WICED Smart Bluetooth

Anonymous
Not applicable

===

SDK: 2.2.1

Tag: 920737.

app: OTA hello-sensor app code.

OTA firmware size ~ 30KB.

===

Description:

Device can not be power-on after OTA reset via android/iOS handset.

Investigation:

Our current WP is default low for read/write when run-time storage and OTA download.

in factory report, we find when we use handset to upgrade firmware, after programming done and
do the system reset; device can not be power-on again. It seems boot area is destroyed for some reason.

- do we need to add more delay between OTA re-program to NV and reset owing to
that programming/erasing is on-going while system do the reset (but is boot-code area updated during that time?)

- is it becoz firmware code near 30K so in SOC lower layer, it didnt check the program addr for the boot area??
