SUBJECT : How to Set my Own Process Entry Address for U-Boot Application?

We purchased an T4240 EVM Kit for developing, i compiled U-boot application on using below commands.

when we tried to assign our own process entry address, the compiler throws an warning :

#powerpc64-fsl-linux-ld flash.o -o app.o -Ttext=0x01000000

(warning : powerpc64-fsl-linux-ld: warning: cannot find entry symbol _start; defaulting to 0000000001010190 )

Step 1 : powerpc64-fsl-linux-gcc -c flash.c

Step 2 : powerpc64-fsl-linux-ld flash.o -o app.o -Ttext=0x01000000.

(warning : powerpc64-fsl-linux-ld: warning: cannot find entry symbol _start; defaulting to 0000000001010190 )

Step 3 : powerpc64-fsl-linux-objcopy app.o -O binary app.bin.

Help me to sort out this problem ASAP .

Look at documentation for u-boot standalone application:
