# Description:	Pre-installation script for Jade SWDL of bitmap images file via CAN
#
# This script is downloaded and executed before any application files.
# It can be used to check flash drive integrity, predelete old files etc
#
# Also, the execution time of all commands in this script must not excede 5 min
# (VBF generator appends a minimum of 6 EOF blocks allowing @55s each block)

# Can normally safely erase flash partition while a CAN download is ongoing, since 
# the erase takes 5s/MByte whereas CAN download takes 60s/Mbyte (or 24s/Mbyte 
# when compression is used). However, the raw bitmaps partition is a special case,  
# since compression ratios of up to 95% are common for images. That means the  
# download rate is effectively 3s/Mbyte i.e. FASTER THAN THE ERASE !
#
# FORTUNATELY, for downloads on top of X351/L322 releases after 21st August 09, the  
# post-download scripts use pidin and grep to checks for completion of the flashctl
# erase process.
