Hi Tinu,

How UART mode booting working ...??

Please refer the TI wiki.

IN UART boot mode, UART act as host and it will run the bootloader or app from UART peripheral.

./slh_OMAP-L138.exe -waitForDevice OMAPL138-ARM-LED-uart.bin

suppose my UBL get erased from the flash how the loading of application happening..???

If UBL/u-boot erased, We can't do anything but if any ECC errors happens, software will correct the errors and run continuously.

Nowadays, We don't want UBL and all, we can boot the board in single file through AIS signed u-boot..
