Dump of the base bootloader shipped together with CH32V003
The dump comes from the first 1920 (0x780) bytes of the System Memory of a CH32V003F4U6. It should be compatible with all the CH32V003 series.
This can be uploaded on the boot memory using WCH-LinkUtility and setting the memory address where to upload the firmware to 0x1FFFF000.
All the binary code is developed by WCH https://wch-ic.com/
