Lpc2000

Hello anyone, or all,

I'm playing with the LPC2294 ARM (from Phillips of course) and dont
seem to be able to write data into the RAM space. A latch is located
at offset 0x60000, on CS3.

Here is what I do (extract from the main routine) :

//    Enable data and address bus, together with Rd, Wr and CS x pins
    __PINSEL2 = 0x0FE169EC;

//    Set CS 3 register of eexternal memory controller
    __EBI_CRS3 = 0x1000FBEF;

// Write Some byte to the address located in CS3 range
    __DigOut = Some byte;


These are defined as :

#define __PINSEL2    *(volatile unsigned long*)(0xE002C014)

#define __EBI_CRS3   *(volatile unsigned long*)(0xFFE0000C)

#define __DigOut *(volatile char*)(0x83060000)


On CS3 I get a nice negative puls, the data is vissible on the data
bus, but the write stays high. Am I missing something obvious.

If someone has a hint, welcome,

Thanks,

Didier
