I have a microcontroller project that uses an Atmel ATmega128 micro; a little-endian architecture. It runs a firmware that I wrote in C with the AVR glibc. This program stores a structure in the onboard EEPROM of the chip.
I have a script to convert a dump of this EEPROM to a file format that I can use in my analysis tools. The first member of each record is a 32bit floating point number. My script uses unpack to get the members of the structure and put them in a format that I can more easily analyze (in Matlab, etc.)
The problem is that my script runs on Sparc workstations; which are big-endian, while the ATmega chip stores data in a little endian format. How can I force

unpack(" f v v v", $record);

to unpack the float in the proper byte order?
