Hi,
First of all thank you so much for this community and its active members. Recently i HAD some problems storing data in external sdram on a custom board based on c6713 old processor. I had a 16-bit SDRAM (MT48LC32M16A2 – 8 Meg x 16 x 4 banks) connected on CE3. After digging deeply into datasheets i found a possible issue of initialization procedure of c6713 emif and mentioned sdram. The init procedure of emif is (from spru266e):
----------------------------------------------------------------------------------------------------------------
while the initialization procedure expected by the SDRAM is:
-----------------------------------------------------------------------------------------------------------------
----------------------------------------------------------------------------------------------------------------------------------------
So obviously I have to implement custom init procedure based on emif-SDRAM commands:
------------------------------------------------------------------------------------------------------------------------------------------
My question is: Is there any way i can send SDRAM commands manually through emif to SDRAM? lets say i need to send MRS command that should produce signals as shown above, how can i do it?
