2021-10-25mimxrt/dma_channel: Fix the DMA channel management.robert-hh
The MIMXRT1011 has only 16 channels, so size the channel list accordingly.
2021-10-25mimxrt/hal: Remove duplicate definitions from flexspi_hyper_flash.h.robert-hh
2021-10-25mimxrt/boards: Fix the D14/D15 pin assignment of MIMXRT1050/60/64_EVK.robert-hh
There are several PCB layouts in the market under the same name.
2021-10-25mimxrt/modmachine: Implement machine.WDT() and machine.reset_cause().robert-hh
The API follows that of rp2, stm32, esp32, and the docs. wdt=machine.WDT(0, timeout) Timeout is given in ms. The valid range is 500 to 128000 (128 seconds) with 500 ms granularity. Values outside of that range will be silently aligned. wdt.feed() Resets the watchdog timer (feeding). wdt.timeout_ms(value) Sets a new timeout and feeds the watchdog. This is a new, preliminary method which is not yet documented. reset_cause = machine.reset_cause() Values returned: 1 Power On reset 3 Watchdog reset 5 Software reset: state after calling machine.reset() More elaborate API functions are supported by the MCU, like an interrupt called a certain time after feeding. But for port cosistency that is not implemented.
2021-10-25mimxrt/eth: Add LAN support and integrate the network module.robert-hh
This commit implements 10/100 Mbit Ethernet support in the mimxrt port. The following boards are configured without ETH network: - MIMXRT1010_EVK - Teensy 4.0 The following boards are configured with ETH network: - MIMXRT1020_EVK - MIMXRT1050_EVK - MIMXRT1060_EVK - MIMXRT1064_EVK - Teensy 4.1 Ethernet support tested with TEENSY 4.1, MIMRTX1020_EVK and MIMXRT1050_EVK. Build tested with Teensy 4.0 and MIMXRT1010_EVK to be still working. Compiles and builds properly for MIMXRT1060_EVK and MIMXRT1064_EVK, but not tested lacking suitable boards. Tested functions are: - ping works bothway - simple UDP transfer works bothway - ntptime works - the ftp server works - secure socker works - telnet and webrepl works The MAC address is 0x02 plus 5 bytes from the manifacturing info field, which can be considered as unique per device. Some boards do not wire the RESET and INT pin of the PHY transceiver. For operation, these are not required. If they are defined, they will be used.
2021-10-22mimxrt/sdram: Add SDRAM support.Philipp Ebensberger
Adds support for SDRAM via `SEMC` peripheral. SDRAM support can be enabled in the mpconfigboard.mk file by setting `MICROPY_HW_SDRAM_AVAIL` to `1` and poviding the size of the RAM via `MICROPY_HW_FLASH_SIZE`. When SDRAM support is enabled the whole SDRAM is currently used used for MicroPython heap. Signed-off-by: Philipp Ebensberger

2021-10-16esp32: Enable optimisations and move code to iRAM to boost performance.Damien George
This commit enables some significant optimisations for esp32: - move the VM to iRAM - move hot parts of the runtime to iRAM (map lookup, load global/name, mp_obj_get_type) - enable MICROPY_OPT_LOAD_ATTR_FAST_PATH - enable MICROPY_OPT_MAP_LOOKUP_CACHE - disable assertions - change from -Os to -O2 for compilation It's hard to measure performance on esp32 due to external flash and hardware caching. But this set of changes improves performance compared to master by (on a TinyPICO with the GENERIC build, using IDF 4.2.2, running at 160MHz): diff of scores (higher is better) N=100 M=100 esp32-master -> esp32-perf diff diff% (error%) bm_chaos.py 71.28 -> 268.08 : +196.80 = +276.094% (+/-0.04%) bm_fannkuch.py 44.10 -> 69.31 : +25.21 = +57.166% (+/-0.01%) bm_fft.py 1385.27 -> 2538.23 : +1152.96 = +83.230% (+/-0.01%) bm_float.py 1060.94 -> 3900.62 : +2839.68 = +267.657% (+/-0.03%) bm_hexiom.py 10.90 -> 32.79 : +21.89 = +200.826% (+/-0.02%) bm_nqueens.py 1000.83 -> 2372.87 : +1372.04 = +137.090% (+/-0.01%) bm_pidigits.py 288.13 -> 664.40 : +376.27 = +130.590% (+/-0.46%) misc_aes.py 102.45 -> 345.69 : +243.24 = +237.423% (+/-0.01%) misc_mandel.py 1016.58 -> 2121.92 : +1105.34 = +108.731% (+/-0.01%) misc_pystone.py 632.91 -> 1801.87 : +1168.96 = +184.696% (+/-0.08%) misc_raytrace.py 76.66 -> 281.78 : +205.12 = +267.571% (+/-0.05%) viper_call0.py 210.63 -> 273.17 : +62.54 = +29.692% (+/-0.01%) viper_call1a.py 208.45 -> 269.51 : +61.06 = +29.292% (+/-0.00%) viper_call1b.py 185.44 -> 228.25 : +42.81 = +23.086% (+/-0.01%) viper_call1c.py 185.86 -> 228.90 : +43.04 = +23.157% (+/-0.01%) viper_call2a.py 207.10 -> 267.25 : +60.15 = +29.044% (+/-0.00%) viper_call2b.py 173.76 -> 209.42 : +35.66 = +20.523% (+/-0.00%) Five tests have more than 3x speed up (200%+). The performance of the tests bm_fft, bm_pidigits and misc_aes now scale with CPU frequency (eg changing frequency to 240MHz boosts the performance of these by 50%), which means they are no longer influenced by timing of external flash access. (The viper_call* tests did previously scale with CPU frequency, and they still do.) Turning off assertions reduces code size by about 80k, and going from -Os to -O2 costs about 100k, so the net change in code size (for the GENERIC board) is about +20k. If a board wants to enable assertions, or use -Os instead of -O2, that's still possible by overriding the sdkconfig parameters. Signed-off-by: Damien George <damien@micropython.org>

