ZGW2 dead can be rescued?
Hi all,
I've killed a ZGW2-High by flashing a wrong gatewaytable. Now zgw is un-responsive ofc... If I erase the eeprom (25lc256) zgw responds to very limited set of commands and it's stuck in bootloader  Is there a chance to revive this one? Is able Chinese Xprog to read/write SPC5668? And if so, has anyone the pinout to avoid the hassle of reballing it? I like Objective-C |

Desoldered the MCU and traced some pins...
Now waiting 3 months for the Chinesium OSJTAG MPC/SPC tool to arrive... Really curios if the chip is locked or not 
I like Objective-C |

But wrong in being corrupt and it was on purpose because I want to route some diag messages to FA-CAN and Ethernet. It's mostly trial and error, and by trial and error might mean a lot of ZGWs bricked. Not a viable solution. Project on hold until the CodeWarrior tools arrives Yes I have spare ZGWs, but not going to brick them all lol I know about _STEUERN_ADD_DIAG_ROUTING, but I want a persistent way. And I know that by using a can transceiver you can send on dcan: 6F1 0x10 0x10 0x08 0xBF 0xFF 0xFA [ECU ID] [FLAG1] 6F1 0x10 0x21 [FLAG2] [FLAG3] [FLAG4] [FILL BYTES...] But... implies a transciever I like Objective-C |

RE: ZGW2 dead can be rescued?
Gateway table becomes via vehicle configuration (FP, SVT soll), not with flashing. Or wish make custom variant?

Want to add on F01 DKombi2 on FA-CAN and remove it from B-CAN as it's useless there. Also want to send the two ZGW Network messages 0x510. Not only the SP2009, but the 2015 one too, directly from ZGW. How can FA + SVT help me in my case? Yes DKombi2 is pretty functional in my F01 at this stage. Gotta sort the EPS issue tho. It expects electric power steering but I got servo, but that's a problem for another day. Edit: Sorry, FP... I like Objective-C |
