Hello,
I have problem with BIST configuration.  
Processor S32K322, SAF version:  *   SW Version           : 1.0.4 *   Build Version        : S32_SAF_1_0_4_2023122

1. LBIST expected value is:

LB_MISRELSW0 = 0x73D0 53B5

LB_MISREHSW0 = 0x253B 0C27

Which corresponds to the value from file „Bist_SpecificTables_S32K3XX.c”

Value of this register after Bist_Run(BIST_SAFETYBOOT_CFG):

LB_MISRRLSW0 = 0x307A 7C25

LB_MISRRHSW0 = 0x15E4 11A4

Why value which is readed is equal for expected value for S32k342? Because this mean that LBIST_Test is fail.

After executed function: Bist_GetExecStatus() after Bist_Run() i got value BIST_INTEGRITY_FAIL

  1. MBIST configuration.

MBIST test also too have a fail.  Because expected value is:  0x0000 01F0. This value was read from: SAFETYBASE_REG_READ32(BIST_STCU_MB_END_REG(0U));, file Bist_General_S32K3XX.c line 222.

Value of MBIST after Bist_Run: 0x0000 01FE
