Hullo all , I have 128K * 16 bit SRAM (IS62WV12816BLL) chip that I want to use with my STM32F207ZG (on PORT207Z waveshare board)through FSMC ... the problem is that i can not write properly to the SRAM , when i write say a word , i find that many addresses are written and only half the word is written correctly ...... i also see the value of the SRAM content changing as im moving to other breakpoints in the debug session , Seems like something is changing the content of the SRAM continuously...... any suggestions ?
Sounds like the timing parameters to access the SRAM, as configured by your program, are incorrect. Check what the data sheet of the SRAM recommends.
Thx Tamir for ur reply ........ and I'm gonna check that . I hope it would work though , but have u done that interface before?
