Fatal error: The selected device does not match the target device

Hi community,

I am using STM32F103C8. with IAR ARM v7.80.3. When I tried to debug my project with STLINK (FW: V2J28S7), I got this error 

[Mon Jan 09, 2017 13:50:25: Fatal error: The selected device does not match the target device Session aborted! ]

In IAR project setup, target device is set to 'ST STM32F103C8' which is exact to the chip on the board. However what STLink detects (when using ST-LINK utility) and it shows :

'Device: STM32F 10xx Medium-density

Device ID:0x410

Revision ID X

Flash size 64KB'

Is it possible that debug is aborted because the ST-LINK failed to detect exact model of the board?  In old version of IAR, i could select generic '

STM32F10xx', instead of specific model  'ST STM32F103C8'

Thanks,

Chayut

Dear

‌,

Thanks for highlighting yourissue. This isthe same problemas mentioned in this

https://community.st.com/0D50X00009XkaEESAZ

. So, you can try with old version of IAR ARM as v7.1.

I would recommend you to contact IAR ARM for support (

Hi,

I'm still having the same problem listed above even though I downloaded t

he patch for 7.80.3 on the IAR page. Is there any clue about the solution?

IAR has released 7.80.4 which fixed this issue for me.

I had the same problem on STM32F769 -DISCO.

I try Project->Options->General Options->Target->Processor variant and changed to Core M7

This worked for me.

Maybe the wrong flashloader file is used too. Had this on DISCO too.

Hi,

You should use the last version

http://supp.iar.com/Updates/?product=EWarm

which contains fix for debugger connection when using some ST devices as ST-Link.

Please keep us informed about your update.
