is STM32F7 has DFSR register?

Hi!

I try to understand debug information after hard fault. RTOS dump DFSR register (and some other) after fault to UART. This register is not present in PM0253 programming manual, but there is definition in source code (core_cm7.h address is 0xE000ED30), also this register is described on correspond ARM web page doucmentation.

So, is there description of the DFSR register in manuals by ST? Is there this register in MCU?

Hello,

I don't know why it is not included.

I see it in the Control System Block while I'm debugging, but not in PM.

I've just submitted a ticket.

It exists in the M7 core. I don't know why it's not included in PM0253.
