My Panda ES works with omap2plus_defconfig, but I just noticed that the in-kernel uImage target will use a bad load/entry address so loading and booting that uImage will hang u-boot: Image Name: Linux-3.8.0-rc5-00389-g120d4a8 Created: Wed Jan 30 18:30:39 2013 Image Type: ARM Linux Kernel Image (uncompressed) Data Size: 3843912 Bytes = 3753.82 kB = 3.67 MB Load Address: fffffff2 Entry Point: fffffff2 Looking at the latest build and boot log for SDP (oldconfig) on your build status site verifies that you hit that case too. :( Wrapping by hand (which my scripts already do) produces a bootable image; just verified both with and without device-tree on my panda. git bisect points at a069486162a59513053cf772515217ca61727704 (ARM: OMAP2+: Enable ARCH_MULTIPLATFORM support) Hmm. This happens because nothing sources arch/arm/mach-*/Makefile.boot for CONFIG_ARCH_MULTIPLATFORM builds, even if only a single platform is enabled, since $MACHINE is empty. It seems like most of the available options to deal with this are bad. One thing we should never do though, is to pretend to make a working uImage when we're not. Maybe abort building just like in the case of multiple load addresses? diff --git a/arch/arm/boot/Makefile b/arch/arm/boot/Makefile index abfce28..71768b8 100644 --- a/arch/arm/boot/Makefile +++ b/arch/arm/boot/Makefile @@ -68,8 +68,8 @@ else endif check_for_multiple_loadaddr = \ -if [ $(words $(UIMAGE_LOADADDR)) -gt 1 ]; then \ - echo 'multiple load addresses: $(UIMAGE_LOADADDR)'; \ +if [ $(words $(UIMAGE_LOADADDR)) -ne 1 ]; then \ + echo 'multiple (or no) load addresses: $(UIMAGE_LOADADDR)'; \ echo 'This is incompatible with uImages'; \ echo 'Specify LOADADDR on the commandline to build an uImage'; \ false; \ -Olof -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
