Greetings,
I have the new model of Toyota multimedia with my car came from Japan and its locked, and I'm willing to unlock it with an ERC code, I would pay for it to Toyota dealers or smh, but the cars coming to us is used right-handed cars from Japan, so the dealer is not an option. Being an programmer and electronic engineer by myself I tried to figure out how multimedia works, it has a microSD card slot where microSD has a loading file (400mb), I have decompiled it, and it turned out it has Linux ext2 filesystem, the funny thing that its lack of u-boot image or kernel image, seems like it is on the emmc flash and when the card is inside it starting to look for Linux on the card (w/o card the multimedia won't even start). As I understand the Linux loading order it should search for inittab file right? Also, it is a lot of .class java and .png files outside of the ext2 filesystem, so I'm struggling with the basics, how embedded Linux works? The loading order should be U-Boot->Kernel U-image->Inittab, right? And how it is using the .class files outside of the ext2 Linux filesystem? Of the cause, the final goal is to find an ERC calculation principle, but I want figure out how Linux works from the start and where the user files can be located. Are there any embedded Linux users?
