Other terminal emulators (screen, minicom) default to sending CR when
ENTER is pressed on the keyboard. Make behavior of idf_monitor
consistent with them.
Between 3.1.0 and 3.3.0, pyserial had thread cancellation implemented
using a select, which blocked on the stdin and an auxiliary pipe. When
thread had to be cancelled, a byte would be sent into the pipe,
unblocking stdin.
Unfortunately, this method suffers from a problem with using select on
a StreamReader (which represents the decoder wrapped around stdin).
In some cases, when the TTY sends an escape sequence in response to
an escape sequence received from serial, this escape sequence will not
be read from stdin until some key is pressed.
In https://github.com/pyserial/pyserial/commit/cab3dab, this method
was replaced with an TIOCSTI ioctl. This change makes sure we use the
new cancellation method even if the script is running with older
pyserial.
Previously VFS driver for UART could only use simple non-blocking
functions to read from and write to the UART. UART driver provides more
complex blocking and interrupt-driven functions, which can be used
instead.
This commit adds optional support for using UART driver's functions.
Also added is a more flexible mechanism for configuring newline
conversion rules on input and output.
This commit also fixes a bug that all UARTs shared one static variable
used as a character buffer in newline conversion code. This variable is
changed to be per-UART.
* Disables 3DES, Camellia, Blowfish, RC4, RIPEMD160, SSLv3, TLS-PSK modes, DTLS by default
* Saves about 40KB from the default TLS client code size
* Defaults no longer get "Bad" howsmyssl.com rating (no more vulnerable 3DES)
(ping https://github.com/espressif/arduino-esp32/issues/575 )
* Allows up to another 20-30KB code size to be trimmed without security
implications if using DER formatted certificates, RSA ciphersuites only,
etc.
* Can save up to another 8KB by setting the TLS Role to Server or Client only.
1. Hello World application shows no footprint difference before and
after this change
2. examples/ethernet/ethernet application compiles properly (can't
test with my board)
Remove wifi config option
Remove Wi-Fi enable/disable option from Kconfig. This can be detected by the presence of esp_wifi_init() function in the application. Minimum footprint impact after the change.
See merge request !1098
This is no longer required since the functions automatically get
pulled in based on the usage. A quick summary of footprint
comparisions before and after these set of patches is shown below:
Hello-World: (simplified for readability)
old Total image size:~ 104902 bytes (.bin may be padded larger)
old Total image size:~ 105254 bytes (.bin may be padded larger)
Per-archive contributions to ELF file:
Archive File DRAM .data & .bss IRAM Flash code & rodata Total
old libesp32.a 1973 177 4445 3939 2267 12801
new libesp32.a 1973 185 4473 3939 2267 12837
new libnvs_flash.a 0 92 0 274 8 374
new libstdc++.a 0 0 0 24 0 24
For some reason, nvs_flash.a (~400bytes) gets pulled in (particularly
the nvs_flash_init() function).
Power-Save: (simplified for readability)
old Total image size:~ 421347 bytes (.bin may be padded larger)
old Total image size:~ 421235 bytes (.bin may be padded larger)
old libtcpip_adapter.a 0 81 0 1947 115 2143
new libtcpip_adapter.a 0 69 0 1897 115 2081
The size actually shrinks a bit, since the AP interface function
doesn't get pulled in.
Since only the used interface's start function gets called, it pulls
in only the functions that are required in the current application,
thereby saving footprint.
Restart being a lower-layer system-level function, needn't depend on
the higher level Wi-Fi libraries.
This also enables us to get rid of one more WIFI_ENABLED ifdef check
The address field should be placed at the highest bits of address and slv_wr_status registers. Instead of breaking the address into two parts and fill in each register, move the address to the highest bits and write to the registers respectively.
Breaking change: if you fill-in the SPI address filed in a previous version in some way and it works correctly, you still have to rewrite the address, in a more intuitive way.
force rxlength=length and mosi=1 and inlink.start=1 on in full-duplex mode.
set rxlength > length is forbidden in full-duplex mode.
