hai friends, my name is vishnu. i have been working with C5502 for some time for my current project. coding is done in CCS2. in our DSP board an SDRAM is also connected. i have to configure the SDRAM. i have tried so many ways but i am not able configure the SDRAM correctly. the sdram used is MT48LC2M32B2.. it is a 512K*32*4 bank SDRAM. I have been using csl library.. but i am no...

Hello all, I'm looking to interface SDRAM to the 5502. I've been designing embedded systems for 25 years, but unfortunately (or perhaps, fortunately :)) have never used any type of DRAM. My question is this: Is it possible to manually "bank" SDRAM devices like you can with SRAMs? The 5502 EMIF spec (spru621f) states that 256-Mbit is the largest device that can be used. Can I use, say, ...

All, I'm working with Alex on this project. We've initilized the SDRAM registers according to the datasheet and to reference designs, and still nothing. What seems to happen is if you write a value to odd memory locations, the value sticks and you can read it back. But, ALL odd memory locations show the same value. This is with the chip in CE1 (which does seem to drop). The chip
