Ender-3-V3-SE-MCU-Dump

FW: 1.0

Dump of the CR4NS200320C13 motherboard microcontroller for recovery when replacing the GD32F microcontroller.

At your own risk!

1. You need a ST-Link USB adapter
2. ST-Link Utility

If the controller does not allow you to connect on (ST-Link Utility) to it you need to apply +3.3 before R41 to switch to boot mode.

1. !To flash the firmware via ST-LINK, you do not need to apply the main voltage (+24). All voltages must be taken from the ST-Link adapter!
2. !Do not update the firmware with SWD disabled; you will not be able to connect again via ST-LINK without boot mode (+3.3 befor R41)!
3. !Be sure to do a full dump(with correct size from 0x08000000 to real end address of memory) before any manipulations with the MB!
