RAM and in-built storage (Internal HDD, CF etc) and external CF?

Harkanwaljeet_S — Tue, 19 Jul 2016 09:38:00 GMT

Hi, The title is self explanatory. I need commands to check the internal storage (hard disk, internal compact flash etc) and external compact flash for all platform running EXOS in order to find out the total size, in-use and available etc.

Thanks

Harkanwal

Please issue "fdisk -l" command after entering debug-mode. To enter debug-mode, you need a debug mode password which you can get it from GTAC. Below is a sample output of it.

* SW1.1 # enable debug-mode

Enter debug mode password:

2. Enter a command "!fdisk -l"

* (debug) SW1.3 # fdisk -l

If you insert additional CF memory into this MSM, then you will see another “Disk /dev/had” in the output (In above example, there is no additional CF memory inserted)

Isn't a "ls" not enough? and a "sh mem" for RAM.

Hi David,
Thanks for the update. But surprisingly, I did not find it any impressive to keep dependency on TAC for these simple things.

I have few commands as below:

1) "show memory", "top" etc commands are there for memory.

2) "show memorycard", i believe, is for the external compact flash. If yes what is the internal-memory storage capacity then (e.g. for BD8806 with MSM48c)

"ls" is showing in 1K-blocks and I am not sure if it is 512-bytes or what?

From the below output of "ls" ; shall I consider that the internal-memory is 8 MB.

Hi Harkanwaljeet,
1) "show memory" shows system memory information in other word, system DRAM. You can see total DRAM and free from the output. In case of MSM128, it has 1G DRAM so:

(debug) BD6.4 # sh memory

System Memory Information
-------------------------
MSM-A Total DRAM (KB): 1048576
MSM-A System (KB): 40152
MSM-A User (KB): 304000
MSM-A Free (KB): 704424
MSM-B Total DRAM (KB): 1048576
MSM-B System (KB): 40152
MSM-B User (KB): 316716
MSM-B Free (KB): 691708

You can see total DRAM as 1GB and Free memory is 704MB.

2) "show memorycard" shows external USB memory (maybe CF card if it was old model). But it seems the output of this command doesn't show the size of external memory.

BD-X8.1 # show memorycard
Memorycard is present in USB-1.

So to see the size, you need to execute "fdisk -l" command in debug-mode as I mentioned.

3) "ls" just shows a portion of "/usr/local/cfg" directory and "ls internal-memory" also shows a portion of "/usr/local/tmp" directory.

16384 6268 10116 38%

1K-blocks Used Available Use%
49038 580 48458 1%

I believe 1K-blocks means 1024. Therefore, I think the size of "ls" is about 16M and "ls internal-memory" is about 50M.
