need help about memory

[Boko]

I think something is not right when I tipe "free" in terminal i get

total used free shared buffers cached
Mem: 13956 13692 264 0 708 3976
-/+ buffers/cache: 9008 4948
Swap: 1052216 10208 1042008

I'm using oleg's 1.9.2.7-10 on wl500gp and installed AsusHead Start II, I think I had more memory is there a chance one of my chip's to be dead or it might be some thing else

Thank's sorry for my English it's not my native

Extend RAM to 32MB
After flashing Oleg's FW on your box, it has by default 16MB RAM, but on the PCB are 32MB. By changing some NVRAM variables you can make the hole 32MB RAM accessable.

Attention! This just works with Premium boxes! Use this section on your own risk! It can damage your box! You shouldn't change the nvram variables with a Premium V2 (V1 too)!!!
Code:


nvram set sdram_init=0x0009
nvram set sdram_ncdl=0
nvram commit
reboot

No I tried that and the problem persists also the speed I get through FTP ans samba is 1.1MB~1.5MB I'm sure it was faster :(

speed depend on connected device, but max is about 3.5MB/s for hardware limitations of the asus.

try post your:

cat /proc/meminfo

it looks like:


total: used: free: shared: buffers: cached:

This is generally misleading statement. So, I advice to the other people who read this to avoid trying such method unless they really have 16Mb RAM on Premium v1. I see that this recommendation is removed from Russian howto as dangerous.

As far as I remember that problem existed in very early samples of premium v1, and was solved very long ago.

So, my question is how old is the device? was it seeing all 32Mb before?

and yes I was using earlier versions of oleg's firmware and it was addressing 32MB of RAM and also the speed trough samba of ftp was faster and I'm using the same laptop earlier I was getting around 3MB/s down. from the box now I only get around 1.5MB/s max.

[gouryella]

everything fine, i have no idea (but im not a guru)
you can try:
save configs and flashfs
factory reset
disconnect from power source for 5 minute
on it and check syslog for memory 32MB
if 16 connect thru telnet and repeat (you risk dead device if some memory is bad)

nvram set sdram_init=0x0009
nvram set sdram_ncdl=0
nvram commit
reboot

what is the result of nvram?

[al37919]

what is the current output of

nvram show | grep sdram

[Boko]

what is the current output of

nvram show | grep sdram

[admin@X-Dream root]$ nvram show | grep sdram
sdram_config=0x0062
sdram_refresh=0x0000
sdram_ncdl=0x00010005
sdram_init=0x0009
size: 13140 bytes (19628 left)

[Boko]

I'll try re flushing the firmware but will I jam my current configuration

[al37919]

it seems that you have really a hardware problem. I'd suggest to try the last thing. Do:

nvram set sdram_ncdl=0
nvram commit
reboot

sdram_ncdl is related to some startup memory timings. If zeroed it will be recalculated on startup. However, I dont' think it will change much.

edit: I see it was already recommended above and probably done...
