Reference Page for U-boot Env Vars & Values
Please add only stock or standard values from a U-boot version supplied by Buffalo or by a developer associated w/ the Wiki, and no custom values, except in the place at the end. Please list:
- source of U-boot (Buffalo, wiki, foonas)
- the version
- the date of build and
- all stock/standard env vars.
The version and date can be found in U-boot's boot messages via netcat or a serial terminal (if you have fitted a cable to your box's Serial_port). The values can be found by issuing the command "printenv" while in U-boot, or the command "nvram -c printenv" whilst in EM etc. It is also possible using the fw_printenv command available as part of the uboot-envtools package in Debian (assuming you haven't changed the default uboot environment of course).

Restoring Default Values to U-Boot Env Vars
Use at your own risk. Erasing in U-Boot can be potentially disasterous. Make sure you research your board before proceeding.
The values shown below are for a custom build of UBoot for an LSPro that uses the standard address and size. If you want to restore the values that were specified at build time for UBoot, you can do it with these steps:
- research (in UBoot sources, see the include/configs/<boardname-or-linkstation-name>.h) to see where the environment variables are and the size of the sector(s) for them, then compute the begin and the end, as in feroceon.h :
#define CFG_ENV_ADDR 0xfffff000 #define CFG_ENV_SIZE 0x1000 #define CFG_ENV_SECT_SIZE 0x1000
- For newer versions of the u-boot source, it is more complicated to spot the valies, since there are many '#ifdefs'. Here is a help:
- Identify your Board and determine which config has to be build, e.g. `buffalo_mvlswvl_6282_config` for a LS-WVL)
- Run 'make <your-board>_config'.
- Fix `include/config.mk`:
- One of the lines my start with `-e CPPFLAGS`: remove the `-e ` there.
- If not cross-compiling, set `CROSS_COMPILE =`
- Add this file `xxx.h` to the u-boot source:
#include <config.h> "CFG_ENV_ADDR" CFG_ENV_ADDR "CFG_ENV_SIZE" CFG_ENV_SIZE "CFG_ENV_SECT_SIZE" CFG_ENV_SECT_SIZE "CFG_ENV_OFFSET" CFG_ENV_OFFSET
- Add this lines to the end of the Makefile (mind the Makefile syntax: the second line must star with a tab character):
xxxxxx:
$(CPP) $(CPPFLAGS) xxx.h
- run:
make xxxxxx | tail
- This will give you something like this:
"CFG_ENV_ADDR" ((0xf8000000) + 0x00080000 - 0x10000) "CFG_ENV_SIZE" 0x10000 "CFG_ENV_SECT_SIZE" 0x10000 "CFG_ENV_OFFSET" (0x00080000 - 0x10000)
- compute the begin and end ( get out your "hexadecimal calculator" if your hex math skills are rusty! )
begin = fffff000 end = begin + 1000 = ffffffff
- unprotect, erase and protect
=> protect off fffff000 ffffffff Un-Protected 1 sectors => erase fffff000 ffffffff Erased 1 sectors => protect on fffff000 ffffffff Protected 1 sectors
LSPro
see the example above, but check your uboot source first
LS-HG
Using LNI's setup, it is as follows (check and adjust if you have a custom build)
protect off fff60000 fff6ffff era fff60000 fff6ffff protect on fff60000 fff6ffff
