OTA Bootloader (rboot) source module and support files.
|
||||
|
||||
Can be used to build an esp-open-rtos compatible rboot bootloader, for use when OTA=1.
|
||||
|
||||
It is also possible to use the upstream rboot verbatim, but *ensure that the `RBOOT_BIG_FLASH` option is enabled or images in slots other than 0 won't work correctly.
|
||||
|
||||
rboot is an open source bootloader by Richard Burton:
|
||||
https://github.com/raburton/rboot
|
||||
|
||||
See the contents of the 'rboot' directory for more information.
|
||||
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.
