ALTERA EPXA1 SDRAM BUG

Started by Ralf May 20, 2005
Hi all,

have everyone experience about a second SDRAM with the Altera
FPGA+HARCORE-CPU EPXA1?
Its is unpossible for me to access the second SDRAM.
I used a modified "Hello World" program from ALTERA, Linux running on the
hardcore CPU and ARMBOOT to address the second SDRAM (Chip-Select SD-CS1)
device. But I always get the content of the first SDRAM (Chip-Select
SD-CS0). Both SDRAM devices shared the address and data signals, but every
device get his own chip_select signal.

I would appreciate any help in solving this problem.

Regards Ralf
