RM46L852: I2C communication with INA237

Dear Champs,

My customer connected INA237 to RM46L852 through I2C, but failed to communicate with INA237.

As there is no implementation for I2C communication in below sysconfig generated driver code, 

https://dev.ti.com/sysconfig/index.html?product=ascstudio&module=/ti/sensors/currentsensor/INA237

they implemented it by themselves, but failed to communcate with INA237.

Could you please check below code or share the example for I2C communication with INA237?
