LPC288x DCDC LX1 and LX2 values? - bobbruce000 - Jan 23 11:58:36 2007
Howdy,
I am designing a PCB using an LPC2880/2888. I am
trying to setup the DC-to-DC converter. There is
an example schematic in the LPC288x user manual,
but it doesn't specify a value for the coils
connected to DCDC_LX1 and DCDC_LX2. Does anyone
know what the correct values are? Or, even better,
a specific part that is known to work?

i can't use ethernet ram for general purpose - Mehmet Kurnaz - Jan 23 14:33:06 2007
hi all.
i use lpc2368.and i want to use ethernet ram for general purpose too.In sct file i used
RAM2 0x7FE00000 0x00003FFF
{
* (+RW +ZI)
}
So all of data will be in ethernet ram.And i tried a basic application(write to uart). But nothing happend.
Is there anyone who used ethernet ram for general purpose? I wait help.
So thanks..
Mehmet Kurnaz

Hi
You can check for following to use ethernet RAM for general purpose
Enable the Ethernet block by setting the PCENET bit (bit no 30) in the
PCONP register. The Ethernet SRAM is now enabled.
Also refer to ERRATA sheet for LPC23xx
