u-boot.git/cmd/ab_select.c, branch v2024.01 Unnamed repository; edit this file 'description' to name the repository. android_ab: Add option to skip decrementing tries 2023-07-17T19:39:55+00:00 Joshua Watt jpewhacker@gmail.com 2023-06-23T22:05:48+00:00 22cdb3f0f174e926071975cdc5157aa6526b67a7 It is is sometimes desired to be able to skip decrementing the number of tries remaining in an Android A/B boot, and instead just check which slot will be tried later. This can commonly be be the case for platforms that want to A/B u-boot itself, but are required to boot from a FAT MBR partition. In these cases, u-boot must do an early check that the MBR points to the correct A/B boot partition, and if not rewrite the MBR to point to the correct one and reboot. Decrementing the try count in this case is not desired because it means that each u-boot might constantly ping-pong overwriting the MBR and rebooting until all the retries are used up.

cmd: Add 'ab_select' command 2019-07-24T17:16:29+00:00 Ruslan Trofymenko ruslan.trofymenko@linaro.org 2019-07-05T12:37:33+00:00 17030c7c4c99c09f439641628734dfc5840da3ff For A/B system update support the Android boot process requires to send 'androidboot.slot_suffix' parameter as a command line argument. This patch implementes 'ab_select' command which allows us to obtain current slot by processing the A/B metadata. The patch was extracted from commit [1] with one modification: the separator for specifying the name of metadata partition was changed from ';' to '#', because ';' is used for commands separation.
