STM32F207 + S25FL128P(SPI Flash) I found a similar demo in folder C:\Keil_v5\ARM\Flash\STM32F10x_M25P64 with this kind of Flash Programming Algorithm, can i flash other files like photo/fpga data( not the code data) into the SPI flash ? how ? thanks
If you add data to the .AXF it will get written. So you can make object files you link into the image.
Thanks for the reply, can you describe in detail? For example, i want to flash a fpga file named ABC.PGA into the SPI-Flash at a fixed offset 0x100000, and the program data still in the internal-flash , can that work?
i modify the scatter file like:
LR_IROM1 0x08000000 0x00040000 { ; Internal-Flash ER_IROM1 0x08000000 0x00040000 { ; *.o (RESET, +First) *(InRoot$$Sections) .ANY (+RO) } RW_IRAM1 0x20000000 0x0001FE00 { ; RW data .ANY (+RW +ZI) } } LR_ROM1 0xC0100000 0x00100000 { ; SPI-Flash ER_ROM1 0xC0100000 0x00100000 { ; ABC.PGA } }
i tried and it didn't work. Looking forward to your reply
Ok, but that's not an "Object File" in the sense the linker can use.
Perhaps you have familiarity with File IO operations, where you can fopen()/fread() the file and convert the binary data into an array in a .C file which you can compile and include that way?
ie
uint8_t pga_data[] = { 0x00,0x01,0x02,0x03, ... };
Ok, i'm sorry to bother u again... Actually, i failed the first step, i can't flash the common program data into the SPI-Flash with the newly created algorithm. I wonder if i miss the Pre-download scripts, i didn't add one, it always prompt: Erase Failed! Error: Flash Download failed - "Cortex-M3"
As to STM32F207, when i use the SPI-Flash Programming Algorithm, how to write the Init File? what commands should be done before the program is flashed? Can u provide something? Thanks so much!
