OTA Bootloader (rboot) source module and support files.
rboot is an open source bootloader by Richard Burton: https://github.com/raburton/rboot
Wrapper rboot4lcm to complement homeaccessorykid/life-cycle-manager
The objective of this repo is to make rboot recognize multiple power reboots in short time. If detected, either the user code or the lcm ota-main sector will be launched. The amount of power cycles will be conveyed to the booted code. Values 1-4 are for the normal user code.
Ota-main will be able to erase bad settings. See LCM for more details.
This provides a fallback at all times to recover from bad user code or to change the user repository.
Most of the actual functionality will be made in the module rboot
To make rboot4lcm use
make clean all
To collect count in YOUR app, use this sample
#include <rboot-api.h>
int count=0;
rboot_rtc_data rtc;
if (rboot_get_rtc_data(&rtc)) count=rtc.temp_rom;
Can be used to build an esp-open-rtos compatible rboot bootloader. Run 'make bootloader' in this directory to compile a new bootloader.
Compiling a new bootloader is optional, there's a prebuilt one in the "firmware_prebuilt" directory that will be used if no new bootloader was compiled.
It is also possible to use rboot from upstream verbatim, but *ensure that the RBOOT_BIG_FLASH option is enabled or images in slots other than 0 won't work correctly.
See the contents of the 'rboot' directory for more information on rboot.
