Posted on May 17, 2011 at 13:58hi zawada.kris,
i have used FSMC successfully to interface some other ICs but the problem with external RAM is still there. first, the example i mentioned ''
examples\FSMC\
SRAM_DataMemory
'' is not working. i get values
TabAddr = 0xFFFFFFFF
MSPValue = 0xFFFFFFF8
(i have used template project with all necessary steps mentioned in readme.txt)
where as the example ''
examples\FSMC\
SRAM
'' works fine and LED1 gets ON which means Read/Write to External RAM went OK.
Q1) what is wrong with the
SRAM_DataMemory example?
Q2) what is the
difference between these two examples in terms of FSMC initialization for interfacing external RAM.
Q3) what is the difference between ''use Default startup = yes'' and ''Default startup = no''
and similarly what is the difference between Default script file and stm32f10x_flash_extsram.ld
(please help me in understanding these two files ''startup file and script file'' so that i can use them in my projects effectively)
(i am done with rest of the peripherals by using default startup file and script file in project settings and done rest of the settings in main code)
hope to hear from you soon. regards
