5.14 Firmware update
n There is the opportunity to execute a firmware update for the CPU
and its components via MMC. For this an accordingly prepared
MMC must be in the CPU during the startup.
n So a firmware files can be recognized and assigned with startup,
a pkg file name is reserved for each updateable component an
hardware release, which begins with "px" and dif
fers in a number
with six digits. The pkg file name of every updateable component
may be found at a label right down the front flap of the module.
n After PowerON and CPU STOP the CPU checks if there is a *.pkg
file on the MMC. If this firmware version is different to the existing
firmware version, this is indicated by blinking of the LEDs and the
firmware may be installed by an update request.
