建议您手动来执行用户指南内的Unsecuring procedure。根据您的描述，应该是GEL运行不正确

1.2.3.3 Unsecuring Considerations for Devices With/Without Code Security

就是参考 1.2.3.3 Unsecuring Considerations for Devices With/Without Code Security 内的内容和相关步骤

A device with code security should have a predetermined password stored in the password locations (0x33 FFF8 - 0x33 FFFF in memory). In addition, locations 0x33 FF80 - 0x33 FFF5 should be programmed with all 0x0000 and not used for program and/or data storage.

请您先查看一下0x33 FFF8 - 0x33 FFFF的值是否是全0x0000

若是全0的话，就使用下面的步骤来解锁

The following are steps to unsecure this device:

1. Perform a dummy read of the password locations.

2. Write the password into the KEY registers (locations 0x00 0AE0 - 0x00 0AE7 in memory).

3. If the password is correct, the device becomes unsecure; otherwise, it stays secure.
