Hi Keil.
I have a trouble with using SDRAM. (I'm using STM32F429-DISCO Ev Kit) I read some question and discussion in forum abt this.
I have a project use SDRAM. But it's not working. Hope some one can help me. My Keil4 Project Target Option Setting...
--------------------------------------------------------- Read/Only Memory Areas ROM1 : ROM2 : ROM3 : On-Chip v IROM1 : 0x8000000 0x100000 Startup IROM2 : --------------------------------------------------------- Read/Write Memory Areas v RAM1 : 0xD0000000 0x800000 RAM2 : RAM3 : On-Chip v IRAM1 : 0x20000000 0x30000 v IRAM2 : 0x10000000 0x10000 ---------------------------------------------------------
STM32F42x_System.c #define DATA_IN_ExtSDRAM Enable. [ RAM1 : 0xD0000000 0x800000 ] This Option Disable. Initialize SDRAM OK. SDRAM Read/Write is Very Well. But This Option [ RAM1 : 0xD0000000 0x800000 ] This Option Enable. I Want SDRAM Use .bss .data Section. Initialize SDRAM OK. SDRAM Read/Write is not Working. My Application is HardFault. (JTAG DEBUG Check) Dies before the main function call. I have a project use SDRAM. But it's not working. Hope some one can help me. thanks.
Make sure your initial stack is in regular SRAM
