Hi all.
I want to use ethernet and usb ram for general purpose sram.I won't use
ethernet and usb only need ram.How do I modoify scatter file?How can i use these
rams?
So Thanks

Hello Mehmet,
To access the RAM you need to set the bit in the PCONP register.

Peter

If you just put data into this SRAM it should work after enabling the
Ethernet block. Check the Errata Sheet, there is no option to execute
code from this particular SRAM.

you need also change your linker for it.

Yes i read errata and i did it.In main i firstly made PCONP |= 0x40000000; for
enabling the ethernet.But nothing become.
Nader wrote that i need chance linker.In linker dialog i didn't choose "Use Memory Layout from target dialog" So i use scatter file.And from 4 subcheckbox i only choosed "Report 'maight fail' Conditions as Errors".Must i choose "Make R/W Section Positions Independent"?Also i tried this but it didn't be useful.
I use usbram witout any problem.But it is only 8k and i need 16k of ethernet too.
So thanks

Hi again.
I can use ethernet ram but there is still some problem.I can't use ethernetRam for some object files.
interrupt.o
serialport.o
libspace.o
lpc2300.o (stack and heap)
interrupt.o makes interrupt enable,open, clear and release.
serialport.o writes and reads uarts
the others are for system.
If i load these files to mainRam or usbRam there is no problem.I think on ethernetRam interrupts can't execute, but timer interrupt executes(i loaded isr of timer to ethernet ram there is no problem).Is there any difference between uart interrupt and timer interrupt?
Is there any restrict for ethernetRam about interrupts?
I need help.
So thanks

HI,
I have Set the PCONP to access Ethernet RAM. This is the first istruction of
my main program.
I'm using a scatter file for a complex memory map. So I have create a
section in the Ethernet RAM in order to put some of my data there.
In details, i have put all my +RW-DATA, +RO-DATA, +ZI of any my module
there.
At the fistt time all worked fine, but i have noticed that any time i add a
module there is some chances of failure.
Where is the mistake?

Read the errata for the chip. You cannot execute code from ethernet ram,
you can only store data there.

hi Baldur
Firstly so thanks for your answer.
You said that cannot execute code from ethernet but code(RO) is in flash.Also timer codes (RW) and a few codes(RW) are in ethernetRam and they execute without problem.my sct file is below
LR_IROM1 0x00000000 0x00080000 { ; load region
ER_IROM1 0x00000000
{ ; load address = execution address
*.o (RESET, +First)
* (+RO)
}
; RW_IRAM1 0x40000000 0x00008000
; { ; RW data mainRam
; * (+RW +ZI)
; }
RW_IRAM2 0x7FE00000 0x00003FFF
{
; * (+RW +ZI)
; serialport.o (+RW +ZI)
; interrupt.o (+RW +ZI)
clock-arch.o (+RW +ZI)
deneme.o (+RW +ZI)
}
RW_IRAM3 0x7FD00000 0x00001FFF
{
* (+RW +ZI)
}
}
As you see clock-arch.o(timers codes) and deneme.o are in ethernetRam and others(uarts codes...) are in usbRam.Application with this sct file runs without problem.
So thanks
