Hello Pratik,
please see below another answer from the SW team I have just received.
DESCRIPTION
Please inform us about which version of BMS SDK and RTD drivers are you using.
Please make sure to have all the MCAL-layer drivers initialized prior to Phy_665a initialization: (Icu, Mcu, Mcl, Spi, Gpt, OsIf, Platform, Port, Rm). You can use an Tresos/S32DS example as a reference.
Please make sure you have the interrupts configured as specified in the user manual and that the interrupt controller is initialized and working.
Spi driver shall be configured to work in asynchronous mode.
With Best Regards,
Jozef
