Hello All,
If yo are using the STLINKV3 you will need a level shifter as well. This is because the sensortile box is expecting 1.8V level signals however the STLINKV3 outputs signals at a 3.3V level this may be one of the reasons for the error you are getting.
As of right now ST doesn't provide the level shifter part that is required for this setup. Therefore it is recommend to use the STLINKV2 debugger instead along with the 14 pin flat cable that get in the V3 set.
My sensortile box setup includes the following components:
- STLINKV2 debugger -> https://www.digikey.com/product-detail/en/stmicroelectronics/ST-LINK-V2/497-10484-ND/2214535
- Adafruit JTAG to SWD Cable Adapter Board -> https://www.amazon.com/gp/product/B00OLGTDXE/ref=ppx_od_dt_b_asin_title_s00?ie=UTF8&psc=1
- 14 pin to 10 pin flat cable -> https://www.st.com/en/development-tools/stlink-v3set.html#sample-and-buy (I wasn't able to find a purchase link for just the cable so I purchased the V3 set that includes this flat cable)
- One Micro USB data cable
- One Mini USB data cable
Important: The connection(orientation) of the 14pin cable is very important. The cable should be attached as shown in the figure above i.e. the cable extends above the battery. If you connect the cable in the opposite direction i.e. facing away from the battery then you will get an error stating "STM target not found".
Hope this was helpful
Sincerely,
