Hi Mika Do,
thanks your wonderful post ,i have build it from you script and its working on a sdcard (i have A20 dev board).
i have two questions 1.)how do i enable ethernet ?, that is  emac module ,is it available over the current kernel or should i build it,
2.)the same  image will work over nand flash
regards
Sijo k

Is this for NAND or for SD card?

[Mika Do]

For nand

[Sanyigz]

But how can i upload it to NAND? Is the nand appear as a drive if i connect the cb2 the pc with the otg port?

[Mika Do]

Once You get  the .img file used  the tool to install  it on the nand 

[Sanyigz]

Can you upload the images to somewhere? As the last five instructions, are unclear, causing a lot of errors, and did not create an img file, but something on the SD card that looks like a cubie2 image.

[Melahat Tunalı Karakaş]

Is an .img file is created as a result of the operations given in the previous e-mail?

Nope, that's the problem, there were a lot of errors.

[Melahat Tunalı Karakaş]

Must the image be created if the errors are overcame? Or just SD card mirror is created without img file?

I could run without any errors, but img file is not created. In SD card there is 2 partitions as it must be with neede files. And in the output directory there is the same structure as SD card, without any img file.

a other way is :

after you build your env abd you get the img file (http://cdimage.ubuntu.com/ubuntu-core/releases/)

is to extract the img file 

run the script $source tools/scripts/envsetup.sh and chose option 1: build CB2

run $cb_build_nand_image, and it will create the .img file 

[Melahat Tunalı Karakaş]

Thank you for your help, i am going to try the suggestions.

[Melahat Tunalı Karakaş]

after doing the instructions step by step, cb_build_nand_image command still does not exist :((

[Melahat Tunalı Karakaş]

hi, i found it in https://github.com/meal/linux-sdk-products.git  and could produce the image file finally, thank you  for your help indeed.

[Mika Do]

[Mika Do]
