Hi.

I assembled bq40z50-R1 on my board.

But I want to use R2.

So, first I programmed R2(bq40z50R2_v2_11_build_52.srec) in bq40z50-R1(on my board).

And I did calibration and Srecord programming using bqproductions.

But bqproduction show the error message. : "MAC command sent does not match MAC returned in read packet."

What is the problem and how to fix it?

Hi, Kim

This is a bqProduction question, I will need to check with the internal team or direct you to the appropriate guy for bqProduction support

I checked this issue and I found one thing.

My bq setting is automatically sealing after the firmware program. It is assumed that this creates a problem.
Teach me how to get rid of automatic sealing.
I will attach my .sec file. Plz check.

Hi, Kim

This is because that the srec file you used for FW programming is extracted from the device which had ever been sealed and then unsealed before. Please try to extract the srec file from a device with its FW had never be sealed
