As you have seen, FS-boot's default behaviour unless you interrupt 
presing 'S' is to jump to the u-boot image in flash.  u-boot itself is 
packaged in a self-relocating payload that copies to RAM then runs.

If you have an old u-boot image in flash (based on the PetaLinux 
reference design), and your new system address map is different 
(DDR/Flash addresses) then this might be causing a problem (the old 
u-boot image still in flash is pointing to bad addresses)

Try using petalinux-jtag-boot to boot u-boot:

petalinux-jtag-boot -i /tftpboot/u-boot.bin -a 0x.....

where the -a param specifies the start address.

Once u-boot is up and running, you can use it to burn itself into flash, 
and boot the kernel etc.

Regards,

John
