STM32F723 ST-Link FLASH memory-size and erase error

1. ST-Link reports the wrong size for the Flash memory. ST-LINK-Utility reports 'Unknown' and the ST-Link CLI reports 4095 kBytes.

2. ST-Link CLI can't erase memory sector 1 at 0x08004000. When using the commandline-switch -SE 0 1 st-link cli reports the following Error:

Memory Sector @0x8000000 erased

Memory Sector @0x8004000 is not erased. Verify the memory protection.

Verifying the Option-Bytes the memory is not protected!!!

Only a full chip erase can resolve this problem.

Hi

Reuss.Erwin

‌,

Are you using the last version of STLink Utility?

Yes of course. I am always using the latest version from the ST homepage. ST-Link Utility v4.0.0.0, STLinkUSBDriver.dll v4.4.0.0 and ST-LINK_CLI.exe v3.0.0.0.

All works perfect, wenn i do a full erase before flashing. But this always takes a long time.

A new version of ST-Link software is online. The STM32F723-bug is fixed. Thank you.
