Flash/memory mapping on OAD target

Other Parts Discussed in Thread: BLE-STACK

Hi,

Is it okay to increase flash size of image_A?

When I increase image_A, OAD target works well as usual,

after I try to update firmware, it shows "Device disconnect" on SensorTag app.

Please help me with this problem, thanks.

    Hi Wei,

    Are you using an CC26xx device or a CC2640R2? Which version of the BLE-Stack are you using?

    There are certain memory constraints that you need to follow. They are different for the CC26xx and the CC2640R2. I would recommend that you look over the On-chip OAD section of the TI BLE Software Developer's Guide that came with the SDK you are using.

    Why do you need to increase the size of Image A?

    Hi Rachel,

    I'm using CC2640R2 and implement it on version simplelink_cc2640r2_sdk_1_30_00_25 sdk.
    I've read the OAD guide and it didn't show information about memory increasing/decreasing for image A.
    I tried to change the address limitation and it didn't work.
    And the reason I'd like to increase the size is because I was trying to make image A as an original version of our program,
    so it must contains UART.

    Thanks for your reply.
