Other Parts Discussed in Thread: BLE-STACK
Tool/software: TI-RTOS
SDK: simplelink_cc2640r2_sdk_2_30_00_28
My project is based on the example simple_peripheral_oad_offchip ( split image configuration ). In the default configuration, Flash map as follows:
APP: 0x00000 - 0x13FFF
STACK: 0x14000 - 0x1CFFF
SNV: 0x1D000 - 0x1DFFF
BIM: 0x1E000 - 0x1FFFF
The features I need for my application are as follows:
- Device Information service
- User service, 0xFFF0
- OAD service,
- No bluetooth pairing
At present, there is not enough code space for my application, only about 1K of code space in 0x00000 - 0x13FFF is left.
I refer to the suggestion given in the user guide: http://dev.ti.com/tirex/content/simplelink_cc2640r2_sdk_2_40_00_32/docs/blestack/ble_user_guide/html/ble-stack-3.x/creating-a-custom-bluetooth-low-energy-application.html#optimizing-bluetooth-low-energy-flash-and-ram-memory-usage
I think Disalbe SNV and modify the stack library option in build_config.opt is useful to me. I did the following test:
① Disable GAP_BOND_MGR in the build_config.opt → The starting address of STACK is changed from 0x14000 to 0x15000.
② Disable GAP_BOND_MGR and L2CAP_COC_CFG in the build_config.opt → The starting address of STACK is changed from 0x14000 to 0x16000.
③ OSAL_SNV=0 in STACK preprocessor option → build error: "Incompatible NV settings detected. OAD supports 1 NV page"
so, my question is:
1. What effect will ① & ② have on my application?
2. How can I disable the SNV and use the free 4K space for my app code
