|
|
|
|
## 软件列表
|
|
|
|
* eclipse
|
|
* riscv toolchain
|
|
* riscv openocd
|

|
|
|
|
## riscv openocd
|
|
|
|
签出代码```git clone https://github.com/riscv-mcu/riscv-openocd```
|
|
|
|
编译
|
|
```
|
|
./configure --enable-cmsis-dap --enable-ftdi --prefix=安装目录路径
|
|
|
|
make
|
|
|
|
make install
|
|
```
|
|
|
|
|
|
## 配置eclipse
|

|
|
|
|
|
|
|
|
配置toolchain路径
|
|
|
|
|
|
|
|
|
|
配置openocd路径
|
|
|
|
|
|
|
|
|
|
##调试设置
|
|
|
|
添加如下两行
|
|
|
|
```
|
|
set arch riscv:rv32
|
|
set remotetimeout 250
|
|
```
|
|
|
|
|
|
|
|
|
|
## 如果用gd-link调试
|
|
|
|
配置文件
|
|
|
|
```
|
|

|
|
|
|
|
|
|

|
|
|
|

|
|
|
|

|
|
|
|
set _CHIPNAME riscv
|
|

|
|
|
|
|
|
# Work-area is a space in RAM used for flash programming
|
|
if { [info exists WORKAREASIZE] } {
|
|
set _WORKAREASIZE $WORKAREASIZE
|
|
} else {
|
|
set _WORKAREASIZE 0x5000
|
|
}
|
|
|
|
# Allow overriding the Flash bank size
|
|
if { [info exists FLASH_SIZE] } {
|
|
set _FLASH_SIZE $FLASH_SIZE
|
|
} else {
|
|

|
|
set _FLASH_SIZE 0
|
|
}
|
|
|
|
# flash size will be probed
|
|
set _FLASHNAME $_CHIPNAME.flash
|
|
|
|

|
|
riscv set_reset_timeout_sec 1
|
|
