Make it possible to update the (whole) bootloader on am335x robustly, i.e. so that a power failure or random OOM killing of the update process or other interruptions do not result in a bricked board.
The order the trial bits gets set is somewhat odd, but is clearly what happens, and somebody else trying to reverse engineer the ROM code has observed the same thing: See the TracingVectors.ods in https://github.com/sjgallagher2/am335xbootrom . v2: Add patch updating documentation, including a sketch of shell commands that could be used for the actual update procedure. v1: https://lore.kernel.org/u-boot/[email protected]/ Rasmus Villemoes (2): am335x: add support for loading u-boot from multiple offsets doc: am335x: document use of CONFIG_SPL_AM33XX_MMCSD_MULTIPLE arch/arm/mach-omap2/Kconfig | 37 ++++++++++++++ arch/arm/mach-omap2/boot-common.c | 31 ++++++++++++ doc/board/ti/am335x_evm.rst | 80 +++++++++++++++++++++++++++++++ 3 files changed, 148 insertions(+) -- 2.52.0
