Dear NXP Engineer,

 

This is Li Zhongyue who is working on imx android solution.

I would like to know how to re-write boot1 partition.

 

Following is my operations, could you help to check if they are correct or not?

1. Erase the block data in boot1 partition first, (API: blk_derase(...))

2. Then write the new data to the same block, (API: blk_dwrite(...))

3. Read the same block, the data is still the old one. (API: blk_dread(...))

And, there are no any errors when i was doing erasing and writing operations. 

 

Or could you give me a guide how to re-write boot1 partition correctly?

 

Thanks a million.

Have a nice day.
