I built u-boot for a 440EPx board derived from the sequoia
configuration.
I am using an FPU-enabled gcc cross compiler.
U-Boot runs fine and successfully boots my operating system (Linux and uClibc-based root filesystem).
However, I was having a problem running busybox that I traced to
errors
occurring executing setjmp, which attempts to save floating point registers.
Then I realized that the FPU was not enabled in the MSR or in the ccr0 register.
Have I misconfigured something, or should I go ahead and add code to
u-
boot to enable the FPU?
Ideally this must be done in kernel somewhere.
Thanks,
Gregg
