Subject: [U-Boot] Whose responsibility is it to enable FPU?
Date: Mon, 14 Jun 2010 19:02:25 +0000 [thread overview]
Message-ID: <0016e6480e82187a72048902213a@google.com> (raw)
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?
Thanks,
Gregg
