cc1310: OAD with on-chip flash only

Part Number: CC1310

Hello!

I'm trying to implement OAD on cc1310 without external flash.

SDK v.1.40 has OAD example only for external flash. It has symbol "FEATURE_OADStorage_ONCHIP", but this symbol is not used (then I defined this symbol, example stops working).

1. Can you point me the example for OAD OnChip?

2. Can I have the source of BIM from SDK 1.40 OAD example (SDK contained only compiled .bin file)?

    Hi,

    1. In the next SDK (Q4) the WSN example will showcase OAD for on-chip flash update. We don't have any code showing this today.

    2. I will check with the team.

    There is none. It has been deciced to not support OAD on-chip on 128 KiB devices officially. Considering the following requirements, your application size will be limited to 60 KiB effectively:

    • 4 KiB flash page required for the bootloader
    • 4 KiB flash page required for the CCFG section (always the last bytes at the end of the flash)
    • 120 KiB available for application + image

    There might be still the option to compress the binary image and get some extra space for the application, but I wouldn't rely on that. Experience has shown that TI-RTOS applications with significant functionality + communication stacks grow easily much beyond 64 KiB.

    The bim sources can be found in a separate BLE stack example. However, there should be nothing really BLE-related in there:
