overflow interrupt may be lost even if the STM32 is powered down only momentarily.
|
||||
Therefore hi-res solution is only useful in systems where the power is always on.
|
||||
|
||||
FSMC SRAM
|
||||
=========
|
||||
|
||||
The 8-Mbit SRAM is connected to the STM32 at PG10 which will be FSMC_NE3, Bank1
|
||||
SRAM3. This memory will appear at address 0x68000000.
|
||||
|
||||
The on-board SRAM can be configured by setting
|
||||
|
||||
CONFIG_STM32_FSMC=y : Enables the FSMC
|
||||
CONFIG_STM32_FSMC_SRAM=y : Enable external SRAM support
|
||||
CONFIG_HEAP2_BASE=0x68000000 : SRAM will be located at 0x680000000
|
||||
CONFIG_HEAP2_END=(0x68000000+(1*1024*1024)) : The size of the SRAM is 1Mbyte
|
||||
CONFIG_MM_REGIONS=2 : There will be two memory regions
|
||||
: in the heap
