Hi Support,   Customer (AEV) need help with identifying suitability of the NXP parts for our mission profile.  Mission profile for their product is for a total operating hours of 35000 hours,   They are checking if we could guide them how to convert the base failure rate for a mission profile of 35000 hours.  Or provide them findings based on S32G399ASCK1VUCT.   Regards, Marcus  ...查看更多

Customer is Aurora.   They need guidance with an issue we are encountering when implementing safety mechanism SMA2/SIR_41 in the VR5510 Safety Manual. The safety mechanism is to ensure that the RSTB path between VR5510 and S32G is intact. Initially, they implemented it as follows:       The problem is RSTB_EVENT was always 0 after S32G came out of a RSTB reset. According to the safety manual, this bit cleared only on a POR on PMIC. Apparently, the PMIC is configured to  assert PGOOD when RSTB is asserted (VR5510 SM, 5.2.11.1). So when the PMIC asserted RSTB upon the RSTB request from MCU, it also asserted PGOOD (both RSTB_EVENT and PGOOD_EVENT in FS_SAFE_IOS were set), which power-on reset the MCU, which also power-on reset the PMIC, which cleared RSTB_EVENT. This means that RSTB_EVENT can’t be used as the persistent part of their RSTB-check state machine. They could replace RSTB_EVENT with flash, but at the cost of wearing out the flash. Do we have any suggestions for this?   -Randy Krakora ...查看更多

Hello,  To implement this SM is there any configuration needed in software? Is the below measure in software (Data pattern write and read to a known location)need to be implemented ?  ...查看更多

Hello, I am injecting the stack overflow error of S32K3XX MCU, and after successfully injection of error DebugMon_Handler exception triggering. I have a query Related to recovering methods. during testing observed only After power on reset MCU is able to recover from Stack Overflow exception. Please let me know is there any other methods of recovery. Thanks ...查看更多

Customer is Ford. s32g3.   Safety manual has the following requirement to check DBG mode in PMIC before release FS0B, I can see that the PMIC init code is already doing it. Is this good enough ? or do they need to write something in application? It looks like the code checks it and if nonzero, tries to set it to 0, and appears to verify debug mode has been exited.     -Randy Krakora   ...查看更多
