Summary: appended device tree blobs on uImage fails
Product: buildroot
Version: unspecified
Platform: PC
OS/Version: Linux
Status: NEW
Severity: minor
Priority: P5
Component: Other
AssignedTo: unassigned at buildroot.uclibc.org
ReportedBy: richard.genoud at gmail.com
CC: buildroot at uclibc.org
Estimated Hours: 0.0
The version impacted is 2012.08 (it's not in the list)
the commit 978928e4acb0ee4e335eaf4bf8feca895f372418 adds the ability to append
device tree blobs.
This works great with zImage.
BUT, with uImage there's a problem:
in linux.mk, the line :
cat $(KERNEL_ARCH_PATH)/boot/$(KERNEL_DTS_NAME).dtb >>
$(KERNEL_ARCH_PATH)/boot/zImage
is all right, but after that, the line :
$(TARGET_MAKE_ENV) $(MAKE) $(LINUX_MAKE_FLAGS) -C $(@D) uImage
erases the zImage that has been just done.
that's because in the kernel, the uImage rule is :
$(obj)/uImage: $(obj)/zImage FORCE
@$(check_for_multiple_loadaddr)
$(call if_changed,uimage)
@echo ' Image $@ is ready'
=> so if we do a make uImage, zImage is overwritten.
