I'm working on imx6q Android 7.1.2 platform. On by board have 4GB internal emmc. so in "device-partitions.bpt" file size i have changed to 4GB.
"disk_size": "4 GiB",
As per your procedure I followed to flash the Android images by using MFG tool. But it stopped at "Formatting cache partition" level.
I have attached MFG logs with this post.
Can you please provide solutions for this as soon as possible.
