I have worked out the 32bit (CS2) checksum.
See attached document.

Hello,

I've tried your solution for CS2 but it's not working. I've done all calculations on joined dump but didn't works. I've tried all combinations RefIN, RefOut, with end xor ffffffff, end xor 0, byte swap... thanks for your help

Then you're making a mistake somewhere Sad

If you can get CS1 working, then CS2 should be no problem. Just change the data area and the start value as suggested in the document.
(Please note that you use correct endianess!)

This was posted on another forum for the members there... And if you have the same username there then you didn't even give a thanks to the original poster. Or asked him... Not nice.

Sure does it work and no, there is no bin collected. Why should anyone collect bins from edc17? You can not decode them without the correct flashfile from micro and they are useless.

There is a collector for bosch RB4 and RB8 cluster and those are useless without the encryption mask from the MCU in the cluster.

Np. EDC17 has a Tricore controller with internal eeprom inside micro. Post your dump Flash+EEprom (in a new thread) and i or somebody else can calc this for your.
