Not quite sure what you want to know !!

I just want to know the version of boot loader & kernel version being used in this image. To get the kernel version, after booting can be obtained in the following way:

Code: Select all

pi@raspberrypi: $ uname -a
Linux raspberrypi 4.4.11-v7+ #888 SMP Mon May 23 20:10:33 BST 2016 armv7l GNU/Linu

I can see that kernel version 4.4.11 is being used in this image.

But I could n't get any command to get the version of boot loader being used here. I thought from boot logs, I can get that version info. But that version is not getting printed even in the console.

Please let me know how do I check the boot loader version being used here

Use
vcgencmd version

BTW, your kernel is more than a year old. The time to update it is NOW!

Yup, it's time to update, as 4.9.xx came stable while ago.

How do I know what is the bootloader version from the above response?
Please let me know

You generally don't need to know what the bootloader version is on the Raspberry Pi. Do you have a specific reason why you need to know this? The advice generally is just keep your system up-to-date using 'sudo apt-get update && sudo apt-get upgrade': this takes care of updating everything, including the binary blob (aka "firmware") which is the closest thing the Pi has to a separate bootloader.

The 'vcgencmd version' command gives you the version of the Broadcom firmware which is present on the SD card which you Pi boots from. Sometimes, when troubleshooting a problem, you may be asked to quote this information. At all other times you don't need to worry about it.

I am using raspberry pi for my application which collects some sensor data and pushes to the cloud. This involves Qt as front end where in which I need to display current boot loader, kernel version along with application version number and other details inside device information page. I badly need to find out the boot loader version number to be displayed on this page. Please let me know to get the boot loader version number

Thanks in advance

I think people are trying to tell you that there is no such thing.

For all practical purposes, the Pi doesn't have a boot loader. Hence, no boot loader version.

I would just use the "version" reported by the 'vcgencmd version' command. Like I said, there isn't really a standalone bootloader on the Raspberry Pi. The closest thing it has is the binary blob that gets loaded at startup, which contains the Broadcom "firmware". The 'vcgencmd version' command returns the version of this firmware.

I take it this is a college assignment?
