FALCOM RESSOURCE PACKAGE

What is a FRP

FRP is a file with a file ending *.frp which contains all needed binary and instruction to update a FALCOM AVL device. A *.frp file is basically a ZIP container with a given structure. The main idea is to have all needed files in one container - to prevent any mix of files which may not tested in this combination.

update process

unpack *.frp into local temp folder
parse content.xml
check device via $pfal,msg.version.complete
compare device class,type, major from current device with data from XML
if fit move on if not stop process here
check crc of *.bin
update *.bin via pfal in given mode (when compress is used compress before transmit)
check all packages transmit with ok
finalize update via pfal
device will reset
after reset check successfull update via $pfal,msg.version.complete

general update process

unpack *.frp into local temp folder
parse content.xml
check device via $pfal,msg.version.complete
compare device class,type, major from current device with data from XML
if fit move on if not stop process here
if defined a <pre> in configuration sent $pfal,Sys.Device.CfgUpdateMode to enter optimized device config update mode - if not skip next 2 points
update each pfal in any xxxxx_yyy.pre.conf one by one (timeout ~30sec. retry 3)
when all $pfal settings successfull transmitted sent $pfal,Cnf.Backup this will optimize the stored config and create a backup of the current configuration
check crc of *.bin
update *.bin via pfal in given mode (when compress is used compress before transmit)
check all packages transmit with ok
finalize update via pfal
device will reset
after reset check successfull update via $pfal,msg.version.complete
if defined a <post> in configuration sent $pfal,Sys.Device.CfgUpdateMode to enter optimized device config update mode - if not skip next 3 points
update each pfal in any xxxxx_yyy.pre.conf one by one (timeout ~30sec. retry 3)
when all $pfal settings successfull transmitted sent $pfal,Cnf.Backup this will optimize the stored config and create a backup of the current configuration
recommended to sent a $pfal.sys.device.reset
please note the "crc" / "sha512" for configuration is optional
