[经验分享] Linux 搭建 RVB2601 开发环境

iysheng 2022-5-11 17:40 楼主

### Linux 下开发环境搭建

RVB2601 是一款基于 E906 的 RISC-V 生态芯片，最高主频 220MHz，RV32IMACX 指令集

#### 搭建流程

最开始按照 **RVB2601 资源下载** 下载的 sdk,根据 sdk 中的 readme,执行发现编译的时候出现各种错误：
* 宏为定义
* 数据类型未定义
* 缺少头文件等

通过提交工单，了解到了正确的编译方法：

可能初次安装的时候会碰到 ``product 命令找不到的现象``，根据[yoctools安装后无法找到product工具](https://yoc.docs.t-head.cn/yocbook/FAQ.html)，可以这样做：
``` bash
sudo pip install --no-binary=yoctools yoctools
```

然后编译就正常了。
``` bash

#### 程序烧录
通过 [工单202205090014](https://occ.t-head.cn/people/my/work-order/details?id=4044173371767267328) 解决了这个问题，可以通过 ``make flash`` 可以完成程序下载。

程序烧录，需要使用 **Linux 版本的 T-Head-DebugServer**，目前最新版本的 Linux 端的 T-Head-DebugServer 是 **T-Head-DebugServer-linux-x86_64-V5.14.2-20220415.sh.tar.gz**，下载执行该脚本的安装，就会在 Linux 端安装上 ``DebugServerConsole``。

上述工具的安装方法：
``` bash
▸ sudo ./T-Head-DebugServer-linux-x86_64-V5.14.2-20220415.sh -i
Do you agree to install the DebugServer? [yes/no]:yes
Set full installing path:
This software will be installed to the path: (/usr/bin)? [yes/no/cancel]:yes
Installing ...
Done!
You can use command "DebugServerConsole" to start DebugServerConsole!
(NOTE: The full path of 'DebugServerConsole.elf' is: /usr/bin/T-HEAD_DebugServer)
```

接下来准备烧录程序：
1. 首先运行 ``DebugServerConsole`` 
2. 在工程目录即 ``solutions/ch2601_helloworld``下执行 ``make flash`` 或者 ``make flashall`` 烧录部分镜像或者全部镜像

但是开始发现程序没有正常运行，通过不断麻烦平头哥小二咨询，最后发现是跳帽管脚跳的不对导致的。

具体体现在：

我拿到板子的时候，debug 口链接的是 w800,导致下载程序观察串口打印没有发生变化，通过修改 debug 链接到 RVB1062 就可以正常看到打印信息了。

![](https://s3.bmp.ovh/imgs/2022/05/11/8d8c1783ef3c478b.png)

至此，Linux 端对 RVB1062 开发和烧录的环境就搭建好了。
