Unbricking a CID #79

Is it possible Spansion is corrupt? Can someone send me a working dump of Spansion and the firmware that goes along with it? |
|
did you tru to view update log? |
I haven't checked the log files, do they have any info in them that edit: cid-updater.log is empty. |
|
Can you show what you have on |
I'll attach a serial log since I get disconnected from updater after it reboots gateway to update it. I sent it |
|
Probably unable to do the hwacq phase, is there a CAN module missing ? You probably can get the log from the gw Connect to gw and do |
|
Haven't had a chance yet to go out to the car but uh, does the dimmable rearview mirror use CAN? And would that being disconnected cause an updater error? I've been running a lot of these installs on the bench with an IC connected, but it wasn't succeeding when installed in the car either. Edit: Just realized it might be my airbag module it's unhappy about, I hadn't reinstalled it because I wanted to get this firmware issue sorted out, but might be preventing me from installing firmware. I'll get the mirror, airbags, and SRS module in before I try another firmware install. |

HWIDACQ.LOG and UDSDEBUG.LOG would 100% tell you where it fails. Also, if rooted, grep gwmon on syslog you would see. |
|
I wonder if you solved the problem? From the log, it seems that your high voltage connector is not off, and some other hardware is not communicating, possibly because there is no high voltage. |
|
Can I have a copy of your emmc dump? I also had some trouble with my car. I would like to study it and not use it for other purposes. In exchange, I can share some other versions of offline firmware with you. |
That log was taken with the MCU on the bench, but I did record another log with it in the car. With Jeankalud's help we figured out that the disconnected radar module was preventing the hwidacq stage from completing, so the update would never stage. I'll go ahead and post updated logs tomorrow. I still have a no-boot situation, but I'll have to do some more troubleshooting when I have time (hopefully starting tomorrow.) |

I was attempting (and may continue to) get U-boot and the open source kernel built to make modding and debugging easier. That should made it possible to obtain permanent root on even the latest firmware, and have complete control over the OS. For now, I just want to get my car working. If I were able to get access to Spansion flash, this would probably be a whole lot easier. |
Sure, contact me on Discord @ Synthax#0001 I have various dumps I can share and plenty of research I can discuss if you'd like. |

hello, friends. I'm wondering about the u-boot loader, has anyone managed to make it work? if anyone needs dumps, write, I have a lot of dumps and firmware for tegra and intel. |
Ok,I added you. |
I would like a emmc dump. My email is [email protected]. I would like to look study it. |
I have a partially working U-boot, it can't access the onboard eMMC or the NOR but is able to access the maps SD or the rear USB ports for loading a kernel (or the kernel can be loaded via serial) |
I'd be interested in those dumps. |
I've been trying for a while now to pin down why I can't get a single Tegra card to boot properly. I've tried to DD whole disk images to them from working cards, or just partitions 3/4, that were on the same firmware version as the bricked card. I've tried leaving 3/4 blank, or just copying over the contents of /var/etc/. I've tried upgrading or downgrading from CID updater, both will successfully stage and swap updater to the version I'm trying to install. Firmware seems to install on the IC, as it'll still boot and display just fine when installed in the car.
gostagedseems to fail every time, even with both staged_update: yes and gateway_needs_update: yes. Maps SD is inserted, same with gateway's card. Really don't understand why nothing I do will get these to stop booting to CID-recovery.The text was updated successfully, but these errors were encountered:
