Subject: [U-Boot-Users] U-Boot with gcc-3.3.2 and ARM926EJS Targets fails due to __udiv0
Date: Tue, 27 Jan 2004 15:24:33 +0100 [thread overview]
Message-ID: <200401271524.33646.maillist@fsforth.de> (raw)
Hi folks,
I'm currently porting U-Boot 1.0.0 to a NetSilicon NS9750 (ARM926EJS core).
This port is partly derived from board/omap1610inn. The compiler is
gcc-3.3.2, taken from the uClibc toolchain.
For my target the compiler is using his internal libgcc.a:__div0 routine which
of course fails (it's an SWI instruction). But compiling U-Boot for an
smdk2410 platform with the same compiler uses the correct U-Boot's own __div0
code. I can't see any relevant differences in both build lines.
Can anyone help me? And is it really necessary to include libgcc.a?
The build line for the NS9750:
