It's hard to say without seeing the actual bootlog. If you boot from
recovery card, uploaded and flashed *boot.bin*, *u-boot-dtb.img*,
*devicetree.dtb* and *uImage*, but not rootfs.ubi - I would expect some
kind of "kernel panic" on any of the boards.

The Note in my previous letter addresses this problem - the upload limit in
php on the recovery card. There are 3 options:
1. Copy rootfs.ubi manually

   - http://camera-ip/update_software.html
   - upload all files except rootfs.ubi
   - from PC terminal window:

...$ scp rootfs.ubi root@camera-ip:/var/volatile/html/update/


   - go back to http://camera-ip/update_software.html - hit 'verify' and
   you should see rootfs in the list

2. Increase php upload limit of the recovery image on the card

2a. when boot from the recovery card:

   - boot from the recovery card
   - In the browser: http://camera-ip/phpinfo.php - find: *post_max_size*
   and *upload_max_filesize *- they are 128M probably.
   - from PC terminal window:

...$ ssh root@camera-ip


   - Edit the /etc/php/php.ini - you will see that the limit is less than
   rootfs size - increase it so it will read:

upload_max_filesize = 512M
>
>
>
> post_max_size = 512M


   - sync command just makes sure changes are stored on the card.

root@elphel393:~# sync


   - restart web server (or reboot)

root@elphel393:~# /etc/init.d/lighttpd restart


   - In the browser: http://camera-ip/phpinfo.php - check if those
   variables have changed to 512.
   - In the browser: http://camera-ip/update_software.html - upload rootfs,
   and other files as well

2b. If you have a linux os and a usb card reader - insert in PC, mount
rootfs partition and edit /mountpoint/etc/php/php.ini as in 2a.

3. Update recovery card. This option requires linux os and a usb card
reader... and a few programs installed: parted, kpartx

   - insert the card - check with dmesg the device name, you will see
   something like this:

[83470.681265] sd 6:0:0:0: [sdb] 7806976 512-byte logical blocks: (4.00
> GB/3.72 GiB)
> [83470.686369]  *sdb*: sdb1 sdb2

If the card is discovered by PC as *mmcblk0* then the script will not work
- as I didn't cover this case.

   - Open konsole, using 'cd' navigate to write_bootable_mmc.py in the
   unpacked firmware image (elphel393_20180130/mmc/)
   - ...$ sudo ./write_bootable_mmc.py */dev/sdb* (sdb as reported by dmesg
   - this is important)
   - After the script is done - boot this from this card.

Hi Oleg,

Thank you for your help. However, I'm still having the same problem. On one
of my elphels, when I use the recovery card it works fine but when I remove
the card the feed is very laggy. Do you know what the issue is? Also, when
I uploaded the files to ipaddress/update_software.html the rootf file would
not upload. I don't know if that is a problem.

Thanks,

Hi Oleg,

Thank you for your help. However, I'm still having the same problem. On one
of my elphels, when I use the recovery card it works fine but when I remove
the card the feed is very laggy. Do you know what the issue is? Also, when
I uploaded the files to ipaddress/update_software.html the rootf file would
not upload. I don't know if that is a problem.

Thanks,

Mohamed
