Hi NXP，
1. Why does the S32K344 run Bist_Run(BIST_SAFETYBOOT_CFG) into Hardfault?
2. I am using standby RAM to store data, does this affect BIST?
Best Regards,Li 3
Hi Li 3,
BIST will reset FCCU and reset SRAM content, thus SRAM ECC need be re-initialized after ST_DONE functional reset. Considering that you use standby RAM, please check if the hardfault is a Busfault caused by the ECC RAM not being initialized.
Have you checked the ERR_STAT register?
By the way: The discussion in STCU2 internal errors and SPD-BIST BIST_DIAGNOSTIC_CFG may be helpful
Best Regards,Robin
