- GD官网下载GD32E23x库
在文件夹中整理 - 更新库目录 Eclipse软件在点击 之后出现了无法下载的情况PDSC这里选择文件Ignore All所有可以下载的快速完成pdsc文件。 这些PDSC保存文件地址index.pidx中 从https://www.keil.com/pack/index.pidx下载index.pidx， index.pidx文件部分
index.pidx文件可以保存在内存中.cache中间没有保存。 然后按照index.pidx中PDSC逐一下载网络地址PDSC下载一个生成文件 .*.size用来标记文件PSDC文件大小。 eclispe下载完所有pdsc读取所有文件后PSDC文件，提取部分信息写入到 .content_https___www_keil_com_pack_index_pidx.xml，并分析文件和CMSIS-Packs在界面上可以看到已安装的库(包括自己的解压库)。
注：在断网状态下更新库目录， .content_https___www_keil_com_pack_index_pidx.xml内容将被清空。
- 更改.content_https___www_keil_com_pack_index_pidx.xml文件 添加如下：

把修改后的.content_https___www_keil_com_pack_index_pidx.xml放到 .cache文件夹中 错误步骤： 不要自己解压缩库放在CMSIS-Packs文件夹中，这样虽然可以看到已安装 但是在工程的属性中，查看device是看不到库的，因为没有install过程，.installed_devices_boards_books.xml中没有记录已安装的库。 正确步骤： 把以下文件复制到 .cache文件夹中，右击install。 在device中查看，已经添加好了。我们看到实际device中查看实际是根据.content_https___www_keil_com_pack_index_pidx.xml和CMSIS-Packs存放的PDSC文件，完成检索。 eclipse Console显示信息如下：

库安装好之后，debug时可以看到外设的寄存器。 4. 以后就不能再随意更新库目录了 会把.content_https___www_keil_com_pack_index_pidx.xml还原掉。 实际实验更新过后，之前安装好的库，因为 .content_https___www_keil_com_pack_index_pidx.xml文件改变后库目录和device中查看都已看不到。 但是Devices里没有了。 在CMSIS Packs中Remove后再install后，发现又回来了。
