Hi,

If you want to convert the u-boot.bin to AIS format then do the following,

Procedure for u-boot building:

make clean ARCH=arm CROSS_COMPILE=arm-arago-linux-gnueabi-

make distclean ARCH=arm CROSS_COMPILE=arm-arago-linux-gnueabi-

make da850_am18xxevm_config ARCH=arm CROSS_COMPILE=arm-arago-linux-gnueabi-

make u-boot.ais ARCH=arm CROSS_COMPILE=arm-arago-linux-gnueabi-

You can convert AIS format directly while compiling u-boot,

"The entry point for the uboot given in PSP release is 0xC10800000."

This is the entry point for SD/MMC Boot, Is this the same for NAND Boot ?

Have a look to my previous reply,

Yes it is.

If you build the u-boot source with AIS format then u-boot source will take care everything but configuration is matters.
