Installation

Extract the toolchains to proper folder -- be careful that the tar ball use ./ as top level path, move it to a seperate folder or specify a target folder for the uncompressing.

mkdir csky-elfabiv2-tools-x86_64-minilibc-20210423
tar xvf csky-elfabiv2-tools-x86_64-minilibc-20210423.tar.gz  -C csky-elfabiv2-tools-x86_64-minilibc-20210423/

Then move it to somewhere, e.g. /opt/toolchains, set it read-only to normal users

cd /opt/toolchains/
sudo mv ~/Download/csky-elfabiv2-tools-x86_64-minilibc-20210423/ .
sudo chown -R root:root csky-elfabiv2-tools-x86_64-minilibc-20210423/

You don't need to add it to the system PATH variable.

Building

Checkout this project

git clone https://github.com/IOsetting/wm-sdk-w806.git

Run menuconfig, configurate the toolchains path

cd wm-sdk-w806
make menuconfig

In menuconfig, navigate to Toolchain Configuration, In the second line "the toolchain path", input the absolute path of the toolchains executables, e.g.

/opt/toolchains/csky-elfabiv2-tools-x86_64-minilibc-20210423/bin/

Leave other settings unchanged, save and exit menuconfig.

Then build the project

make

More Building Options

• UART0 printf() output
  In /include/arch/xt804/csi_config.h, option USE_UART0_PRINT controls whether use UART0 to send printf() output, it is turned on by default. Note: This feature will occupy UART0, if any other devices are going to communicate with UART0, please turn it off.
• Hands-free download
  In /include/arch/xt804/csi_config.h, option USE_UART0_AUTO_DL controls enable/disable automatic download, it is turned off by default. When it is enabled, download tool will reset the board automatically before the downloading. Option USE_UART0_PRINT should be enabled to make this work.

Download To Development Board

Connect the development board to PC, get the USB port name by commands dmesg, lsusb and ls /dev/tty*.

Run menuconfig to set the download port

cd wm-sdk-w806
make menuconfig

In menuconfig, navigate to Download Configuration

• Download port: Input the USB port name, e.g. ttyUSB0;
• Down rate: Input the UART baud rate, the higher rate the higher download speed. The availabe options are 115200, 460800, 921600, 1000000 and 2000000.

Then save and exit menuconfig, download the hex file to development board

make flash
