I designed STM32F207ZG and I have a external SRAM with 1MBytes.
I used an example in st web-site. (FreeRTOS + lwIP)
From orginal project, I can read/write the external SRAM without runnig FreeRTOS , but I can’t run my FreeRTOS kernel using external SRAM.
I modified scatter file in uVision , but it didn’t work :
========================================================================
; *************************************************************
; *** Scatter-Loading Description File generated by uVision ***
; *************************************************************
LR_IROM1 0x08000000 0x00100000 { ; load region size_region
ER_IROM1 0x08000000 0x00100000 { ; load address = execution address
*.o (RESET, +First)
*(InRoot$$Sections)
.ANY (+RO)
}
RW_RAM1 0x60000000 UNINIT 0x00100000 { ; RW data
heap_2.o(+RW +ZI)
}
RW_IRAM1 0x20000000 0x00020000 {
.ANY (+RW +ZI)
}
}
Do you have any idea to solve this problem?
Please help me…
