Hi,

Is it printing anything when you power on?
Can you connect to the camera via ssh?

>>>>>>>>>>>>>    - from PC terminal window:
>>>>>>>>>>>>>
>>>>>>>>>>>>> ...$ ssh root at camera-ip
>>>>>>>>>>>>>
>>>>>>>>>>>>>
>>>>>>>>>>>>>    - Edit the /etc/php/php.ini - you will see that the limit

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

>>>>>>>>>>>>>
>>>>>>>>>>>>> root at elphel393:~# sync
>>>>>>>>>>>>>
>>>>>>>>>>>>>
>>>>>>>>>>>>>    - restart web server (or reboot)
>>>>>>>>>>>>>
>>>>>>>>>>>>> root at 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

>>>>>>>>>>>>>
>>>>>>>>>>>>> [83470.681265] sd 6:0:0:0: [sdb] 7806976 512-byte logical
