FS26:Is the MCU fault recovery strategy only effective for S32K3xx?

[Kojimaa]

Hi,

  Im using FS26xyD with TC3xx and was enabled by OTP, but this mechanism seems to be ineffective. When FCCU input is activated, RSTB asserted immediately .

Thank you in advance

In your MCU side there is no FCCU pins,right? if no FCCU,you need disable FCCU function in SBC side.

Hi,

   TC3XX has an FSP similar to FCCU that can be monitored, but this MCU recovery strategy seems do not work.

For the SBC side if you want to use the FCCU function, you need do below two points:

1: hardware connection: according the FCCU_CFG bit setting to design this connection

2: registers setting:

FS_I_SAFE_INPUTS register and FS_I_NOT_SAFE_INPUTS (0x48)
