Hi Toradex,
I expect to flash whole Apalis iMX6 image generated by Buildroot to the eMMC memory. From other threads, I think that using **Toradex Easy Installer** is the most convenient way for flashing new image. With **Open Embedded**, necessary artifacts like **image.json** is automatically generated. In the case of Buildroot, I plan I have to edit this file myself, so I'd like to know if you could give me some instructions for this purpose by modifying existing **image.json** :
{
"config_format": 1,
"autoinstall": false,

},
{
"partition_size_nominal": 512,
"want_maximised": true,
"content": {
"label": "RFS",
"filesystem_type": "ext4",
"mkfs_options": "-E nodiscard",

}
]
},
{
"name": "mmcblk0boot0",
"content": {
"filesystem_type": "raw",
"rawfiles": [

"dd_options": "seek=2"
},
{
"filename": "u-boot.imx",
"dd_options": "seek=138"
}
]
}
}
]
}
With the output folder of Buildroot looks like :
drwxr-xr-x 2 toto toto 4096 Thg 3 25 11:10 ./
drwxrwxr-x 6 toto toto 4096 Thg 5 24 11:53 ../

-rw-r--r-- 1 toto toto 4994576 Thg 3 25 11:10 uImage
Currently, I can flash the Buildroot's image into SD card and make it run from this storage.
Thanks and regards,
Khang
