From 2b94a1cb2817e25c1b2655b9b4c6564f8e5d1b35 Mon Sep 17 00:00:00 2001 From: Fabio Berton Date: Wed, 19 Oct 2016 11:30:35 -0200 Subject: [PATCH] embestmx6boards: Use PARTUUID to specify the rootfs location Currently the rootfs location is passed via mmcblk number and the problem with this approach is that the mmcblk number for the eMMC changes depending on the kernel version. In order to avoid such issue, use UUID method to specify the rootfs location. Also add CONFIG_BOOTCOMMAND to run finduuid function and distro_bootcmd. This change was made based on U-Boot commit: - ca4f338e2efece5196eb2178e5f7d07be828da6e Signed-off-by: Fabio Berton Signed-off-by: Otavio Salvador --- include/configs/embestmx6boards.h | 6 +++++- 1 file changed, 5 insertions(+), 1 deletion(-) diff --git a/include/configs/embestmx6boards.h b/include/configs/embestmx6boards.h index 48c9e0b3e9..a87a590223 100644 --- a/include/configs/embestmx6boards.h +++ b/include/configs/embestmx6boards.h @@ -15,7 +15,6 @@ #define CONFIG_MXC_UART_BASE UART2_BASE #define CONSOLE_DEV "ttymxc1" -#define CONFIG_MMCROOT "/dev/mmcblk1p2" #define PHYS_SDRAM_SIZE (1u * 1024 * 1024 * 1024) @@ -146,6 +145,10 @@ func(PXE, pxe, na) \ func(DHCP, dhcp, na) +#define CONFIG_BOOTCOMMAND \ + "run finduuid; " \ + "run distro_bootcmd" + #include #define CONSOLE_STDIN_SETTINGS \ @@ -163,6 +166,7 @@ CONSOLE_ENV_SETTINGS \ MEM_LAYOUT_ENV_SETTINGS \ "fdtfile=" CONFIG_FDTFILE "\0" \ + "finduuid=part uuid mmc 0:1 uuid\0" \ BOOTENV #endif /* __RIOTBOARD_CONFIG_H */ -- 2.40.1
