Dear all,

I'm trying to increase my RAM memory from 64MB to 128MB.

1)
In the config.bib file I have tried to change the size of the RAM section:
RAM 8026c000 03B94000 RAM
VIDEOMEM 83e00000 00200000 RESERVED

to the new values
RAM 8026c000 07B94000 RAM
VIDEOMEM 87e00000 00200000 RESERVED

(changing the address of the video buffer in the lcdc.reg file)

2) in the cfg.inc file I have changed the RAM size
old:
DCD AT91SAM9263EK_VA_BASE_SDRAM, AT91SAM9263EK_BASE_SDRAM, 64 ; AT91SAM9263EK SDRAM (64MB).
new:
DCD AT91SAM9263EK_VA_BASE_SDRAM, AT91SAM9263EK_BASE_SDRAM, 128 ; AT91SAM9263EK SDRAM (128MB).

I have compiled correctly the new BSP, but when trying to downlaod it with the PB into the board I get a fault error

are the above steps correct?

Is something else to change?

thanks

sorry I'm working with WINCE 6.0

Hi,

Your settings seems good for WinCE, but have you changed the settings of the SDRAM controller (%_TARGETPLATROOT%\SRC\BOOTLOADER\FirstBoot\sdram.c in the AT91F_InitSdram() function) ? After, you must program firstboot and eboot.
If you encounter always errors while booting, you can implement a SDRAM test just after having initialized the controller in firstboot by writing/reading pattern in all the SDRAM and displaying result in the debug port. Perhaps you should also refresh sometime the watchdog in your SDRAM test loops (~ pWDT->WDTC_WDCR = AT91C_WDTC_WDRSTT | (0xA5 << 24);)

hello Adeneo,

You are right! I have setted correctly the SDRAM controller and now is working.

Is there a way to know exactly the amount of memory recognised by wince. in the control panel->system properties I see in the memory box about 95732 KB RAM, is it OK?

many thanks

Hi,

You are right, control panel->system properties are good solution to know the amount of RAM.

I tried to make changes to increase the memory to 128MB but when I build the first boot, this has a size greater than 4Kbyte.

In particular the size on disk of "firstboot.bin" are 4096 but when I convert it into .nb0 file (I used cvrtbin) the size is 8304 byte

Any suggestions?

Hi tecnors,

Are you generating Firstboot in release mode, because you mustn't compile it in debug mode?

Hi, We are having problems making 128Mb available to Android/Linux. Do we have to change the Controller settings for this. Can you let me have an example of what they are and possibly how to do it for Linux.

Thanks very much!

Got this from Ronetix :-

edit include/configs/pm9263.h and change on line 98 from
"AT91_SDRAMC_NC_9" to "AT91_SDRAMC_NC_10", and also the line 224 from
"#define PHYS_SDRAM_SIZE 0x04000000" to "#define
PHYS_SDRAM_SIZE 0x08000000"

Hi warrell,

I think your are not on the right forum. This is a WinCE forum...
