Hi every one
Good day!
I have been working to solve my issue for more than 2 weeks,Please Help me!
I am using HVKit (F28027) Motorware->proj_lab03 I attached all API File and header file from C:\ti\C2000Ware_1_00_02_00\libraries\flash_api\f2802x\example_ccsv5\Example_Flash2802x_API.c
But sadly the compiler could not find Flash2802x_Program(a,b,c,d),Flash2802x_Erase(a,b,c,d),etc..
I think I should add some code to 28027F.cmd it that right?
sort of like this
However I could not understand those codes,since they are not a C code!
API load/run symbols:
These symbols are defined by the linker during the link. Refer to the
Flash28_API section in the example .cmd file:
Flash28_API: { Flash28027_API_Library.lib(.econst) Flash28027_API_Library.lib(.text) } LOAD = FLASH, RUN = SARAM, LOAD_START(_Flash28_API_LoadStart), LOAD_END(_Flash28_API_LoadEnd), RUN_START(_Flash28_API_RunStart), PAGE = 0
this is the linker code in proj_lab03->28027F.cmd
MEMORY { PAGE 0: /* Program Memory */ /* Memory (RAM/FLASH/OTP) blocks can be moved to PAGE1 for data allocation */ OTP : origin = 0x3D7800, length = 0x000400 /* on-chip OTP */ CSM_RSVD : origin = 0x3F7F80, length = 0x000076 /* Part of FLASHA.

How to insert this code
Flash28_API: { Flash28027_API_Library.lib(.econst) Flash28027_API_Library.lib(.text) } LOAD = FLASH, RUN = SARAM, LOAD_START(_Flash28_API_LoadStart), LOAD_END(_Flash28_API_LoadEnd), RUN_START(_Flash28_API_RunStart), PAGE = 0
In order to not interfere with other memory map.
Isn't here any other way to initialize Flash functions Look like allocation.
//Hardware Allocated memory for I2C Registers
obj->i2cHandle = I2C_init((void *)I2C_BASE_ADDR,sizeof(I2C_Obj));
Thanks for attention.
Regards .
Dave.
