Boot info/upgrade firmware

Např. při následující chybě při bootu často nezbude jiná možnost než flash firmware přes sériovou linku. Přenos je dost pomalý, ale naštěstí není firmware velký.

*** Warning - bad CRC, using default environment

Při boot zvolit možnost 0: Load system code then write to Flash via SERIAL.

Následně např. v Tera Term (Win) poslat firmware do sériové linky

Flash firmware přes USB Flash disk je rychlý, vyžaduje však mít z Vocore 2 vyveden USB konektor.

1. naformátovat USB Flash disk na FAT32
2. přejmenovat stažený firmware 20170211L.bin na root_uImage
3. zkopírovat root_uImage na USB Flash disk
4. připojit do USB portu Vocore 2 USB Flash disk
5. připojit a spustit Vocore 2 přes sériovou linku
6. zvolit možnost 5: Load system code then write to Flash via USB Storage.

Vocore 2 Lite má pouze 8 MB NOR storage. Proto je zapotřebí nějaké programy odinstalovat smazat něco z /overlay, co považujeme za nepotřebné, abychom získali místo pro instalaci motion a mohli zrealizovat stream z web kamery. Pro nahrávání videa by bylo zapotřebí nainstalovat ffmpeg, který mám kolem 5 MB a na interní storage jej nedostaneme. Proto by byl vhodnější Vocore 2, kde je 16 MB NOR storage. Nicméně je možné připojit SD kartu a ffmpeg umístit na ni a dále zrealizovat potřebné symbolické linky. Toto, ale nemám vyzkoušené.

# Codec to used by ffmpeg for the video compression.
# Timelapse videos have two options.
#   swf - Creates swf file with mpeg-2 encoding.
#     If motion is shutdown and restarted, new pics will be appended
#     to any previously created file with name indicated for timelapse.
#   mpeg4 - Creates avi file with the default encoding.
#     If motion is shutdown and restarted, new pics will create a
#     new file with the name indicated for timelapse.
# Supported formats are:
# mpeg4 or msmpeg4 - gives you files with extension .avi
# msmpeg4 is recommended for use with Windows Media Player because
# it requires no installation of codec on the Windows client.
# swf - gives you a flash film with extension .swf
# flv - gives you a flash video with extension .flv
# ffv1 - FF video codec 1 for Lossless Encoding ( experimental )
# mov - QuickTime ( testing )
# ogg - Ogg/Theora ( testing )
