# T-HEAD SMART-EVB Introduction
SMART-EVB is a development board provided by T-HEAD, based on FPGA to provide implementation, integrating T-HEAD's RISC-V CPU (eg. E902/E906/C906) and C-SKY CPU (eg. E805/E804/E803/E802 ), integrates basic peripheral resources such as GPIO/TIMER/UART/RAM.

## The main resources on board are as follows:

1. SMART-EVB for T-Head CPU E9xx Series

# Compile T-HEAD BSP
SMART-EVB BSP supports GCC compiler, the version information is:
1. SMART-EVB for E906/7/F/D/P

| IDE/Compiler| version|
| - | - |
| GCC | gcc version 8.4.0 (C-SKY RISCV Tools V1.9.6 B20200616) |
2. select cpu in rtconfig.py
3. scons -c; scons
