STM32H563Zi: Error in initializing ST-LINK device.

[jowakar122]

Hii,

I am using Nucleo-H563Zi. Suddenly I got  "Error in initializing ST-LINK device" Reason: Unknown. Please check power and cabling to target. What I have tried to solve this:

. Connected pin BOOT0 and VDD and tried to connect to cube programmer.

. tried using power down and under reset mode to connect 

none of the above helped me to connect and earse the full chip.
I have gone through every thread related to this problem but none helped. I have ran out of options. It would be great if someone assist me in this problem.

Hello @jowakar122 ,

did you change the default OptionBytes with cube programmer before this issue popped ?

do you have a firmware on your board related to security, OptionByte software configuration or any other protections?

did you try to connect using another cable? 
Regards

I changed the product state value to 17. 
I was trying to implement OEMiROT_BOOT on my device by following: How to start with OEMiRoT on STM32H573 and 563–Arm® TrustZone® enabled. Yes, I tried connecting using another cable.

I also tried to change the product state value but can't

Hello @jowakar122 ,

did you try to execute the regression script as described in the wiki page section: 2.6.1. Full regression from Provisioned state using a script (included in the STM32CubeFW)
did you follow the necessary steps for the provisioning phase described in the WIKI or you changed the state manually via cubeProgramer ?
