Hi,
I just tested myself the following process for the AM437x Starterkit, in order to attempt a QSPI boot. For that I used the latest SDK 2.00.02.11
Going by this
http://processors.wiki.ti.com/index.php/Linux_Core_U-Boot_User%27s_Guide#AM43xx_support
Latitude-E7450:~/ti-processor-sdk-linux-am437x-evm-02.00.02.11/board-support/u-boot-2015.07+gitAUTOINC+46c915c963$ make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- distclean

This results in a u-boot.bin to be flashed into QSPI. Here is the flashing:
U-Boot# tftpboot 82000000 u-boot.bin
link up on port 0, speed 100, full duplex
Using cpsw device
TFTP from server 192.168.1.118; our IP address is 192.168.1.122
Filename 'u-boot.bin'.

Then removed the SDCARD and power cycled the AM437x Starterkit, but nothing is coming out of the console.
What are we missing?
Thanks,
