Hacking the GM HMI 2.5 module.

If someone want to try... Calibrations for HMI 2.5 84099718/84028485 from Buick Encore 2019.

I dont know if are compatibles with europeans HMIs 2.5 and others HMI numbers.

has an announce on google. you can search it using the vin. KL4CJCSM9KB891239

a few days ago, tested anothers cals from Chevy, Cadillac in a hmi 2.0 and works...

HMI 84099718.zip

well, works in a 234 15900 hmi 2.5.

Now i cant go back to Opel theme. LOL via sps, software not available for this hmi

Yeah, same error for me for SPS2.. I guess it does not like seeing "incorrect" CALs than it was expecting.

someone has archieved the uboot mode in the hmi 2.5? im trying but...

the system boots normaly

I was also not able to get in U-Boot, i just changed the settings in the Partition like HMI_Guy has described.

But I didn't get it SSH to work because the ASIX AX88179 driver is not installed and not able to installed.

still working.

Is it possible to connect using serial console to Instrument cluster UHS?

i dont think so possible. the HMI is a linux system based and have the console serial port. but the UHS.. i dont know.

interesting stuff. Do you know what that install and recorder icon is used for? 

I've been doing some research, and the Recorder button is for, as the name suggests, to record video from the K157 module. K157 is the 360 vision module (RPO UVH) and all the cameras in the car are connected to this module. Front, sides and rear. Example vin: W0VZT6GF1J1168520 In the TIS, there is detailed information about the Recorder function

Hi, someone knows if the SHOP app in the hmi 2.5 still working in USA vehicles?

In EU vehiches the shop goes to
vehicle.api.eur.onstar.com:443 > this host is dead

in USA veiches:
vehicle.api.gm.com:443

Yes, it's a known link.
But these files are just Open-source system firmware (kernel, drivers, runtimes etc.).
GM receive that base image from Bosch, and build their HMI system on top of that.

if you have access to SPS, you can perform a usb download the HMI firmware. around 2,7Gb.

Sorry, but what would SPS be?

Hello, good times everyone.

 

I'm in the process of finding out about the HMI module. I already know the SD solder points, I have a backup SD with the software in version SW.15.2B033. The issue is that same version is not accepted in other frames.

 

Being Linux files their reading by me is vague.

I believe I'm close to being able to adapt the sd in place of the memory without much difficulty. 

Can you give any tips, is it possible to use the same files in another HMI, is your data only in memory?

Sorry about my English.

Nice work on adapting the SD adapter.

Changing only the data from the EMMC is not going to work. All the system checksums are in the EMMC, but it checks against the NOR GL512. So you have to change the data from both. Calibration data is stored in the NOR. My advice is change the data in both the EMMC and NOR. 

Dump emmc data from the new hmi product, and then raise the screen. However, a reboot occurs after 1 minute and 22 seconds.

Is it a problem to transform emmc data?

in a HMI 2.0 I have the same problem with non opel calibrations. it reboots randomly. but with opel calibrations it works normally.

Hi guys.
Which setup do I need to run HMI with screen on the bench? I have HMI 2.5, escalade lcd and radio module. What do I need to do to turn on the screen?
Battery voltage applied to all modules, MOST looped, LIN5 and LIN10 connected to display module, communication enable pulled up to supply voltage, but screen still dark.

Thank you in advance.

Radio (EU Silverbox or US Densoten) HMI, speedometer (UDD or UHS) and close the most bus betwen all units in ring. need to connect the blue cable from HMI to Display (LVDS video signal) and most control from radio to all units in the most bus

IPC? For what? Need I connect BCM?
