S32K148 MCU用J-LINK错刷Flash,再用J-LINK链接发生如下错误，JLINK unsecured已没用,怎么解决？

Connecting ...

- Probe/ Programmer firmware: J-Link V9 compiled Dec 13 2022 11:14:50
- Probe/ Programmer S/N: 25994751
- Device "S32K148" selected.
- Target interface speed: 50 kHz (Fixed)
- VTarget = 3.301V
- ConfigTargetSettings() start

- InitTarget() start
- SWD selected. Executing JTAG -> SWD switching sequence.
- Protection bytes in flash at addr. 0x400 - 0x40F indicate that readout protection is set.
For debugger connection the device needs to be unsecured.
Note: Unsecuring will trigger a mass erase of the internal flash.

- Executing default behavior previously saved in the registry.
- Device will be unsecured now.
- Timeout while unsecuring device. Erase never stops.

Hi@dongkuili

首先不见得保证能恢复，因为加密段被你写入了错误持续值，可能并不支持mass erase擦除

可以阅读该文档6. S32K1xx系列MCU芯片锁死(lockup)现象
