We have some questions regarding errata e4396 for the MPC5674F processor. While the workaround mentioned in the errata is trivial, the implications and cost of rolling out a new software revision that includes the workaround to our customers can be quite large. Any help that you can provide to better understand the errata and the likelihood of occurrence is much appreciated
Hi,
1. I can't comment.
2. There are more conditions which need to be met, so it may affect both kind of codes.
3. Yes, this leads to execution of wrong instruction which may completely destroy user application.
4. There is no way to quantify the probability of the occurrence. It requires an alignment of many internal conditions that the customer cannot control. If the condition occurs, it is likely to occur almost all of the time, however, just because the issue has not been seen, does not mean it may not occur in the future.
5. The workaround was confirmed as correct.
Regards,
Lukas
