ULPMark™-CoreMark score

Abhilasha · ‎2025-05-22

We were following the ULPMark™-CoreMark User Guide for getting the ulp mark score but the STM X-NUCLEO-LPM01A is always throwing up some error and the LD2(ErrorLED) turns on causing issues. Also if in the case it runs its always telling “>! Validation failed, too little runtime: 0.014000000000000234” “>! Set iterations above 749999 for Energy run”. Even after using the same parameters its throwing the same error. Also at 1ms the connection is never achieved and fails.

It would be great if you can guide us on this.

What error, exactly?

A complex system that works is invariably found to have evolved from a simple system that worked.
A complex system designed from scratch never works and cannot be patched up to make it work.

so i have been following the guide and in the iotconnect for ulpmark-cm, the errors are being shown on the console as below :
000196.568: Checking results for run 2: Energy
000196.580: Validation: Getting self-reported frequency
000196.591: Validation: Getting session iterations
000196.603: Validation: Run mode
000196.619: Validation: temperature
000196.635: Validation: Compute frequency from ticks
000196.650: Validation: EMON voltage (mV)
000196.659: Validation: DUT Library Name
000196.667: Validation: Library Compiler Name
000196.676: Validation: Library Compiler Flags
000196.689: Validation: Runtime >10s and iterations at least 10
000196.701: >! Validation failed, too little runtime: 0.014000000000000234
000196.713: ystem
000196.722: Checking results for run 3: Energy (3V)

Even if I set the iterations as required the same error is thrown with a bigger no for iterations.

and even in between the running the connection is lost (With red light LD2 on over nucleo-lpm01a board) and keeps skipping the runs telling "another script running already"

Hi @Abhilasha ,

May I know the product for which you are looking for the ULPMark™-CoreMark score?

Hi @Amel NASRI

As mentioned I m using X-NUCLEO-LPM01A

Andrew Neil · ‎2025-05-22

X-NUCLEO-LPM01A is just the device to measure the power - @Amel NASRI was asking what is the thing whose power you are using it to measure?

The CoreMark score applies to the device under test - not to the device used to do the testing (the X-NUCLEO-LPM01A)
