The problem of storing evironments on DM6467

mick14226

I use the DM6467 EVM board. My board cann't store my environment.

I used "setenv bootargs ....", "setenv bootfile ...." and such kind of orders, then saved them with "saveenv". I could use "printenv" and see them. But when I restart my board, the environments would disappear.

I burned the u-boot in mv_4.0.1 again, and the problem is the same.

Is the problem of my hardware or something else?

When you run saveenv do you see any output messages that may indicate failure to actually save the environment variables?

Have you tried a prebuilt U-Boot image from within your DVSDK/PSP, in particular something like dvsdk_1_40_00_21\PSP_01_03_00_070\bin\dm646x\u-boot.bin?

I have tried the u-boot.bin both from the folder of DVSDK and the one compiled by myself. Both of them cann't save the environments

While I used the order "saveenv", nothing wrong came out.

I am thinking about whether there is some problems on my EVM board or not.

Are you by any chance using a different NAND part than what comes with our DM6467 EVM? I have seen this behavior when using a different NAND part and not adjusting u-boot to support this new NAND device.
