Hi Gangadhar,

Which dfu_alt_info setting are you using?
Could you also list the output of dfu-util -l from Linux PC?

Hi Gangadhar,

For eMMC, you need to use dfu_alt_info_emmc.

Hi Vishal,_

Thanks for your reply.

1. We would like to copy bootloader images( tiboot3.bin -> sysfw.itb -> tispl.bin -> u-boot.img), kernel(Image), rootfs(tisdk*.tar.gz) into eMMC using dfu-util.

could you please tell us steps.

Please find the attachments

Hi Vishal,

Thank you for your reply,

We are able to copy bootloader(tiboot3.bin -> sysfw.itb -> tispl.bin -> u-boot.img) images into eMMC via DFU using your commands.

Now we want to copy rootfs into eMMC via DFU.

As per our knowledge we have to create rootfs*.jffs2 image from tisdk-default-image-j7-evm.tar.xz for flashing using DFU command(sudo dfu-util -c 1 -i 0 -a 1 -D <rootfs>).

Could you please tell us how to create *.jffs2 image.

Gangadhar

Hi Vishal,

1.         We are able to copy bootloader(tiboot3.bin -> sysfw.itb -> tispl.bin -> u-boot.img) images into eMMC via DFU using following below commands images was downloaded.

a) sudo dfu-util -c 1 -i 0 -a 2 -D tiboot3.bin

           Now we get back to eMMC dip switch settings, in u-boot prompt  nothing is coming.( u-boot is not booting)

2.  Now u-boot is booting from SDCARD

      Using this command " sudo mkfs.jffs2 -r ./tisdk-default-image-j7-evm -e 512 -o rootfs.jffs2" I have created rootfs.jffs2 image,

      Using this command "sudo dfu-util -c 1 -i 0 -a 1 -D rootfs.jffs2" Image was downloaded.

      Now I am getting error is " Unrecognized file system"

Could you please help me.

Thanks

Gangadhar

Hi Gangadhar,

For #1, are you setting DIP switch for eMMC boot partition?

For #2, I need to check and get back.

Vishal

Hi Gangadhar,

I just tried same steps except rootfs and I see it boot successfully.

Regards,
Vishal

Hi Vishal,

For Question 1:-

         Yes your correct, Now u-boot is booting ( After changing proper dip switch settings for eMMC)

For Question 2: -   Now u-boot is booting from eMMC

        But we are getting below error

        We are creating jffs2 image and flashing using dfu-util   -- > is this correct way?  

Thanks

Gangadhar

Hi Gangadhar,

Can you also update below environment variables to reflect file system on eMMC

=> setenv mmcdev 0

=> setenv bootpart 0:1

=> setenv bootcmd 'run findfdt; setenv mmcdev 0;...........'


Can you try creating ext4 image? I am not sure jffs2 image is correct.

Regards,
Vishal

Hi vishal,

Thanks for your reply.

1. We have created ext4 image using below commands

dd if=/dev/zero of=~/rootfs.ext4 bs=1M count=3072
mkfs.ext4 ~/rootfs.ext4
mount -t ext4 rootfs.ext4 mountpoint/
sudo cp -r tidefautrootfs/* mountpoint/
sudo umount mountpoint/

Hi Gangadhar,

Could you try arago-tiny-image?
Pouyan from your team was able to build arago-tiny-image.
