Hi,
I'm using LPC2368 with Ethernet and a SD Card (with original MCI driver from Keil) . The library for the filesystem is using DMA and so Have to use the USB memory.
But in the device parameters , there's only 2 internal memories zones : IRAM1 and IRAM2. by default, on the LPC2368 only the Ethernet memory is defined as IRAM2.
Is it possible to set up an IRAM3 pointing on the USB memory ?
if not the case is it possible to use the RAM<x> definitions ?
Thanks in advance
Hello, I don't know if you can make a third ram area, but you perhaps you can stock some data in there by defining it at that specific place. I think u can use the "__at" word (at least with CARM). http://www.keil.com/support/man/docs/ca/ca_ap_at.htm
I just checked theplace where you can set these IRAM. But Perhaps you can set the address of off-chip RAM. You just have to give the startaddress and the size wich can be found in the user manual. This should have to work, I think.
