CC2640R2F: CC2640R2F with OAD

Hi Kane,

Even utilizing the stackLibrary configuration, application/stack code can never reside in page 31 or SNV pages. So you'll effectively have 32 - (1 + snv_pages) of flash available for the application/stack.

With the current framework, you can simply merge the stack hex and app hex files to create a super hex and run that through the oad_image_tool to generate an oad image. It'll be a large image, but it'd work.

Can you post me the full log, with verbose option enabled in IAR? (tools->options->messages all)

Internally, we're currently documenting how to create a FlashROM_StackLibrary_OAD_Offchip configuration - until it's released I'll give you an outline of what needs to be done. Note you'll have to trim to the size of the app/stack if you want to perserve SNV.

1) modification of the linker file to exclude last page.
2) modification of the linker file to leave a gap for metadata
3) Everything else specified in the guide
4) Trim the resulting image to app/stack size (optional)

Regards,
Rebel

Dear Rebel：
Thanks for your respond. Could you tell me when TI could release the FlashROM_StackLibrary_OAD_Offchip project?
It is a very important function for our product, and we must adjust our development plan to suit the FlashROM_StackLibrary_OAD_Offchip version release.
Thanks.

Dear Rebel：
By the way, Is the operating process of OAD for FlashROM_StackLibrary_OAD_Offchip same as FlashROM_OAD_Offchip? If it is,then I will use the process of FlashROM_OAD_Offchip to verify whether it can be achieved.
Thanks~

Hi Rebel,

Sorry if I stole this thread. Do you have an example linker file for CCS? I am currently using multi-role project that use FlashROM_StackLibrary and would like to enable OAD on it.

Danh

Hi,

Just want to give more detail on the setup that I am testing.I am using CC2640R2 LaunchPad dev kit.

1. After installed simplelink_cc2640r2_sdk_1_00_00_22, I imported bim_oad_offchip, multi_role_cc2640r2lp_app and multi_role_cc2640r2lp_stack_library into CCS.

2. I built all three projects (starting with bim_oad_offchip, then multi_role_cc2640r2lp_stack_library and finally multi_role_cc2640r2lp_app) and all three built successfully.

3. Then I flashed multi_role_cc2640r2lp_app.hex under multi_role_cc2640r2lp_app/FlashROM_StackLibrary/ to dev kit. Open up a terminal and see that there are message printed on the terminal.

4. I copied the linker file "cc26xx_app.cmd" to "cc26xx_app_stack_oad.cmd" under the same location (examples\rtos\CC2640R2_LAUNCHXL\blestack\common\cc26xx\ccs) and modifies the project properties to use the new "cc26xx_app_stack_oad.cmd"

Went through multi_role_cc2640r2lp_app's Project Properties -> CCS Build ->ARM Linker -> File Search Path -> "${TI_BLE_SDK_BASE}/examples/rtos/CC2640R2_LAUNCHXL/blestack/common/cc26xx/ccs/cc26xx_app_stack_oad.cmd"

5. Build multi_role_cc2640r2lp_app again and flashed the hex to make sure that no function loss and everything is working.

6. Edit cc26xx_app_stack_oad.cmd file

Add these defines

#define FLASH_OAD_IMG_HDR_SIZE 0x10
#define FLASH_OAD_IMG_START (FLASH_APP_BASE + FLASH_OAD_IMG_HDR_SIZE)
#define FLASH_OAD_IMG_MAX_LEN (FLASH_LEN - (1 * FLASH_PAGE_LEN) - FLASH_OAD_IMG_HDR_SIZE)

In System memory map, modify to below:

#ifdef ICALL_STACK0_START
   //FLASH (RX) : origin = FLASH_APP_BASE, length = ADJ_ICALL_STACK0_START - FLASH_APP_BASE
   FLASH (RX) : origin = FLASH_OAD_IMG_START, length = ADJ_ICALL_STACK0_START - FLASH_OAD_IMG_START
#else // default
   //FLASH (RX) : origin = FLASH_APP_BASE, length = FLASH_LEN - FLASH_PAGE_LEN
   FLASH (RX) : origin = FLASH_OAD_IMG_START, length = FLASH_OAD_IMG_MAX_LEN
#endif

// CCFG Page, contains .ccfg code section and some application code.
//FLASH_LAST_PAGE (RX) : origin = FLASH_LAST_PAGE_START, length = FLASH_PAGE_LEN
IMAGE_HEADER (RX) : origin = FLASH_APP_BASE, length = FLASH_OAD_IMG_HDR_SIZE

In Section allocation in memory, modify to below:

SECTIONS
{
  /* .intvecs : > FLASH_APP_BASE
      .text : >> FLASH | FLASH_LAST_PAGE
      .const : >> FLASH | FLASH_LAST_PAGE
      .constdata : >> FLASH | FLASH_LAST_PAGE
      .rodata : >> FLASH | FLASH_LAST_PAGE
      .cinit : > FLASH | FLASH_LAST_PAGE
      .pinit : >> FLASH | FLASH_LAST_PAGE
      .init_array : >> FLASH | FLASH_LAST_PAGE
      .emb_text : >> FLASH | FLASH_LAST_PAGE
      .ccfg : > FLASH_LAST_PAGE (HIGH)
*/

      .imgHdr : > IMAGE_HEADER
      .intvecs : > FLASH
      .text : > FLASH
      .const : > FLASH
      .constdata : > FLASH
      .rodata : > FLASH
      .cinit : > FLASH
      .pinit : > FLASH
      .init_array : > FLASH
      .emb_text : > FLASH
