Subject: [U-Boot] u-boot on raspberry pi with fw_printenv/fw_setenv
Date: Tue, 6 Jan 2015 13:08:48 +0100 [thread overview]
Message-ID: <20150106120848.GH5040@waldemar-brodkorb.de> (raw)
Hi Developers,
I am looking for a way to change u-boot environment from Linux
on a Raspberry PI. I have fw_printenv/fw_setenv, but I have no clue
how the config file looks like, when using uboot.env as a file on
the first vfat partition. I am not sure, but it looks like there
is no code to use fw_printenv/fw_setenv with files.
rpi.h from git sets:
#define CONFIG_ENV_SIZE SZ_16K
#define CONFIG_ENV_IS_IN_FAT
#define FAT_ENV_INTERFACE "mmc"
#define FAT_ENV_DEVICE_AND_PART "0:1"
#define FAT_ENV_FILE "uboot.env"
This works fine when I use savenv inside of u-boot shell.
What do I miss?
best regards
Waldemar
