In Memory Browser all I see is ?????? for STM32F401RE

[Gogo_91]

I was performing simple arithmetic calculation, and wanted to check the data gets stored in Flash and SRAM memory.

While checking the memory browser all I see is ?????. Could anyone guide me, what's the issue here?

You have to halt for it to update ?

[Gogo_91]

While suspending, it shows opcodes at 0x08000000, which is starting memory address for flash, but if you look at the screenshot, still it shows ??? mark at other various memory address.

Also, for SRAM memory, it shows the same.

And your in run mode again - so it cannot show ram data; only while cpu halted.

So difficult to understand ?

Perhaps share more details about your board and your ST-LINK, is that authenic? Does this work from STM32 Cube Programmer tools more directly?

Is this a NUCLEO-F401RE ?

Sorry, I'm new to this. But please refer to the screenshot attached.

Yes this NUCLEO-F401RE microcontroller.

Note that Nucleo is a board - not a microcontroller.

The microcontroller is the STM32F401RE chip mounted on the board.

Ok, thanks for the correction.
