How to put data in the Flash fixed address when compiling the program? Issue Date：2016-08-29
- In the Keil development environment
Use the following:
const uint32_t Buf[1] __attribute__((at(0x1000))) = {0x12345678};
Write data byte 0x12345678 into the address 0x1000.
-
In the IAR development environment
First, declare the constant SIG, and put the constant content 0x12345678 at the address specified by “Flash_Address”:
/* Declaration of signature. Location of it is specified in scatter file. */
const uint32_t SIG @ "Flash_Address";
/* Definition of SIG signature. */
const uint32_t SIG = 0x12345678;
In the link file(*.scf) declare the address specified by Flash_Address. In the following example, specify
"Flash_Address" as 0x1000:place at address mem:0x1000 {section Flash_Address };
