从 https://github.com/hdscmcu/pack 获取 HDSC.HC32L130.1.0.1.pack，这是个 zip 包，改名为 L130.zip 后 unzip 解压：

<source lang=bash>
$ find .
./Device/Include/HC32L130E8PA.h
./Device/Include/HC32L130F8UA.h
./Device/Include/HC32L130J8TA.h
./Device/Include/system_hc32l130.h
./Device/Source/ARM/startup_hc32l130.s
./Device/Source/main.c
./Device/Source/system_hc32l130.c
./Flash/FlashHC32L130_64K.FLM
./HDSC.HC32L130.pdsc    # XML 描述文件
./SVD/HC32L130E8PA.sfr
./SVD/HC32L130F8UA.sfr
./SVD/HC32L130J8TA.sfr
</source>

将 FlashHC32L130_64K.FLM 改名为 HC32L130_64K.FLM，放在：
<source lang=bash>  
$ find /c/Program\ Files\ \(x86\)/SEGGER/JLink/Devices/HDSC/
/c/Program Files (x86)/SEGGER/JLink/Devices/HDSC/HC32L130_64K.FLM
</source>


/c/Program\ Files\ \(x86\)/SEGGER/JLink/JLinkDevices.xml 增加：

<source lang=xml>
  <!-- Huada (HDSC) -->

    <ChipInfo Vendor="HDSC" Name="HC32L110x4"  WorkRAMAddr="0x20000000" WorkRAMSize="0x800" Core="JLINK_CORE_CORTEX_M0"/>
    <FlashBankInfo Name="Flash_16K" BaseAddr="0x0" MaxSize="0x4000" Loader="Devices/HDSC/HC32L110B4_C4.FLM" LoaderType="FLASH_ALGO_TYPE_OPEN" AlwaysPresent="1"/>
  </Device>

    <FlashBankInfo Name="Flash_32K" BaseAddr="0x0" MaxSize="0x8000" Loader="Devices/HDSC/HC32L110B6_C6.FLM" LoaderType="FLASH_ALGO_TYPE_OPEN" AlwaysPresent="1"/>
  </Device>
  <Device>
    <ChipInfo Vendor="HDSC" Name="HC32L130"  WorkRAMAddr="0x20000000" WorkRAMSize="0x2000" Core="JLINK_CORE_CORTEX_M0"/>
    <FlashBankInfo Name="Flash_64K" BaseAddr="0x0" MaxSize="0x10000" Loader="Devices/HDSC/HC32L130_64K.FLM" LoaderType="FLASH_ALGO_TYPE_OPEN" AlwaysPresent="1"/>
  </Device>
</source>

则可使用 J-Flash 烧写：

* MCU 选 HC32L130，SWD 4000KHz
* Target -> Connect
* Target -> Production Programming（快捷键 F7）
* Target -> Manual Programming -> Start Application（快捷键 F9）
