Raspberry Pi Compute Module - Getting Started

Hello, to all

As I am new to this, I have just one question, how do I recover my Raspberry Pi Compute Module from a kernel panic; or, do I have to buy a new one, because the one I have is bricked.

I add this comment to respond to Clem Martins' s response to me; it only occurs once, as no OS is loaded, no access to console terminal, can't copy and paste, etc. The only program that I'm aware of is the raspberrypi.org Documentation and WDLabs.com Compute Module and 2.5in SATA-to-Rpi Adapter Board.

I flashed the Raspian image[http://downloads.raspberrypi.org/raspbian_latest] on the emmc using the stated process[https://www.raspberrypi.org/documentation/hardware/computemodule/cm-emmc-flashing.md] and I am able to view /sda1 and /sda2 on my system.

After that I turned off the rpi compute module, changed the jumper position, removed the slave usb, plugged in the HDMI and powered it back on.

However I am getting a series of errors at boot-

No file system could mount root, tried ext4.

kernel panic - not syncing : VFS: Unable to mount root fs on unknown-block(179,2).

...

Kindly help.

When I rote mount I get the following answer:

I does not get any /dev/sdX. Which one of the lines is Compute Module ?

I had some problems installing it and I solved it updating and upgrading ubuntu after:

sudo apt-get install libusb-1.0-0-dev

just add:

sudo apt-get update

sudo apt-get upgrade

Maybe it can be useful to anybody

With the Raspberry Pi Rev 'B' uart is gpio 14, txd, gpio15, rxd and I2C gpio 0, SDA, and gpio 1, SCL. What pins are these on the compute module IO card? And why?
