S32K312 HSE recover

[BigSun]

Hi, I have a problem about HSE.

I have installed HSE FW 1.13.0 0.2.40 before via S32K3_HSE_DemoExamples_1_0_0 S32K344_HSE_FW_INSTALL.  but suddenly When I use HSE module, hse firmware seems lost, HSE_MU_GetHseStatus return 0. so HSE is not HSE_STATUS_INIT_OK. How to recover HSE?

I tried to recover according to MU Restore FW_EN.pdf, but it does not work. data at 0x4039c028, 0x402ac400 show ?, when write DCMRWP1 0xA500000000, run and stop but MU0 RR0 register does not change.

I have made a installation project at https://github.com/chenzch/WT_HSE_Installer_312 . It can use mu interface to install if there is something wrong with the normal way. You can try it.
