Hi, I'd build my own board with 4MB ext. SRAM and 4MB flash. The flash is at49bv320c. I've try the olimex test program, SRAM test is fine,(after some waitstate tuning:), but flash test is fail. I know that olimex using INTEL flash with other ID, but I can't read the ID either. It's a 16bit flash, so I connect OE,WE,CS0, lpc-A1 to at49-A0 and so on... I think it must be good. In my program I setup BCFG0 wait states to max, PINSEL2 is configured to external bus(SRAM is working), A1 line configured to A1, but no success. :( Any idea what may be the problem? (I have try it with 2 flash, 2 board) Or any other test code, or sure working code for the flash? (Sorry for bad English) Andra
