8310 & 7310 Dataloggers
Upgrading the Firmware
From time to time, Sutron makes available new versions of firmware, in order to introduce new
features and fix bugs. These upgrades are typically made available as downloads on the sutron
website (www.sutron.com/downloads/software.htm).
If your system is performing to your expectations, you may not want to upgrade, since there is
always some risk of introducing a new problem into the system. If you are unsure whether to
upgrade, and would like to know more about the contents of a particular upgrade (what it adds
and what it fixes), contact Sutron Customer Service and request the engineering bulletin for the
upgrade.
There are a few methods to upgrade the firmware in the 8310:
Application, kernel, loader, and
micro monitor
WHEN UPGRADING v1.1.x TO ANYTHING HIGHER, YOU MUST UPGRADE THE LOADER!!! SEE,
“Upgrade the Boot Loader”, BELOW. AFTER UPGRADING THE LOADER, UPGRADE THE
APPLICATION AND KERNEL.
DO NOT DOWNGRADE TO v1.1.x FROM A VERSION HIGHER THAN v1.1.x WITHOUT
OFFLOADING YOUR DATA FIRST! DOWNGRADING TO v1.1.x FROM A HIGHER VERSION WILL
RESULT IN A LOSS OF DATA ON FLASH DISK!
SD CARDS ARE SUPPORTED. SDHC CARDS ARE NOT YET SUPPORTED.
