Please test. Sorry for a big message like this. Only after sending, I realized that the extracting tool were so badly optimized. Anyway, I've optimized the script. It has now only 14Kb. It basically writes the header for each firmware, with the firmware type, supported standard IDs and its size. Then, it copies the entire firmwares from HVR driver. Something like this: # # Firmware 9, type: STD FW MTS (0x00000004), id: PAL/BG A2/B (0000000200000007), size: 169 # write_le32(4); # Type: MTS (0x00000004) write_le64(8589934599); # Id: PAL/BG A2/B (0000000200000007) write_le32(169); # Size: 169 write_hunk_fix_endian(865592, 169); # Get the firmware from position 865592 Since ID has 64 bits, I suspect that this perl script works fine only on 64 bit kernels. Probably, we need to use Math::BigInt for this to work on 32 bit kernels. > > Cheers, > Mauro Cheers, Mauro _______________________________________________ linux-dvb mailing list linux-dvb@xxxxxxxxxxx http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb
