Off chip BIM for OAD

Other Parts Discussed in Thread: CC2640, BLE-STACK

Hi,

I am trying to implement BIM for Off chip OAD.

Hardware : CC2640 with Adesto 45DB081E flash.

As per "CC2640 BLE OAD User's Guide.pdf"  there is two configurations available (FlashOnly and FlashOnly_SensorTag)

which configuration should I refer for my implementation ?

What are the differences between these two configurations?

Could you provide your quick suggestions

    Hi,

    As per the document, you should use the FlashOnly build configuration.

    For cross stack compatibility reasons (SensorTag supports other protocols in addition to BLE) the SensorTag project uses a slightly different OAD method than all other BLE-Stack projects. The main differences are highlighted below:

    Internal flash page0 is not protected during SensorTag OAD. It is expected that a SensorTag OAD application include its own reset vectors. This method is risky because if power is lost during page0 programming the device must be recovered using a JTAG debugger. To combat this, all BLE-Stack projects use a "safe" OAD method where page0 and page31 are preserved. (page31 is preserved in the SensorTag project as well, this is where BIM resides).

    Unless there is a specific reason to use the FlashOnly_SensorTag config, then I recommend FlashOnly
