I need the exact Flash layout for On-chip OAD. Especially in ble_simple.. onchip persistent_app, (IMAGE_A)

ccs_linker_defines_tgt.cmd file seems to say FLASH_START = 0xe000,

--define=OAD_TGT_RAM0_START=0x20001000
--define=OAD_TGT_FLASH_START=0xe000
--define=OAD_TGT_ENTRY_ADDR=0x55fc0

Since my app size is larger than 0xe000, That address doesn't make sense.

In Searing my project, I found another code snippet in ble_debug.cfg

m3Hwi.resetVectorAddress = 0x00055fc0;
ROM.constStructAddr = 0x37000;
ROM.externFuncStructAddr = 0x373C0;

If Image_A has start-address 0x37000, All would make sense.

Please help me to understand bellow

OAD_TGT_FLASH_START=0xe000

ROM.constStructAddr = 0x37000;
ROM.externFuncStructAddr = 0x373C0;

Thansk,

Hi Severin,

Thanks your comment. I understood this layout concept. However I can't match this concept to my real project.

I want to know how to decide OAD_IMG_A(HDR_START) Address and the exact value.

Could you explain these values presented my asking?

<ible_debug.cfg>

m3Hwi.resetVectorAddress = 0x00055fc0;
ROM.constStructAddr = 0x37000;
ROM.externFuncStructAddr = 0x373C0;

<ccs_compiler_defines.bcfg>

--define=OAD_TGT_ENTRY_ADDR=0x55fc0
--define=OAD_TGT_FLASH_START=0x36000
--define=OAD_TGT_RAM0_START=0x20001000

Thanks,

dooseok
