Lpc2292 external flash

2005-07-07 by Szemző András

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)
