Hi Juergen and Sascha It seems CONFIG_ARCH_AM33XX and CONFIG_ARCH_OMAP are missing in the include/generated/mach-types.h. Could that cause the problem? lewis@lewis-ubuntu:~/OpenProj/barebox$ cat .config | grep ARCH # CONFIG_ARCH_AT91 is not set # CONFIG_ARCH_BCM283X is not set # CONFIG_ARCH_CLPS711X is not set # CONFIG_ARCH_DAVINCI is not set # CONFIG_ARCH_DIGIC is not set # CONFIG_ARCH_EP93XX is not set # CONFIG_ARCH_HIGHBANK is not set # CONFIG_ARCH_IMX is not set # CONFIG_ARCH_MVEBU is not set # CONFIG_ARCH_MXS is not set # CONFIG_ARCH_NETX is not set # CONFIG_ARCH_NOMADIK is not set CONFIG_ARCH_OMAP=y # CONFIG_ARCH_PXA is not set # CONFIG_ARCH_ROCKCHIP is not set # CONFIG_ARCH_SOCFPGA is not set # CONFIG_ARCH_S3C24xx is not set # CONFIG_ARCH_S5PCxx is not set # CONFIG_ARCH_S3C64xx is not set # CONFIG_ARCH_VERSATILE is not set # CONFIG_ARCH_VEXPRESS is not set # CONFIG_ARCH_TEGRA is not set # CONFIG_ARCH_UEMD is not set # CONFIG_ARCH_ZYNQ is not set # CONFIG_ARCH_QEMU is not set CONFIG_ARCH_AM33XX=y CONFIG_DEFCONFIG_LIST="$ARCH_DEFCONFIG" Kind regards, Lewis On Thu, Mar 21, 2019 at 5:25 PM Juergen Borleis <jbe@xxxxxxxxxxxxxx> wrote: > > Hi, > > On Thursday 21 March 2019 08:53:06 Lewis Zhou wrote: > > [...] > > {standard input}: Assembler messages: > > {standard input}:123: Error: selected processor does not support `rev r7,r7' in Thumb mode > > This is an assembler and not a compiler error message. > > jb > -- > Pengutronix e.K. | Juergen Borleis | > Industrial Linux Solutions | http://www.pengutronix.de/ | _______________________________________________ barebox mailing list barebox@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/barebox
