Hi,
I am working with stm32f303k8t6 and I programming stm32 with st link v2 mini. First I used this programmer normally but last week it was fail. And I bought a new st-link v2 mini. Now I try to programming with this new programmer but it send "Internal Command Error". I am not programming my stm32(Only one time I succeed programming my board).
Can anybody help me with this issue?
I try st link utility and it did not work. It not connect st link utility(I try two programmer). Now I try another programmer and it send "No target connect" error. I try "reset button" and "connect under reset" mode in dubug but it did not work.
If it doesn't even work with the ST-Link Utility, then this has nothing to do with Keil.
Do you have any teachers / supervisors / FAE who can assist you locally?
Hi, I use this programmer a lot of time but after it did fail and I bought 2 st-link v2 mini. And a few times it was work but generally it is not working. Now programmer send "Target not connect" error.
This is my programmer link www.electrodragon.com/.../
Beware that not all these cheap Chinese knock-off ST-Links have the same pinout - so check that your new ones match the old one!
Have you tried to contact electrodragon for support? (it's a long shot, but you never know ...)
Have you tried a genuine ST-Link?
Or any other debug adaptor?
What about a Nucleo or Discovery board ... ?
If neither pod can attach to the target consider if the target is in fact powered and functional, real hard to talk to a dead device. Check the regulators and supply voltages.
and all connections are physically intact...
Hi, I try my code in nucleo board(stm32f303k8t6) and it was work. But in my board (only stm32f303k8t6) it is not working. Maybe Andrew you are right, I will get new programer and I try after I write in there stiuation.
... could also indicate a hardware problem on your board - as Westonsupermare Pier suggested,
Hi, I bought new st link v2 and i try but it still say "no target connected". I am sure my hardware because I program this hardware a lot times. Could someone help us? Thaks
That makes no sense!
Surely, the fact that you've used it "a lot" only increases the risk that it had been worn or damaged ?!
"Could someone help us?"
Again, you really need someone local - who can sit next to you, and see exactly what you are actually doing, and see exactly what hardware you actually have, and see exacty what state that hardware is in, etc, etc.
And, again, the fact that it doesn't even work with the ST-Link Utility shows that this has nothing to do with Keil.
Pull the BOOT0 pin high, reset and try to connect and erase while your code isn't running.
