I not to able programming the NUCLEO-H743ZI2

[CDrey.1]

I have an NUCLEO-H743ZI thats works fine. So now i have buy a new NUCLEO-H743ZI2.

With the samge Firmware i not able to programming the flash.

I have upgrade the ST-Link V3 with the latest FW. But nothing helps.

When i try to programming the Flash i get follow error:

Erase Done.

Programming Done.

Contents mismatch at: 08000040H (Flash=FFH Required=C7H) !

...

Contents mismatch at: 080000E3H (Flash=FFH Required=08H) !

Too many errors to display !

Error: Flash Download failed - "Cortex-M7"

But what am I doing wrong?

Thanks for Help.

What software you use to program? Try the latest CubeProgrammer. Check your USB cable.

Thanks Pavel for your replay.

My IDE ist Keil uVison V5.26 this i use to program the Nucleo-H743ZI2.

I tried also the latest Keil V5.29. But i had the same effect.

The USB Cable ist good. I use the same to program the Nucleo-H743ZI and it works fine.

When i use the CubeProgrammer i can program the Nucleo-H743ZI2. But why not with Keil?

So this looks like Keil issue. They have good tech. support.

In Keil make sure you pick the right Flash Programming Algorithm, type of error suggests banking mode wrong/mismatched, or connection speed too high

Thank you for your answers.

You are right, Keil uVision 5.26 does not support STLink V3.

I reinstalled Keil 5.29 and updated the ST-Link driver, now it works.

Many thanks for your help.
