How to enter flash mode

Installation

Notes

Uart

`/dev/ttyHS8` can be exposed on USB D+D- lines. It's configured in data mover mode by downstream kernel.

Mainline

Building

  • build u-boot.bin file. Follow u-boot docs installation section
  • build mainline kernel
    • clone sources
    • source /home/dzmitry/side/pmos/pmbootstrap/helpers/envkernel.sh
    • make defconfig
    • make
  • assemble initramfs
  • TODO TODO: assemble u-boot fit image:

    Installing

    This section is useless for now, because currently there's no way to tell if something is alive, when you boot from the flash. See next section.

    Booting kernel and getting console

    Is performed with kexec-similar stuff for now. See guide for that method. Remember, you should have a cable like Samsung_Galaxy_A5_2017_(samsung-a5y17lte)#Notes a5y17lte UART USB-debug cable schematic, and 1.8V compatible uart adapter

    TODO TODO: provide prebuilt twrp image to boot kernel, and instruction how to use that.
