Part Number: CC2640R2F

I am trying to load the example code (ti\simplelink_cc2640r2_sdk_2_30_00_28\examples\rtos\CC2640R2_LAUNCHXL\drivers\empty) at 0x1000 location in Flash

But if I change the linker command file (CC2640R2_LAUNCHXL_TIRTOS.cmd) of example code (C:\ti\simplelink_cc2640r2_sdk_2_30_00_28\examples\rtos\CC2640R2_LAUNCHXL\drivers\empty) to load the code at 0x1000 in Flash(FLASH (RX) : origin = FLASH_BASE + 0x1000, length = FLASH_SIZE - (2 * 0x1000)), I am getting the following error

tirtos_builds_CC2640R2_LAUNCHXL_release_ccs/Debug/configPkg/linker.cmd", line 699: warning #10096-D: specified address lies outside memory map
error #10264: DEFAULT memory range overlaps existing memory range FLASH
error #10264: DEFAULT memory range overlaps existing memory range SRAM

I checked the line 699 in linker.cmd
.resetVecs: load > 0x0

I want to know
a. What is resetVecs is?
b. How to fix the issue to load the code at 0x1000?

Hi Ajay,

This is the reset vectors which is expected to be located at 0x0 per default. If you want to move the application, you would need to also "inform" the TI-RTOS build about this assumes data to be placed at a particular place (inside the first page).

What is your reason to move the app location?

Hi M-W,

I want a Bootloader at location 0x0000, which will load my application at 0x1000. Hence I want to move app location.
Could you please exactly let me know how and where to inform TI RTOS about this?

Regards,
Ajay

Hi Ajay,

You can read about it here:

dev.ti.com/.../node in the "INTERRUPT VECTOR TABLES" section. I would also recommend you look into the BLE examples and how they configure the kernel in OAD projects.
