We have assembled an All-In-One SDK that includes SiRV-SDK Toolchain, and OpenOCD. You can download the SDK from given link below.
Extract the downloaded archive to the current working directory.
lrzuntar sirv-e-sdk.tar.lrz
You will need lrzip for the above command to work. Install it using the following command.
sudo apt-get install lrzip
We are going to Compile a GPIO demo that Blinks the Onboard LED on Tang Primer.
Use the following cammand to compile the Demo.
cd sirv-e-sdk
make software PROGRAM=demo_gpio BOARD=sirv-e203-lichee
We need to first setup proper permissions to access USB Debugger.
Add your username to plugdev group. Replace <username> with your present working system’s username.
sudo usermod -a -G plugdev <username>
Set udev rules to enable Tang Primer to be accessed by the plugdev group,
Execute the following command in terminal to create a new udev rules file.
sudo nano /etc/udev/rules.d/45-dt2232.rules
Copy the following code into the text editor and save it, as shown in the following image.
SUBSYSTEMS=="usb", ATTRS{idVendor}=="0403", ATTRS{idProduct}=="6010", \
GROUP="plugdev", \
MODE="0660"
Execute the following command in terminal to restart the udev service.
sudo service udev restart
Press ctrl+x to save the file
Connect Tang Primer with RV Debugger as shown below.
| Tang Primer | RV Debugger |
|---|---|
| U0_RX (Pin H13) | TX |
| U0_TX (Pin J13) | RX |
| E_TMS (Pin C9) | TMS |
| E_TDI (Pin B6) | TDI |
| E_TCK (Pin C5) | TCK |
| E_TDO (Pin A4) | TDO |
| GND (Pin G) | GND |
Pin locations on the Tang board can be found in Pinout Diagram.
Execute the following command in “sirv-e-sdk” folder to upload demo into the board.
make upload PROGRAM=demo_gpio BOARD=sirv-e203-lichee
OpenOCD provides us a nice way to debug our programs.
Run the OpenOCD GDB server with the following command and leave it running.
make run_openocd PROGRAM=demo_gpio BOARD=sirv-e203-lichee
In the other Terminal run the following command to debug your code using familiar GDB Debugger.
make run_gdb PROGRAM= demo_gpio BOARD=sirv-e203-lichee
