hi
I am working with nordic nrf52810 soc, when i flash code using stlink v2 i am getting "Internal command error", all my connections are correct. i can see my stlink connected inside debug in keil. on the other hand i am able to program successfully stm32f103 using the same ide and programmer.

You need to give more details - where, exactly, do you get that?
Note that you can copy & paste from the Build Output window...

Also, as the name ST-Link suggests, it is specifically designed by ST for their processors; it is not supported for other manufacturers' devices (although people have "hacked" it) - so you're really on your own for support with that.
I would strongly suggest that you use a supported debug probe; the most obvious choice would be the J-Link embedded on a Nordic Dev Kit - which is designed & supported for programming external targets.

You would hope so - that is an ST chip!
I can't see my device inside SWDIO in debug tab
You've added the screenshots, but you haven't said when, exactly, that error box appears.
Again, copy & paste the text from the 'Build Output' window.
when i flash code to chip this box appears, also i cant see my device in debug tab which you can see in other screenshot.

As I said, the ST-Link is specifically designed for ST devices, so I wouldn't be surprised if it's trying to do some ST-specific things - which are bound to fail on a non-ST chip.
Is it really worth the effort of battling this, or would your time be better spent using a supported debug probe?
i am using nordic ble module which dont have on board j-link, i have seen few post in which people have programmed nrf51822 using stlink, i dont know why stlink is not detecting this IC.

again, the J-Link on a Nordic Dev Board can be used for external targets.

Yes, that's exactly what I said - but it's not the intended or supported use of an ST-Link.
If you want to go off-piste, you need to thoroughly understand what you're doing and how to make the necessary hacks
thanks for your guidance, i got jlink now, everything is working fine.
