From 0f29a61c5339d667aa9243902fb42fb3033c3253 Mon Sep 17 00:00:00 2001 From: Fabio Berton Date: Mon, 10 Jul 2017 17:04:11 -0300 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 Reviewed-by: Fabio Estevam --- 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 749a9e3bc1..61f0c95d55 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) @@ -140,6 +139,10 @@ func(PXE, pxe, na) \ func(DHCP, dhcp, na) +#define CONFIG_BOOTCOMMAND \ + "run finduuid; " \ + "run distro_bootcmd" + #include #define CONSOLE_STDIN_SETTINGS \ @@ -157,6 +160,7 @@ CONSOLE_ENV_SETTINGS \ MEM_LAYOUT_ENV_SETTINGS \ "fdtfile=" CONFIG_FDTFILE "\0" \ + "finduuid=part uuid mmc 0:1 uuid\0" \ BOOTENV #endif /* __RIOTBOARD_CONFIG_H */ -- 2.39.5
