	06A906032AC, reading flash, cheksum errors? « on: June 16, 2011, 02:39:10 PM »

car: Audi A3 1.8T quattro 150hp -00.
ME 7.5(?)
06A906032AC

Thought id try to read this ecu, and ive validated the 29f800BB memory layout = ok.
started the flash read, and everything seems to work fine up till ~57%, flash checksums = ok.

but, from 58% and onwards, it keeps saying flash checksums do not match, retrying.. 3 attempts, and then skipping and continue to read.
what happens here? does this affect the bin-file produced.. or does it still match the contents of my ecu-flash?
the whole procedure took ~47 minutes..

ill attach the produced bin-file, if someone with more knowledge would be so kind to have a look at it.. Undecided

@ sn00k :

Thanks for posting this file. I was looking for it.

You chose to use the 1mb flashconfig but the flashrom itselfe is a 512kb one !

Therefore the act-up i presume.

A simple hex-editor correction does the job. Readout is 100%.

Corrected file added

Cheers,

PvL

I think that ECU is ME7.1 - 512kb so just use 400BB layout.

file is definitely ME 7.5.

as youve noticed it is a 512kb file, i figured this out months back, but i never got around to correct the file and upload it here, so thanks pvl for doing that =)

i have better cables, tools etc for reading ecus nowadays, i remember reading this file took like FOREVER.. Grin

If its 512kb then its narrowband.

yes, it is very much narrow band, as alot of other ME 7.5 ecus, in fact ALL pre -01 are narrowband in europe.
5.9s in early 1.8ts and then 7.5 in the later 99 and 00 ones.
