Hi,
My colleague Breno reported an issue with vf610twr_defconfig in U-Boot mainline.
Sometimes it fails like this:
CAT u-boot-dtb.bin COPY u-boot.dtb COPY u-boot.bin CFGS board/freescale/vf610twr/imximage.cfg.cfgtmp CFGS board/freescale/vf610twr/imximage.cfg.cfgtmp MKIMAGE u-boot-dtb.imx Error: No BOOT_FROM tag in board/freescale/vf610twr/imximage.cfg.cfgtmp arch/arm/mach-imx/Makefile:100: recipe for target 'u-boot-dtb.imx' failed make[1]: *** [u-boot-dtb.imx] Error 1 Makefile:911: recipe for target 'u-boot-dtb.imx' failed make: *** [u-boot-dtb.imx] Error 2 make: *** Waiting for unfinished jobs.... MKIMAGE u-boot.imx rm u-boot.imx
After this fails, if I run 'make -j4' then the build successfully completes in the second attempt.
I am able to reproduce it (not 100% though) with these steps:
make mrproper make vf610twr_defconfig make -j4
If I use just 'make' to build with a single core I never see the failure.
Recently Thomas also reported the same problem in the Buildroot autobuilder : http://lists.busybox.net/pipermail/buildroot/2018-March/215036.html
Does anyone have any idea on how to properly fix this issue?
Thanks,
Fabio Estevam
