E54 Tunerlock Help

I believe we have E54 working properly. I've sent you a test version if you want to try it.

I am very sorry for being late to the game. Thanks everyone and In-tech for all of this. I appreciate it so much. I did end up failing my customer.. I wasnt able to get it to boot pin read. But I have ordered a spare E54 to play on.
Antus, will the beta test version be available soon with E54? Thanks much!

Perhaps. We have one pcm reading and writing properly, but the other test pcm that had something wrong with the bin wouldnt erase. We put the bad bin on another pcm, then it suddenly couldnt erase either. With testing more things that one bricked. rjdrew is posting it half way around the world to me now (2 weeks post?) then i'll try and figure out bdm and bdm cfg file (if needed) and recover it then repeat the process and try and improve the kernel so it doesnt have the same trouble with the erase step. All of this may take some time, so there probably wont be a public beta for at least a few weeks, maybe more. I can share the private beta with you, but it might brick and testing wont help as there will be more changes now before its done.

I have successfully used the ground method on these ecms in the past. I do not remember which pin. I took a p01 and traced the boot pin to a pin on the chip and did the same on the dmax. Took a few tries but did work.

e54 are notorious for corrupting eeprom area for no reason. It needs special exit sequence after flash is done, so pcm reboots correctly, without overwriting the eeprom with some garbage data.

Can confirm In-Techs location on the second page of this thread is correct. Most apps I tried were not able to do a recovery flash though. I did get my test E54 going again, and was able to get PCMHammer working on E54 for write. I am not doing anything special and so far no bricks at shutdown. I think that may just be issues which the factory flash kernel, and the PCM Hammer one is fine. Hopefully I am correct about that and not speaking too soon It looks like E54 just needed the CPU Status register set a little different to what we have needed before. A write of the register with the right configuration, rather than an or. Without checking exactly why, I would say it likely had something to do with enabling supervisor mode or some of the other hardware access configuration. None the less the work that was already done was good with a write of 0x2700 to %sr instead of an just an ori with 0x700 to sr like works for all of the other targets so far at flash kernel init.
