Hi everybody, Thanks for your help. I finally found why my SDRAMs weren't working properly. My DSP was beeing reset by the supervisor chip when accessing the SDRAMs. So CCS was loosing communication with my DSP. The supervisor chip control the 5V, 3.3V & 1.8 V on the board. When accessing the SDRAM, the 5V contains some glitch +/- 300mV. This chip detect it as power loss, reseting then the DSP. The initial mistake was to place this chip to close to the DSP & SDRAM, while on the DSK it is closer the power supply. Regards, Ludo |
