PBI Command For T2080 I2C EEPROM Boot

Dear All,

 

We are loading RCW from i2c EEPROM.

Please let us know how to add PBI command in RCW to boot from NOR flash.

 

We tried disabling the PBI source in RCW and IFC boot_mode set as NOR flash but log shows boot from NAND.

 

We are getting below u-boot logs:

Please verify our RCW and suggest us.

We are using discrete DDR.

 

Thanks,
