DRIVE OS Version: 7.0.3
Issue Description:
Hello,
I am working with Drive OS 7.0.3 on the DRIVE Thor DevKit . During the board bring-up/check, I executed the showvoltages command on the Safety MCU console and observed significant discrepancies between the actual voltages and the expected ranges defined in the FW.
Output Log:
Plaintext
NvShell>showvoltages
Info: Executing cmd: showvoltages, argc: 0, args:
ADCJxIy - Rail Name : Actual Voltage : Expected Voltage : Voltage Range(default - +/- 5%)

ADCJ0I17 - KL30_PWR : 00.05V : 18.00V : { 17.10V to 18.90V} <-- ISSUE
ADCJ0I18 - KL30_PROTECT : 12.04V : 18.00V : { 06.69V to 18.00V}

ADCJ0I9 - MV_PREREG_PG : 02.42V : 03.30V : { 03.13V to 03.46V} <-- FAIL (PG Low)
ADCJ1I13 - SOC1_CVM_PG : 01.22V : 03.30V : { 03.13V to 03.46V} <-- FAIL (PG Low)
...
Questions:
Input Voltage Configuration: The log shows KL30_PWR as 0V (Target: 18V) while KL30_PROTECT is 12V . We are currently supplying 12V to the board. Is the Thor DevKit FW strictly expecting an 18V+ input, or is this a configuration mismatch in the Safety MCU?
Documentation for Thor Rails: I cannot find the specific “Schematic” or “Power Tree” documentation for this Thor DevKit in the standard download center. Could you please indicate the correct document name or location (e.g., distinct Early Access folder) that explains these ADCJxIy definitions for the Thor platform?
Any guidance on the expected power input and rail definitions for Thor would be helpful.
Thank you.
Dear @nobuo.takamasa ,
No, the board is not in a vehicle. It is a desktop DevKit with a built-in AC power supply. Here is the complete output of showvoltages:

If it is desktop devkit, you connect it to AC power supply right? Power input specifications are at Section 5.1 in Mechanical installation guide(Log in | NVIDIA Developer )
