@knc1 Could you recommend a firmware we could try first? PW4-12.2.2? |

Finally, I managed to configure the ghidra server. The active repository is pw4-5.12.2. It may make sense to preserve the original firmware paths. Later I will think about backups, migrations, etc. For anyone interested you can PM me (and later other people who will be able to add new users to the repository) for credentials and other access info.

Coming back to the original topic. Does anybody aware of what kind of binaries and for what kind of architecture are files bios.bin/s-bios.bin/u-boot.bin inside imx6sll_rex/ directory inside update_xxx.bin?

Bare metal.
If asking how they are packaged ... It might be something Android related if not u-image, and the u-boot file should always be u-image. |

Thanks, that helps to understand what is u-boot.bin
However, it's still unclear (1) for what type of a chip the rest of binaries are, (2) how to disassemble them. And (3) what is the process of booting (the big picture). I have some experience with PIC micro-controllers and soldering-related stuff. So, I hope, I'll be able to tell more after tools for disassembling kindle and serial/usb board arrive. Update 1: Interestingly, here is what binwalk says about bios.bin (original image): Last edited by pavel-s; 11-19-2019 at 10:39 PM. Reason: add binwalk output |

Slightly clickbait-ish. Last I checked, lab126 used much older uboot builds, and heavily customized ones at that . That said, it'd take someone much more familiar with that to make a decisive announcement .
