2009-08-25 03:17:12 SDRAM mem customization in uClinux-dist-2009R1-RC1.tar.bz2
Hari Prasad (INDIA)
Message: 79166
Hi,
In 2007R1 kernel, we have the following option to define the SDRAM memory size:
Symbol: MEM_SIZE [=64]
x Prompt: SDRAM Memory Size in MBytes
x Defined at arch/blackfin/Kconfig:271
x Location:
x -> Blackfin Processor Options
x -> Board customizations
In 2009R1-RC1, how can we customize the RAM memory size similarly?
Kindly clarify.

there is no need to as the kernel handles it dynamically

Hi Mike,
We are currently working on a h/w that has 128MB RAM but in future this will become 64MB. So we want to expose only 64MB to the kernel now itself to avoid surprises in future. We also tried out the following command given in the link "https://docs.blackfin.uclinux.org/doku.php?id=linux-kernel:memory_allocation&s[]=memory&s[]=management#silly_nommu_memory_tricks"
bfin> set bootargs root=/dev/mtdblock0 rw mem=64M max_mem=128M$#
However, even after executing the above command, the kernel bootup showed the following:
Board Memory: 128MB
Kernel Managed Memory: 128MB
Kindly clarify the following:
1. Are we missing anything for the 'set bootargs....' not to work?
2. What are the methods available to expose only 64MB to kernel?

Hi Mike,
To add to the above query, we also tried changing the kernel boot address. When tried to set the kernel boot address as 64MB we got the below compilation error
"The kernel load address is too high; keep it below 10meg for safety"
Since we had enough memory we commented out the #error line in the file "linux-2.6.x/arch/blackfin/mach-common/arch_checks.c"
On further compilation after a make clean we got the below errors

The archchecks are not there for fun - they are they so you don't run into problems.
If you go changing random things in the kernel that you don't understand - your system will not work properly. That is what you are experiencing. Revert all your changes, and things will start working for you.

the fact that your /proc/cmdline doesnt reflect your bootargs makes the answer obvious. either you are doing something in u-boot to reset bootargs or you hardcoded the command line in your kernel config.

Hi,
To add with , we tried customizing command line arguments though makemenu config changes as below,
Blackfin Processor Options --->
Board customizations --->
[*] Default bootloader kernel arguments
(console=ttyBF1,57600,mem=32M) Initial kernel command string
Now we got the new parameter displayed as cmdline string, but there is no impact on the SDRAM size,
We got the below responses,

Kindly clarify the following:

2. If so ,are we missing anything else.?

We have also tried modifying SDRAM Bank Control Register with External bank size (EBSZ) bits set to 001 by changing the value of EBIU_SDBCTL Macro in linux-2.6.x/arch/blackfin/mach-bf527/include/mach/defBF52x_base.h
#define EBIU_SDBCTL 0xFFC00A12 /* SDRAM Bank Control Register*/
Initially it was configured as below,
#define EBIU_SDBCTL 0xFFC00A14 /*original Value*/
But with the above change , Kernel is not booting up .
Below were its boot up logs,

either you use the kernel config option or you do it dynamically. your choice, but they end up with exactly the same result.

if you go screwing with the MMRs, then it's your problem to figure out what you did wrong
