Does this also mean we can use fw_setenv and fw_printenv from the Linux user-space? How does one need to format partitions / prepare uSD card for this? Currently I have 4 GPT partitions: - /boot (ext4) - FSBL (raw) - OpenSBI + U-Boot (raw) - rootfs (ext4) david > > Signed-off-by: Bin Meng <bmeng.cn at gmail.com> > --- > > configs/sifive_fu540_defconfig | 2 ++ > include/configs/sifive-fu540.h | 2 ++ > 2 files changed, 4 insertions(+) > > diff --git a/configs/sifive_fu540_defconfig b/configs/sifive_fu540_defconfig > index 7d38ec9..6f9e619 100644 > --- a/configs/sifive_fu540_defconfig > +++ b/configs/sifive_fu540_defconfig > @@ -1,5 +1,6 @@ > CONFIG_RISCV=y > CONFIG_ENV_SIZE=0x20000 > +CONFIG_ENV_OFFSET=0x1000000 > CONFIG_NR_DRAM_BANKS=1 > CONFIG_TARGET_SIFIVE_FU540=y > CONFIG_ARCH_RV64I=y > @@ -11,5 +12,6 @@ CONFIG_DEFAULT_DEVICE_TREE="hifive-unleashed-a00" > CONFIG_DISPLAY_CPUINFO=y > CONFIG_DISPLAY_BOARDINFO=y > CONFIG_OF_SEPARATE=y > +CONFIG_ENV_IS_IN_MMC=y > CONFIG_SYS_RELOC_GD_ENV_ADDR=y > CONFIG_DM_MTD=y > diff --git a/include/configs/sifive-fu540.h b/include/configs/sifive-fu540.h > index 2756ed5..fb829be 100644 > --- a/include/configs/sifive-fu540.h > +++ b/include/configs/sifive-fu540.h > @@ -24,6 +24,8 @@ > > /* Environment options */ > > +#define CONFIG_SYS_MMC_ENV_DEV 0 > + > #define BOOT_TARGET_DEVICES(func) \ > func(MMC, mmc, 0) \ > func(DHCP, dhcp, na) > -- > 2.7.4 >

At present U-Boot environment is not saved so it's a little bit inconvenient if booting kernel via network as each time we need input the network environment variables from U-Boot shell. We already have the MMC support and let's enable saveenv with that.
