is my EZ-KIT SDRAM busted? - Robert K Yu - Aug 1 7:14:00 2003

hi folks, I am playing around with the Bf533 EZ-KIT for the first time, and I'm trying to access the SDRAM. If I read the docs correctly, I ought to be able to point my debugger directly at 0x0000 and access the block of SDRAM. However, I can't modify any of the values there. Is my SDRAM fried?? Another question: where in the debugger do I see the EBIU registers (for the SDRAM interface)?? More symptoms: 1. I take the EZ-KIT out of the plasticwrap and hook it up to my USB port. I install the VisualDSP software. I build & run the LED flash demo. it works. I build & run VisualDSP\Blackfin\EZ-Kits\ADSP-BF533\Examples\MemDMA. it works. 2. I build & run VisualDSP\Blackfin\EZ-Kits\ADSP-BF533\Examples\MemDMA (which populates SDRAM). it hangs VisualDSP, and I have to power cycle the board. 3. Under debugger Settings->Target Options, the "auto configure SDRAM" box *is* checked. thanks -Rob |
