The 2 leds (green and yellow) are on. I'm using power from a battery
without the traco board. This is what I did with the 1st board. I also have
the traco board if i need it which is 18-75V. I haven't changed anything in
minicom. I just flashed with the recovery card in, removed it, and tried to
connect with minicom but I can't type anything in.

>>>>>>>>>>>>>>>>
>>>>>>>>>>>>>>>> 2a. when boot from the recovery card:

>>>>>>>>>>>>>>>>    - boot from the recovery card

>>>>>>>>>>>>>>>>    - from PC terminal window:
>>>>>>>>>>>>>>>>
>>>>>>>>>>>>>>>> ...$ ssh root at 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

>>>>>>>>>>>>>>>>
>>>>>>>>>>>>>>>> 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

>>>>>>>>>>>>>>>>    - 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

>>>>>>>>>>>>>>>> If the card is discovered by PC as *mmcblk0* then the
