External ST-LINK/V2 programmer/debugger with B-L072Z-LRWAN1 Discovery kit
Hi,
I have bought:
1)a B-L072Z-LRWAN1 Discovery kit (with on-board ST-LINK/V2-1 programmer/debugger)
2)a separate ST-LINK/V2 programmer/debugger.
I have downloaded and installed on my PC (windows XP) the following tools:
1) STSW-LINK009 (ST-LINK/V2 USB driver)
2) STSW-LINK004 (STM32 ST-LINK utility)
However, when I try to connect the target by using the separate ST-LINK/V2 programmer/debugger, I obtain the error message
'' No ST-Link found with the expected serial number. check ST-Link selecting options or connect only one ST-Link ''.
The ST-LINK/V2 status led is RED (communication between the PC and ST-LINK/V2 is established.
To perform this trial, I have:
1) removed the two CN8 jumpers of B-L072Z-LRWAN1 Discovery kit (to switch to the external programmer/debugger)
2) connected the B-L072Z-LRWAN1 Discovery kit with the PC by an USB cable through CN7 (only for power supply)
3) connected the ST-LINK/V2 with the PC by an USB cable
4) connected JTAG/SWD connector (20 pin) of the ST-LINK/V2 to SWD connector (6 pin) CN12 of the B-L072Z-LRWAN1 Discovery kit as in the following:
B-L072Z-LRWAN1 Discovery kit (CN12) SWD connector (20 pin) of ST-LINK/V2
Pin no. Pin name Pin no. Pin name
1 VDD_TARGET 1 MCU_VDD
2 SWCLK 9 SWCLK
3 GND 10 GND
4 SWDIO 7 SWDIO

Please suggest the corrective action required
Thanks
