Hello,

 http://www.keil.com/support/docs/3778.htm describes a nasty bug when single stepping in Cortex M7 up to r0p1. I am hit by this bug with my F746 boards, as the core revision is  r0p1. Two questions: - will STM32F76 have a newer core revision? - will  STM32F74 get a chip revision with a newer core revision?

Current errata suggest they all use the older core

Will have to see what's delivered in May, though I will ask at the seminar when we might expect a refresh.

Thanks for the reply. The Errata for STM32F76xx clearly says: revision r1p0.

So the new chips are not affected by that bug.
