This SDK is for Kendryte K210 which contains FreeRTOS support.
Ported from Kendryte kendryte-freertos-sdk
Changes to make the SDK work better with MicroPython, but can be used as SDK for other applications to
You may want to edit lib/freertos/conf/FreeRTOSConfig.h to make some changes to better suit your needs.
Use the latest Kendryte GNU Toolchain v8.2.0-20190409.
To compile only the libraries, execute (no project given):
cd build
cmake ../ -DTOOLCHAIN=<path_to_kendryte-toolchain>/bin
make The following libraries will be created in build directory:
third_party/fatfs/libfatfs.a
third_party/lwip/liblwipcore.a
SDK/bsp/libbsp.a
SDK/drivers/libdrivers.a
SDK/hal/libhal.a
SDK/posix/libposix.a
SDK/freertos/libfreertos.a
To build the project, place your project source files in the directory src/<project_name> and execute:
cd build
cmake ../ -DPROJ=<project_name> -DTOOLCHAIN=<path_to_kendryte-toolchain>/bin
make Use -jN make option for faster build.
Change working directory to build directory.
Export your Kendryte toolchain directory path, for example
export CROSS_COMPILE=${PWD}/../../kendryte-toolchain/bin
Execute:
cmake ../ -DPROJ=uart_example -DTOOLCHAIN=${CROSS_COMPILE}
make -j8
Flash the created uart_example.bin to your board.
kflash.py is provided in the src directory.
Change working directory to src directory.
Execute:
./kflash.py -p /dev/ttyUSB0 -b 2000000 -t ../build/uart_example.bin
This version of kflash.py has terminal emulator included, with -t option it will be started after flashing.
- Drivers
- uarths: added -
uarths_baudrateglobal variable used byuarths_initfunction - uart: enable using external uart irq handler, added functions
uart_get_driver(handle_t file),uart_get_handle(void *driver) - i2c: some changes and new functions
- spi: many changes, some new functions, much improved slave support
- gpiohs: some changes for better interrupt handling
- gpio: added some missing functions
- timer: added some functions
- pwm: added some functions
- dmac:
dma_completion_isr, do not assert on wrong int status, but provide the interrupt status in global variable to be used by caller function
- uarths: added -
- syslog: various changes
- print log time in micro seconds
- make syslog level configurable during run time
- make syslog colors configurable during run time
- add syslog mutex
- enable filtering of non-printable characters
- FreeRTOS
tasks:- lot of changes for better multiprocessor support
- some useful functions added or enabled
- all notification functions uses 64-bit values
- FreeRTOS
heap_4: added functionspvPortRealloc&pvPortCalloc - filesystem: added setting file time from external function (
get_fattime(void)function), enabledf_mkfs()function, default code page set to 850 - lwip: added SHA256, enabled PPP support, enabled IGMP, thread priority set to 12
- SNTP: added function
set_rtc_time_from_seconds(time_t seconds)to set RTC, enabled support for DNS names
- SNTP: added function
- added reading 64-bit CSR, function:
read_csr64(reg) - other small changes for better functionality and no compiler warnings
