Partition/SPI/OTA docs & OTA new functionality
* Update partition, SPI flash & OTA docs to reflect functionality changes
* Refactor OTA implementation to perform checks mentioned in API doc
* Add new functions to OTA API: esp_ota_get_running_partition() & esp_ota_get_next_update_partition() functions
* Add spi_flash_cache2phys() & spi_flash_phys2cache() functions to support esp_ota_get_running_partition()
See merge request !513
1. Add disable PHY and RF when WiFi and BT are both disabled(including call sniffer disable API).
2. Do not init PHY and RF when cpu start. Init PHY and RF when call Wifi or BT start APIs(including sniffer enable API).
3. Add a temporary lib: librtc_clk.a and will delete it when CPU frequency switching function is done.
4. Add an function to get OS tick rate.
5. Do not put the whole pp.a in iram0, only put lmac.o, ieee80211_misc.o, ets_time.o and wdev.o in iram0.
Docs: Document flash encryption disable steps, clean up flash encryption & secure boot docs
Generate clean up of flash encryption & secure boot docs
Including steps for disabling flash encryption (for people who accidentally enable it).
See merge request !500
Also add steps to disable flash encryption, as some people seem to
accidentally enable it.
Explicitly mark the flash encryption and secure boot as "READ DOCS
FIRST" in menuconfig.
build system: add IDF_VER environment variable and preprocessor define
This adds an `IDF_VER` preprocessor define which is obtained from `git describe`.
Looks like `v1.0-275-g0efaa4f` for non-release version or `v2.0` for a tagged (release) version.
See merge request !403
Enable bootloader entropy source for RNG
Enables an entropy source when bootloader starts up, which both seeds the RNG for use before WiFi/BT stack is enabled and provides an adequate RNG for secure boot & flash encryption key generation.
A prerequisite was enabling 80MHz operation, so the CPU is now set to 80MHz as soon as second stage bootloader starts running.
See merge request !363
Modify bootloader dram_seg from address 0x3ffc0000 to 0x3fff0000, len from
0x20000 to 0x10000. Please be notified that this is just a workaround for
fixing app data overwrite bootloader data issue!
Flash encryption support
Flash encryption support in build system, tooling
To come in future MR:
* On-device key generation on first boot (for production devices), need to finalise testing of bootloader entropy seeding.
* spi_flash_encrypted_write to support non-32-byte block writes (at least optionally.)
* I think a lot of the bootloader_support component can possibly be rolled into "spiflash" and other components, to use a common API.
See merge request !240
This change adds a set of menuconfig options to set custom UART#, baud rate, and pins, for console output.
Setting happens in bootloader startup code for PRO CPU, and in application startup code for APP CPU.
Ref. TW8146
* App access functions are all flash encryption-aware
* Documentation for flash encryption
* Partition read/write is flash aware
* New encrypted write function
rename nvs host test folder, modify .gitlab-ci.yml
remove unit-test-app build
re-format unit test files
remove extra newlines in project.mk
some refactoring for unit test part in project.mk
add build files of unit-test-app in gitignore
add README.md for unit test app
correct headings in README.md
remove files and make minor tweaks in unit test app
update .gitlab-ci.yml to use unit test app
delete unused lines in component_wrapper.mk
delete periph_i2s.h and lcd test
add text floating point in components/esp32/test/Kconfig
correct idf test build paths in .gitlab-ci.yml
New makefile component_wrapper.mk allows some variables to be set
before component.mk is evaluated. This properly fixes problems with
sdkconfig being hard to access in all phases of the build.
Including component_common.mk is no longer necessary and will print a
deprecation warning for components which use it.
