FX2 FW: conversion from Intel HEX to DVB USB "hexline"

FX2 FW: conversion from Intel HEX to DVB USB "hexline"

[Antti Palosaari]

Is there any simple tool (or one liner script :) to convert normal Intel 
HEX firmware to format used by DVB USB Cypress firmware loader?

Or is there some other way those are created?

Loader is here:
dvb-usb-firmware.c
int usb_cypress_load_firmware()

I'm sure that you have found something yourself in the meantime, but I used 
the attached script to convert .hex to binaries.

HTH,

Many thanks!

Actually, I was just started to write similar Python script! You got 
maybe 15min late but still 15min before mine was ready :)

Format was nothing more than convert ASCII hex values to binary bytes 
and stripping out all white spaces and Intel HEX start code ":".

Why it was initially converted to binary and not used Intel HEX as it 
is? I think you know, as a original author, history about that decision?

Antti

Because doing string-parsing and evaluation in the kernel is something I 
usually  avoid. And it can't sure be done within 300 bytes (the size of the 
perl script). Also the .bin is smaller in term of size compared to the .hex.
