Hi All,

We are trying to upgrade wiced FW through OTA. We are downloading FW file, it is a ota.bin file, it is combined file of DCT,file system, bootloader and application bin files.

Once we burn this file, wiced updating with only application. we see application version change after burn but bootloader varsion is not changing.

we suspect Bootloader is not updating with new FW.

Could please anyone help us understand it.

Thanks,

Basava.

Hello:

bootloader is not included.

The OTA2 Bootloader resides in a write-protected part of the Storage System.

The OTA2 Bootloader is finalized at shipment and is not updated through the product cycle

Hi,

I'm using SDK v6.2 and developing it in custom board.

I have developed the ota_image.bin file. is this file include all  other bin files?  APP0,DCT,FS and application?

is it possible to combine bootloader.bin ?  How we can upgrade bootloader over the air?

Thanks,

Basavanagouda.
