Hi!
I'm trying to interface the 256K x 16 bit SRAM on Infineon's Starter Kit in 16 bit mux mode with the XC161CJ, with /CS1.
My problem is that A16..A18 address lines do not work. I could not detect the pulses with the scope, and the address bus test function also fails. Though 4 bit segment address (A16..A19) is set in Dave.
My settings:
EBCMOD0 = 0x4034 EBCMOD1 = 0x003F FCONCS1 = 0x0031 TCONCS1 = 0x28A9 ADDRSEL1 = 0x4007
The dip switches:
S101: 0x01 S102: 0xBA S102: 0x00 S104: 0xF0 S105: 0x0F S106: 0x00
The lower 64KB seems to work alright, so I dont think there is a problem with the timing, I just cant reach the higher part of the SRAM. The SRAM is set at 0x400000 in uVision.
Is there anyone who has some suggestion for this problem?
Thanks, David
