Where does uboot store the environment variables? I have my tx25 board booting correctly from uboot when entering interactive commands:

But when I call 'saveenv' then it doesn't boot any longer; it seems that 'saveenv' overwrites parts of the root file system. So, my question is: where does uboot save the environment? -- Thanks, Thomas _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
