SCST m7_scst_spfpu_convert_test1 fails every now and then but it passes most of the times. I have debugged the assembly code and I see that some times the S0 and S1 are not getting the correct values when arriving to the m7_scst_spfpu_convert_test1_check_fpdscr section. Also, test m7_scst_fetch_test fails but with less frequency. This I can only avoid it by disabling all the OS interrupts before executing the SCST tests but I can't do that always, the user manual says I can leave the Interrupts enabled and that the library should take care the interrupts but this issue happens every 100-300 test executions. How can I fix this issue without disabling all the interrupts before executing all 50 tests? ... View more

Hi There, In developement of Safety Mechanisms, which is the right  scheduling sequence ? I suppose that SM2 run  before SM1. Is it correct? Or is  it true  the opposite way? Or there is no a fixed order ? For example:  "SM2.CMU.sCheck" should be run before "SM1.CMU_FC" and "SM1.CMU_FM", because first  is necessary to check if fhe hardware is ok, then it is possible to use CMU for check frequency and measure period. Is it righi ? If yes, is it for all SM1 and 2? Best Regards, Fabio ... View more

In eMcem_init, the function status return is E_NOT_OK.Through the useing step debug find eMcem_Fccu_ReadFaultStatus return FCCU_FAULT_ASSERTED, so eMcem_init return is E_NOT OK.But if starting the eMcem_init start to step debug run function, eMcem_init return is E_OK. Please anyone know how to resolve this issue, Thanks. ... View more

Hello NXP Team, SM_133 and SM_137 require redundancy at HW. In our system(ASILB), ADC and GPIO inputs are safety relevant. Both ADC and GPIO inputs are used to monitor the power supply. ADC check the voltages on power rails are within expected range and GPIO indicates error status of PMIC. Do the assumptions on redundancy apply for ASILB?  Will these be necessary if below SW mechanisms are implemented ADC - ADC tests suggested in manual. GPIO - Stuck to Battery/GND checks at startup. ... View more
