Access denied appears when burning

Currently using SF32LB52-MOD-1N16R8, the development board model is SF32LB52DevKit-LCD-V1.2.1. I’m using the VS Code plugin for flashing, with a baud rate of 1,000,000, and it keeps showing “Access Denied”.

The device manager also shows the device.

Help! Help! @zhenpeng

Use the serial port tool, connect to the line that has 52x_BOOT, check it, then reset to see if the log enters boot mode. Once it enters, disconnect the serial port tool connection, and then try flashing again.
