I had quick look at dump.

The bytes are swapped on your dump so when I get hex conversion it comes out backwards:


00000000  f0 0b 00 01 00 00 00 00  f0 0b 89 04 00 00 00 00  |................|
00000010  f0 0b d0 04 00 00 00 00  f0 0b f3 04 00 00 00 00  |................|
00000020  f0 0b dc 04 00 00 00 00  f0 0b 83 07 00 00 00 00  |................|
00000030  f0 0b ed 08 00 00 00 00  f0 0b d6 04 00 00 00 00  |................|
00000040  f0 0b d8 04 00 00 00 00  f0 0b da 04 00 00 00 00  |................|
00000050  f0 0b f1 04 00 00 00 00  f0 0f b0 08 00 00 00 00  |................|

There are also lots of "gaps" in your dump.

So need to look at how to "flip" the bytes so can do a sensible diff of dumps.

This might take a bit of manual reading ...

Hi Jwhat,
Yes, I mentioned in my original post they are big endian encoded, so I had to word swap sections on little endian platforms to view them.  But I used a shareware app for just this section to word swap.  I didn't find a easy way to do that.

I wanted to see the other variables in the struct compared to yours as well, I knew the CPU frequency and hub speed were the same...was curious about the other things.


Endian Conversion Instructions:
Code:
xxd -e -g2 AM29LV160DT@TSOP48_front_2_fuel_MB_PROM_flash.BIN | xxd -r > PROM_Temp.bin
xxd -e -g1 PROM_Temp.bin temp_Le_prom.hex
