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:
- SMART-EVB for T-Head CPU E9xx Series
| res | description |
|---|---|
| ISA | RISCV |
| CPU | E906 |
| FREQ | 20MHz |
| SRAM | 768KB |
- SMART-EVB for E804/E804F/E804D
| res | description |
|---|---|
| ISA | C-SKY |
| CPU | E804 |
| FREQ | 20MHz |
| SRAM | 768KB |
Compile T-HEAD BSP
SMART-EVB BSP supports GCC compiler, the version information is:
- 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 |
