Keep getting "Could not verify ST Device" on original ST chip and J-Link under CubeIDE

[bully]

Hello,

I'm getting this error that is related to using STM32 clones.

But we use original chips from ST from well known distributors, why do I get this error ?

Sometimes unplug/plug helps, sometimes Erase Full chip also helps, but I'm repeating those steps all the time and lose a lot of time.

In same moment, when CubeIDE cannot verify chip, J-link utilities work normally.

If ST can't get verification to work reliably, why is it present anyway ?

Regards,

Rob.

Hello Rob!

Sorry about the delay in response, I was out-of-office.

What device are you using? If you have a reliable step-by-step guide to recreate the issue I'd be happy to create a ticket to get the devs to take a close look at the verification process.

Hello,

let me describe situation a bit. Verify error happens quite often, then I usually:

• try to unplug/plug J-Link on USB
• if doesn't help, then I power off/on our custom HW and repeat step 1
• if doesn't help, then I run J-Flash lite utility to erase full chip flash (it always runs, because it doesn't check), then I repeat first two steps
• in large majority of cases, last above step works, but usually another flash program cycle is again unsuccessful.

I attach logs, and it seems quite obvious (my guess) that chip returns 0 on ID verify step (ReadAP 0x2). But how can Erash Flash step help in this case ?

I understand that you want to check chips for originality, but if that causes troubles on original chips, then please give as possibility to switch this feature off,

otherwise we will have to switch to other development tools that don't have this problem.

Regards,

Rob.
