## install xilinx
|
|
|
|
|
|
|
|
|
|
|
|
1. 下载vivado安装文件
|
|
|
|
|
|
2. 下载vivado lisence
|
|
|
|
|
|
3. 解压vivado的安装文件，sudo执行xsetup开始安装
|
|
|
|
|
|
4. 安装vivado之后，安装 Hardware Server
|
|
|
|
|
|
5. 通过执行安装路径的bin目录的vivado来启动
|
|
|
|
|
|
6. 安装Xilinx Platform Cable USB II 下载器驱动
|
|
|
|
|
|
1. cd /tools/Xilinx/Vivado/2021.2/data/xicom/cable_drivers/lin64/install_script/install_drivers
|
|
|
|
|
|
2. sudo ./install_drivers
|
|
|
|
|
|
3. lsusb 检查安装的usb设备
|
|
|
|
|
|
4. 重新拔插后显示 Bus 005 Device 011: ID 03fd:0008 Xilinx, Inc. Platform Cable USB II

## tips
|
|
|
|
|
|
|
2022-03-27 17:56:02 +08:00
|
|
|
|
* jtag的reset引脚要设置正确 jtag_trst_n 低电平复位
|
2022-03-20 17:06:02 +08:00
|
|
|
|
* 仿真的时候jtag的tclk不能太快，要低于soc的clk
|
2022-03-27 17:56:02 +08:00
|
|
|
|
* SweRV启动/复位后程序从`reset_vec`(0x80000000)开始，遇到错误（code=0），就会跳到mtvec(中断向量表)指示的地址
|
2022-03-20 17:06:02 +08:00
|
|
|
|
* 物理仿真的时候 adapter speed 不能太快
|
|
|
|
|
|
* data段放到0x200太小，GDB调试RISCV至少要4K的程序空间？
|
|
|
|
|
|
* soc的ram和rom直接接到了lsu和ifu，和DCCM/ICCM无关
|
2022-03-27 17:56:02 +08:00
|
|
|
|
* program.hex 用于 $readmemh 必须以空行结束
|
|
|
|
|
|
|
|
|
|
|
|
## Todo
|
|
|
|
|
|
|
|
|
|
|
|
* gdb怎么复位soc
|
|
|
|
|
|
* gdb没有把程序加载到mem，ifu还是用老代码
|
|
|
|
|
|
* mem分bank后，怎么加载，用于仿真=>for循环分别加载
|

|
|
|
|
* Quasar升级scala版本发现openocd运行不正常
