Hi,

I want to read the motherboard name for my raspberry pi running raspbian OS?
How to do that ?

Any system commands or C/C++ API's

On other linux machines, I can use the command 'cat /sys/devices/virtual/dmi/id/board_name' to get the board name. But I dont find any DMI data on my Raspberry Pi model B.

Any help is much appreciated.

Thanks
Vipin

There's a few informative and device unique IDs in /proc/cpuinfo. Including a serial number. But I'm not sure if that's what you're wanting information wise. There doesn't seem to be any DMI stuffs in /proc/ or /sys/ on my model B running raspbian. (according to find)

This command requires you to be root to execute.

If your raspbian OS has this command, this will give all info and DMI types on the motherboard.

Here are other keywords to use with dmidecode --type <keyword>

bios
system
baseboard
chassis
processor
memory
cache
connector
slot

Thanks Shadow_7 and Bret for your replies...

@Shadow_7 ... the data in /proc/cpuinfo does not give me the board details... it's only the cpu details I believe

@Bret .. there is no dmidecode or lshw commands in my Raspberry Pi, so any other options..

Or is there any C / C++ Api's to get these details

Thanks

Sorry about that. I did some research and it appears that dmidecode is for x86 CPU's and not for ARM based CPU's.

Got some help from other experts..

In order to get the board name for the Raspberry Pi, we have to first get the Revision number from /etc/cpuinfo and then
map it with the table given in the following wiki..

http://elinux.org/RPi_HardwareHistory

So on my Raspberry board

~# cat /proc/cpuinfo
processor : 0
model name : ARMv6-compatible processor rev 7 (v6l)
Features : swp half thumb fastmult vfp edsp java tls
CPU implementer : 0x41
CPU architecture: 7
CPU variant : 0x0
CPU part : 0xb76
CPU revision : 7

Hardware : BCM2708
Revision : 000e

So checking for '000e' in the table, shows me that my board is B and Pcb revision is 2.0.

Thanks all for your inputs.

I was surprised that dmidecode wasn't ported for the ARM processors. Anyway, I'm glad you got it solved and for sharing the info. Thanks
