Hi Sangly,
Can you please give me your u-boot modified files if any,
I will build it and share the u-boot.ais file for NAND flashing,
I am able to build u-boot source, convert to AIS format and flashing into NAND flash successfully.

Bus width 16 and CS connected with EMA_CSn_3 same as OMAPL138_LCDK kit. All of the connections are same as OMAPL138_LCDK kit.

Your configuration seems good,
How about UBL binary and where it resides?

If you are using OMAPL138 LCDK u-boot source files then NAND default bus width is 16 bit and CS is 3,
Also, UBL is not required and we can boot from u-boot directly from NAND flash,
