TDA4VM: How to dump on board eMMC RAW image from EVM?

Gibbs Shih

Part Number: TDA4VM

Hi, Experts.

Customer wants to clone on board eMMC software (RAW image), and save this RAW image as file.

They will burning this "RAW image file" into new eMMC chip by burning machine (ex:Elnec programmer, https://www.elnec.com/en/), and then mount to new PCB board in MP stage.

My question is :

Base on software point of view, Do we have any way (sw tools) to dump RAW image from eMMC?

or any example?

Many Thanks

HI Gibbs

If you want to get the raw dump of the emmc boot 0 image either you can use dd command or cat in the linux

example cat /dev/mmcblk0boot0 > temp.img

Flashing the image to the new emmc that part i am not sure , not have tool to test at my end.
