. The other images are tested regularly for live boot and there is no issue as far as I know. I think we can close this, and if there will be problems in the future open another one.
Closing this.
