First I would like to note that Arria 10 GX development kit schematic using MAX1619 IC to read the temperature of the Arria 10 core.
Schematic Connection as folows , The output of the MAX1619 -U46 connected to J24 Connector (I2C interface ) through zero ohm Jumper ,
connected to LTC2977(8-Channel PMBus Power system Manager) (I think to alert or turn off power) and it is also connected to the MAXV 5M2210 (CPLD).
From the schematic understanding I can suggest two options ,
Option 1: You can read the Arria core temperature via Max V using connected bus " MAX5_BEn[3:0],MAX5_OEn,MAX5_CSn ,MAX5_WEn and MAX5_CLK"
Option 2: As you said, you can read using Adrinuo or Raspberry pi connect to the I2C bus in J24.
I referred Schematic (for your reference) : "A10GX_PCIE_E3p1.pdf"