2021-10-15stm32/sdram: Enforce gcc opt, and use volatile and DSB in sdram_test.iabdalkader
Ensures consistent behaviour and resolves the D-Cache bug (the "exhaustive" argument being lost due to cache being turned off) when O0 is used. The changes in this commit are: - Change -O0 to -Os because "gcc is considered broken at -O0" according to https://github.com/ARM-software/CMSIS_5/issues/620#issuecomment-550235656 - Use volatile for mem_base so the compiler doesn't optimise away reads or writes to the SDRAM, which is being tested. - Use DSB to prevent any other compiler optimisations that would change the testing logic. - Use alternating pattern/antipattern in exhaustive test to catch more hardware/configuration errors. Implementation adapted by @andrewleech, taken directly from investigation by @iabdalkader and @dpgeorge. See #7841 and #7869 for further discussion.

2021-09-24esp32/main: Add option for a board to hook code into startup sequence.Damien George
To do this the board must define MICROPY_BOARD_STARTUP, set MICROPY_SOURCE_BOARD then define the new start-up code. For example, in mpconfigboard.h: #define MICROPY_BOARD_STARTUP board_startup void board_startup(void); in mpconfigboard.cmake: set(MICROPY_SOURCE_BOARD ${MICROPY_BOARD_DIR}/board.c ) and in a new board.c file in the board directory: #include "py/mpconfig.h" void board_startup(void) { boardctrl_startup(); // extra custom startup } This follows stm32's boardctrl facilities.

2021-09-24esp32/mpthreadport: Fix TCB cleanup function so thread_mutex is ready.leo chung
Because vPortCleanUpTCB is called by the FreeRTOS idle task, and it checks thread, but didn't check the thread_mutex. And if thread is not NULL, but thread_mutex not ready then it will crash with an error when calling mp_thread_mutex_lock(&thread_mutex, 1). As suggested by @dpgeorge, move the thread = &thread_entry0 line to the end of mp_thread_init(). Signed-off-by: leo chung <gewalalb@gmail.com>

2021-09-21docs/esp32: Explain ESP32 PWM modes, timers, and channels.IhorNehrutsa
2021-09-21esp32/machine_pwm: Add support for all PWM timers and channels.IhorNehrutsa
This commit allows using all the available PWM timers (up to 8) and channels (up to 16), without affecting the PWM API. If a new frequency is set, first it checks if another timer is using the same frequency. If yes, then it uses this timer, otherwise, it creates a new one. If all timers are used, the user should set an already used frequency, or de-init a channel. This work is based on #6276 and #3608.

2021-09-19stm32/boards: Add OLIMEX H407 board definition.Chris Fiege
This change adds the OLIMEX H407 support to the STM32 port. The H407 (https://www.olimex.com/Products/ARM/ST/STM32-H407/) is simliar to the already existing E407 (https://www.olimex.com/Products/ARM/ST/STM32-E407) but does not support Ethernet and has a full-size USB-A port instead of a Mini-USB socket. Both boards use the STM32F407ZGT6 CPU. This port is basically a copy of the E407 but with changed pinmux: * Removed Ethernet pin definition * Removed UART1 (pins are used for other functions) * Removed UART3 flow control pins (pins are used for other functions) * Removed SD-Card detect pin (since it is not connected on the H407) A REPL on UART3 is connected to the U3BOOT-header, a 3-pin header with RX, TX and GND that is intended for the serial terminal. Tested: * Micro-SD Card is detected when inserted on RESET * REPL on UART3 works * Serial port on the mini USB socket Signed-off-by: Chris Fiege <cfi@pengutronix.de>
