MPC5777C write a flash page

[tomaszjanik]

Dear all,

regarding an issue on Bolero, where the flash controller writes a page backwards (i.e. writes the byte with the highest address first), is the Cobra somehow affected from this phenomenon?

Thank you in advance for your support!

Best regards

I have never heard about the issue. Could you provide a details about that?

Hello David,

thank you for your answer. I have wrongly mentioned the microcontroller: according to Autosar vendor Issue Report regarding Fee_Read operation, the issue is known to occur on SPC564B74. I did not experience this issue by myself, I’m just evaluating the issue report from the Autosar vendor (see below).

I’m not sure how far is the NXP PPC family and specially the Cobra affected (if at all) from this issue.

Best Regards,

Tomasz Janik

SPC564B74 is ST part number. Thus I would apparently recommend STMicro support:

I have asked our AUTOSAR expert, being told such issue is not known to us.
