[jojorong]

Hi,

    I can not save parameters into SD in boot in IMX6QSD with bellow SD, but i use the classc 4 SD is ok, any limits with bellow SD or my mistake ?

  TOSHIBA EXCERIA Type Ⅱ SDHC-16G UHS/CL10 R95M W60M

    I want to use speeder SD to start up my image :smileysad:

Hi Jojo, I have a sabresd board here and with mainline u-boot I can save the env to SD without a problem. Is this what you are trying to achieve ?

As Vladan notes, the ERROR in your post above is not related to saving env to SD.

This issue is fixed by yocto branch dora duto my testing :smileyhappy:

[VladanJovanovic]

Try inserting the SD card to the other SD slot and boot from it (you will have to change boot device in boot switches in SW6 as well).

You're probably booting from MMC 0 or 2 (don't remember right now how u-boot numers them), and u-boot is trying to save to MMC 1.

Hi,

Can you save parameters to SD card?

For new issue please open a new topic and close this one if solved.

In general, you can see in what step u-boot is failing, so please check if that file is available in your TFTP server's location. Unless you're using mainline kernel with device tree support, you'll probably just want to load uImage directly. follow instructions in Linux User Guide (check documentation package for Linux) to see how to load system via TFTP/NFS.

Hi,

     I switch to SD2 to boot up, but it's failed as bellow, it's the same problems with SD3

Are you able to write anything with mmc write to that device ?
