I was testing on EXYNOS5250 using 4.7.3 toolchain. My mistake: while testing this patch, I had disabled CONFIG_TRACE, but CONFIG_TRACE_EARLY was still enabled, hence the error. You may ignore the patch. IMHO, we should define the TRACE related config options only if TRACE is enabled. If that is ok for you, I will submit a patch for that. --- a/include/configs/exynos5250-dt.h +++ b/include/configs/exynos5250-dt.h @@ -45,11 +45,13 @@ /* Allow tracing to be enabled */ #define CONFIG_TRACE +#ifdef CONFIG_TRACE #define CONFIG_CMD_TRACE #define CONFIG_TRACE_BUFFER_SIZE (16 << 20) #define CONFIG_TRACE_EARLY_SIZE (8 << 20) #define CONFIG_TRACE_EARLY #define CONFIG_TRACE_EARLY_ADDR 0x50000000 +#endif > Regards, > Simon > -- Tushar Behera _______________________________________________ U-Boot mailing list [email protected] http://lists.denx.de/mailman/listinfo/u-boot
