This is a demo implementation of a Linux command line tool to access
the U-Boot's environment variables.
-In the current version, there is an issue in cross-compilation.
In order to cross-compile fw_printenv, run
- make HOSTCC=<your CC cross-compiler> env
+ make CROSS_COMPILE=<your cross-compiler prefix> env
in the root directory of the U-Boot distribution. For example,
- make HOSTCC=arm-linux-gcc env
+ make CROSS_COMPILE=arm-linux- env
-For the run-time utiltity configuration uncomment the line
+For the run-time utility configuration uncomment the line
#define CONFIG_FILE "/etc/fw_env.config"
in fw_env.h.
#define DEVICE2_ESIZE 0x4000
#define DEVICE2_ENVSECTORS 2
-Un-define HAVE_REDUND, if you want to use the utlities on a system
+Un-define HAVE_REDUND, if you want to use the utilities on a system
that does not have support for redundant environment enabled.
If HAVE_REDUND is undefined, DEVICE2_NAME is ignored,
as is ENV2_SIZE and DEVICE2_ESIZE.
