RE: Toolchain issue on LPC3250 (was Re: [Ltib] Building problems)

[Kevin Wells]

Yes, that is a toolchain issue. GCC 4.3.2 seems to have some issues with
segmentation faults when building some packages. The GCC 4.1.2 EABI
toolchain is the way to go and is the preferred toolchain for that device
due to it's VFP and EABI support.

The only caveat is that GCC 4.1.2 won't build u-boot due to some issues
with EABI (libs, u-boot ARM code, ??). I usually build u-boot with
GCC 3.4.5 and then install u-boot on the board. Then switch over to
GCC 4.1.2 and turn off the u-boot build option with ./ltib --config.
Once u-boot is installed on the board, you never need to build it again.
