EMC flash memory programming

2005-08-04 by catstransport

Hi all,

I had in the pass several problems with this board they are all almost
solved. We use now the Philips sc16c754b instead of the Texas
Instruments ti16c754b. Now I do not have to hack into the quaduart
before i write someting. Now is the next problem.

I am a newby in writing to external memory. The RAM works. I can write
to it. But the flash is a problem. We have combined two 16bit flash to
the lpc2292. I have found flash drivers for the 16bit. But I have to
write with 32bit. I just don't know how to get it work.

the memory is: 2 x m29w320DB on bcfg0. bcfg0 = 0x2000348f. After I
write 0x00AA0AA to flashBase[0x05550555] the whole microcontroller
doesn't do anything anymore. Can somebody help me with this problem.

m.v.g.
