[U-Boot] PXA build failure

[U-Boot] PXA build failure

[Sergey Lapin]

Hi, all!

I am used to build at91 board using Angstrom EABI toolchain (gcc-4.2.4)
without any problems. Now I try to build PXA board and have the
following error on final link stage: (I build master branch)

Board name is pxa255_idp. It seems that only PXA does have these problems,
I have tried some other boards and had no problems, again.

Any ideas?

I've also found that thos error is due to:
cpu/pxa/libpxa.a(interrupts.o): In function `get_ticks':
/home/slapin/u-boot/cpu/pxa/interrupts.c:113: undefined reference to

and were introduced by commit 94a3312920b6f9b5da27309549fb73650718c10a

All the best,

This ius a known issue - all PXA boards don;t build currently with an
EABI conformant tool chain.

Jean-Cristophe said he had some patches queued or planned, which we
are waiting for.

I know as tell you Wolfgang PXA have some issue with the EABI toolchain

You can try the mm branch of the u-boot-arm tree

and the patch reply to this e-mail
