Floating Point Exception(core dumped)

I’m trying to upload firmware to Odroid XU4, SmartPower 2.
I made a change to increase logging frequency of power consumption data.
The code for firmware was taken from here: GitHub - hardkernel/smartpower2
These two commands run fine(with some warnings about some enumeration value and unused variables):

sudo platformio run
sudo platformio run --target upload

when I run the following command, I’m getting the shown error:

sudo platformio run --target uploadfs

Building SPIFFS image from 'data' directory to .pioenvs/esp12e/spiffs.bin
Floating point exception (core dumped)

Can someone help me out with this? There’s another issue like this but that issue doesn’t really address the problem plus the error code is different.
Thanks
