TIDM-DC-DC-BUCK: Sensing is strange.

Part Number: TIDM-DC-DC-BUCK
Other Parts Discussed in Thread: LAUNCHXL-F280049C, BOOSTXL-BUCKCONV, , C2000WARE

Hi.

After purchasing BOOSTXL-BUCKCONV and LAUNCHXL-F280049C, I am testing while looking at the document TIDM-DC-DC-BUCK(tidu986a).

Compilation-Upload-Debugging environment settings, etc. proceeded normally.
When 9V is applied to BOOSTXL-BUCKCONV, it says that the voltage applied to the BUCK_vInSensed_Volts variable is measured, but it is not displayed.

So I thought of it as a hardware problem and measured the voltage with a multimeter. The voltage of about 2.4 was coming out correctly due to the voltage distribution.

What is the cause of the above problem?

The S/W development environment is as follows.
Code Composer Studio: v10
Compiler version: TI v20.2.1.LTS
C2000Ware_DigitalPower_SDK_3_02_00_00

In addition, when uploading the firmware to LAUNCHXL-F280049C, the JTAG(XDS110) version is displayed as different from the SW version I use, and there was a JTAG(XDS110) firmware update guide.
So I updated the JTAG(XDS110) version.

Thanks.
