How to flash BMP partion alone under R28.3.1

I had referenced the topics as follows
Now ,I have generated the bmp.blob file ,i want to find a way to flash the bmp.blob to mmc alone. Instead of writing the whole flash, it will take me hours. It’s a waste of time.


Please check if you can flash the BMP partition directly.

sudo ./ -r -k BMP board_config rootdev

hi, thanks for your reply
When I use the above script, the feedback is: “*** Update [BMP] is not supported. ***”.
Is there any other way?

There is no update from you for a period, assuming this is not an issue any more.
Hence we are closing this topic. If need further support, please open a new one.

Hi pwpost,
