BBB restarts on running a standalone pgm from UBOOT

Hi all,

I’m using arm-linux-gnueabi toolchain for compiling a simple asm program to send a character over the uart. I’m loading it to the address 0x80200000 via y-modem. The file gets trnaferred succesfully. On “go 0x8020000” I get a data abort error from board and resets. Why is it so?

Regards
