I am have not been able to run any application.
Using example code Hello_world.c and further simplifying it to .....
printf("hello world" line only.
results in. It seems to me I have not gotten an interface to Uboot stdio
correct.
Using a BDI 2000 results in a crash as well. The BDI-2000 will not allow
Uboot to "boot" without dropping out into a reset.
Is there an example of BDI-2000 running correctly as Uboot comes up? I am
most uncertain about my tools!
