# Revision history [back]

Hi There,

Well, I tried this long, confusing, procedure and I was able to get Hydro on my RPi wheezy image. below are the steps I followed: (Please correct me if I did something wrong) 1. Resizing the RPi image, well I used a 16Gb SD-card and was able to expand the file system on my Rpi hardware, using the sudo raspi-config utility. (My Idea was, to boot with as much memory as I could get). 2. Getting the expanded RPi image on to my PC (Ubuntu 14.04). with the command sudo dd if=/dev/sdx/ of=/<path-to-my-image.img> (The Idea again is, not to use RPi hardware to perform source installation--->as it takes very long time) 3. To boot the copied .img file in step 2 with QEMU (ARM Emulator). As mentioned in the previous answer above. (encountered a small problem here with the latest RPi image dated 09-09-2014). But I was able to boot into the RPi desktop. 4. Following the ROS Hydro Source installation.I was able to complete the ROS installation and also could run the roscore on the QEMU terminal. (But with the exception that I was not able to install separate new packages and further steps were unsuccessful). 5. The Last step is to get the image with ROS Hydro back onto the SD-Card with command, sudo dd if=<path-of-the-image-file-with-ros hydro=""> of=/dev/sdx ( step-2 reversed ). And ... I was NOT able to get the image run properly on Rpi hardware.

So, requesting ROS-Pi users who have already done this successfully to shed some light on this procedure, mentioned above. I spent the whole week with the emulation thing and could not get it to run on the actual hardware.

Thanks again,

UPDATE: I am using raspberry Pi B+ Hardware, many old distributions won't even boot on the new hardware. During the boot, I also encountered a problem of "missing kernel (ERROR) modules" with the old dist of wheezy(after performing above steps). Guess, this info might be helpful.

UPDATE:UPDATE 1: I am using raspberry Pi B+ Hardware, many old distributions won't even boot on the new hardware. During the boot, I also encountered a problem of "missing kernel (ERROR) modules" with the old dist of wheezy(after performing above steps). Guess, this info might be helpful.

UPDATE 2: Hydro installation (debian) is available, I am getting dependency error when trying perform this installation. Anyone else who have done this please share your experiences.

rosdep install --from-paths src --ignore-src --rosdistro hydro -y -r --os=debian:wheezy
