Board Support Package For SparkFun RED-V RedBoard
Introduction
This board support package (BSP) supports SparkFun RED-V RedBoard. It is based on SparkFun Freedom-E-SDK and uses xPack GNU RISC-V Embedded GCC Version 8.3.0-2020.04.1 compiler tool chain for generating required binaries. Link: https://xpack.github.io/riscv-none-embed-gcc
Getting Started
· Install USB FTDI drivers from manufacturers web site.
· Create model and build to generate required binary.
· Refer below for programming and debugging support.

Programmer
CASP supports Programmer0 (via cmd.exe) for uploading generated binary file to the board flash memory. For this to work, user has to enter the USB storage device drive letter that the RedBoard creates (whenever it is connected to the host computer) in CASP Setup Simulation Parameters.> Target HW > General > Target Hardware Programmer Port parameter.
On Windows platforms: Just type the drive letter (example ‘E’) in the Programmer Port parameter mentioned above.
On Linux platforms: Type complete path of the drive along with the current user name (Example ‘/media/sample_user/HiFive’) in the Programmer Port parameter mentioned above.
Debugging
Debugging is supported over USB serial.
Known Issues & Limitations
- This BSP is presently work in progress.
- Very often UART not working at 115200 bps.
- Serial not working when other blocks are enabled
