when using a hardfloat toolchain linking u-boot fails.
What version of U-Boot are you building? There's a few rc releases that fail with hardfp-only because a few things leaked in with 64bit math.
Hi Tom,
I also encountered this problem ( http://lists.denx.de/pipermail/u-boot/2015-January/200123.html ) and found it was indeed when 64-bit maths operations were included. To be exact, it was this division of a long long in drivers/video/videomodes.c:
mode->pixclock = 1000000000000LL / EDID_DETAILED_TIMING_PIXEL_CLOCK(*t);
which was part of this commit in Hans' sunxi video series:
0cd5efe videomodes: Add video_edid_dtd_to_ctfb_res_modes helper function
and which was linked into the u-boot binary in a later commit:
e7872f3 sunxi: video: Use video-mode/-timing from videomodes diff --git a/drivers/video/Makefile b/drivers/video/Makefile [...] -obj-$(CONFIG_VIDEO_SUNXI) += sunxi_display.o +obj-$(CONFIG_VIDEO_SUNXI) += sunxi_display.o videomodes.o
Thanks, B.R. Oake.
