Hi Fred,
Sorry, it's out of WLAN scope.
You may need to query platform team for partition management.

Thanks.

Hi Terrence
We checked the presist file system. The file system shows presist used 108K but we checked the free space only has 788K(We think It should around 4M-108K). Do you know who use the other space in presist?

busybox du -h
48.0K ./qcom/softap
52.0K ./qcom
4.0K ./usf/epos
8.0K ./usf
108.0K .

Hi Fred,
Sorry, I can't guarantee the final size of nv.bin because developing team may change or modify the design.
But, it only take around 30KB so far, and it's much less than size of 4MB.
I think presist partition is really enough for now.

Thanks.

Hi Qualcomm
Is WCNSS_qcom_wlan_nv.bin possible over current presist partition layout in the future? Because we want to decide a fixed presist size for developing and shipping.
As I know, default Qualcomm presist partition size is 4MB.
Sincerely Yours
Fred Yu

Hi Fred,
So far, it's around 30KB.
But, we don't have an accurate number for it,
because developing team may add fields for future design and different build.
And you may also refer to the size of WCNSS_qcom_wlan_nv.bin in your current build.

Thanks for understanding.
