This is a workaround for the inconsistent device naming pattern
implemented in the device driver for Silicon Labs CP2102 USB to UART
Bridge Controller. When there are multiple devices installed on one
computer, the second and subsequent devices are given a numeric suffix
that increments every time one of the devices is plugged in. Thus,
unplugging and reinserting a cable causes the device name to change.
The workaround is to use the device USB location identifier as an
alternative consistent handle for the device, assuming that the cable
is plugged into the same jack each time. This workaround does not
interfere with using the normal device name as the handle for cases
where only one device is used or when the inconsistent naming is not a
problem.
Fix warnings where undefined vars are used.
Make Kconfig emit "FOO=" for unset bool options
To ensure make variables are always defined, even if empty.
When writing auto.conf, include symbols disabled by dependency to make sure all make variables are always defined.
Fixesespressif/esp-idf#137
Cherry-picked from https://github.com/espressif/esp-idf/pull/138
Makes app image booting more reliable (256-bit rather than 8-bit verification.)
Some measurements, time to boot a 655KB app.bin file and run to app_main() execution.
(All for rev 1 silicon, ie no 340ms spurious WDT delay.)
80MHz QIO mode:
before = 300ms
after = 140ms
40MHz DIO mode:
before = 712ms
after = 577ms
40MHz DIO mode, secure boot enabled
before = 1380ms
after = 934ms
(Secure boot involves two ECC signature verifications (partition table, app) that take approx 300ms each with 80MHz CPU.)
For config-only components, component.mk should now contain "COMPONENT_CONFIG_ONLY := 1"
Also refactored some of the generation of linker paths, library list. This required cleaning up the way the bootloader
project works, it's now mostly independent from the parent.
Fixes issue with GPIO 0 being enabled as an output on ESP32D2WD (or when setting SPI pins in efuse)
and not using Quad-I/O modes.
Ref: https://esp32.com/viewtopic.php?f=2&t=2205
* "make monitor" not passed the configured baud rate
Closes#436https://github.com/espressif/esp-idf/issues/436
* Pass toolchain prefix from sdkconfig into monitor tool
* Allow setting EOL in idf_monitor.py, use CRLF by default
* Detect if /dev/tty.X is used on macOS, warn and replace with /dev/cu.X
* If a build fails or gdb exits, ignore Ctrl-T (allowing Ctrl-T Ctrl-A/F to be same key sequence everywhere)
* Add a note about winpty on Windows
Ref 02fdf8271d (commitcomment-21369196)
Originally marked "Reset with ESP32R0 Windows workaround", but proven to be
necessary on some other platforms as well. This is now integrated into the
default esptool.py reset behaviour.
Closes#305https://github.com/espressif/esp-idf/issues/305
* New "espefuse.py set_flash_voltage" command to easily set a fix
VDD_SDIO regulator voltage (1.8V, 3.3V or disabled).
* Fixes bugs when flashing files with non-4-byte aligned lengths
(doesn't effect esp-idf image files)
* README improvements
* App access functions are all flash encryption-aware
* Documentation for flash encryption
* Partition read/write is flash aware
* New encrypted write function
Required at project level because some components use header files in
other components' submodules, and one component with a
submodule (esptool.py) doesn't have or need a component.mk.
