Hello,
i want to use an ARM Juno i have. Unfortunately, when i plug a USB 3.0 usb stick with ext3/ext4 format i have the following traces :
ext4 :
[ 4.004845] sda: sda1[ 4.009631] sd 0:0:0:0: [sda] Attached SCSI removable disk[ 4.072965] EXT3-fs (sda1): error: couldn't mount because of unsupported optional features (240)[ 4.084337] EXT2-fs (sda1): error: couldn't mount because of unsupported optional features (240)[ 4.110636] EXT4-fs (sda1): mounted filesystem with ordered data mode. Opts: (null)[ 4.118262] VFS: Mounted root (ext4 filesystem) readonly on device 8:1.[ 4.126529] devtmpfs: error mounting -2
ext3 :

Can anyone help me to boot up my ARM Juno card please. Thank you very much
PS : I took two different usb sticks. 1 transend and 1 sandisk with the same problems
Hi,
Would you be able to provide a full kernel log? There's not enough information to go off in excerpt you've given.
Also, which deliverables are you using on the board? We recommend you use the Linaro deliverables - See this document for step-by-step instructions. These deliverables expect the root filesystem to be on the second partition of the USB stick. Has your USB stick been partitioned in this way? Which filesystem are you using?
Thank you for the answer,
I have the full kernel log. Please take a look to the attached txt file.
I'm new on the ARM Juno Board then i'm not totally aware of what i have to do to boot up the card, thank you very much for the link. A guy told me that some USB sticks didn't work on the ARM Juno. If you have any information on what USB stick work on it it will be very usefull for me.
For the linaro delivrables, where should i put the files ? into the internal MMC memory or on a external usb stick ?
Thank you.
Ah, you appear to be using very old deliverables, probably the ones that came with the board?
I recommend you follow our instructions here on how to install the latest deliverables onto the board. This also includes instructions for properly setting up your USB stick, which you've not done (your USB stick only has one partition, whereas the latest deliverables will be expecting to find the root filesystem on the second partition of the stick).
I hope that helps,
Ash.
Hi Ash,
Even one partition is fine if that partition is pointed in cmdline via root= and has proper filesystem.
He seem to have passed right cmdline, but just missing /init in his root file-system.
