BQ27532-G1: Data flash, how to "IT Enable = 00"

Hello Adrian,

BQ27532-G1 does not rotate IT Enable by simply sending Control(IT_ENABLE), right?

I did a Learning cycle according to SLUA903, 3.2.1 ~ 3.2.6.

Update Status 0 reached 02, so I believe the learning cycle is complete. However, after 3.2.1, IT Enable always remained at 01. (I understand that GAUGE_EN = IT Enable because this document uses Packside as an example to explain the procedure.)

Hello Hitoshi,

I believe it should rotate the bit on this gauge.

Hello Adrian,

I just tested Control(IT_ENABLE) again.

IT Enable is...
00=>01 Yes. the value has changed.
01=>00 No. No, the value does not change.

Is the content of SLUUB04 6.9.2.3.4 incorrect and do I need to edit it directly in BQSTUDIO?

Hitoshi

Hello Hitoshi,

Yes, if possible, see if you can manually edit that value in BQStudio.

Hello Adrian,

OK. Thanks.

I am relieved to confirm that the contents of SLUUB04 6.9.2.3.4 are incorrect.
IT Enable=1, Update Status 0=02 are correct at the time of Golden Image extraction.

I am currently working in Unsealed mode, so editing using BQStudio is possible.

Hello Hitoshi,

Sounds good. Let me know if you have any further questions,

Hello Adrian,

Thanks. Let me check one last thing.
Should the following flag settings be used in the production version for end users?

IT Enable = 0
Update Status 0 = 02

Regards,
Hitoshi

Hello Adrian,

However, it is difficult for end users to perform the following operations:

1. SEALED to UNSEALED
2. IT Enable = 1
3. UNSEALED to SEALED

Therefore, I will provide a golden image to end users with the following settings:

IT Enable = 1
Update Status 0 = 02
Cycle Count 0 = 0

Is this method okay?

Hitoshi

Hello Hitoshi,

Yes, this method will be okay.

Adrian
