I am using startkit in building a prototype.
I need to store the readings of some sensors to be made available between restarts/ power ons
Could someone please help me in understanding the possible ways to achieve this?
Is it possible to store data (store sensor readings) on star Topic is solved

Hi,
The startKIT has a SPI flash to store the firmware but it can also be used to store data besides the firmware (it is large enough).
Keep in mind though that flash devices have a limited amount of write/erase cycles.

If i recall correctly you will first need to create a data partition using xflash. See the xflash documentation in the xTIMEComposer userguide.
