A memory hole! what does this mean?

[Pavel A.]

Dear experts,

I'm debugging a program on STM32H753 in Atollic TS 9.3 and see something weird.

It looks like unreadable hole in D1 RAM from 0x24013880 to 0x24013BAF

Is this artifact of the Atollic's debugger, or???

The chip runs at 400 MHz

Hi,

I tried to view the same area in my H755 and there is no problem.

I'm using STM32CubeIDE.

Can the firmware running on the MCU access it?

Is it reproducible after you power cycle everything?

Doesn't reproduce after restarting everything. Looks like bug of the debugger...
