Raspberry Pi Configuration
Process for configuring a Raspberry Pi for eVOLVER
Please see the Raspberry Pi infrastructure page for additional information on the RPi we use for the eVOLVER.
Be sure to update the server code on the RPi after following this guide, or you will have issues communicating with the server through the DPU or with actuating/sensing connected components!
3. Plug an 8GB micro-SD for the RPi into an adapter, then into a the computer.
4. Click the
Choose OS button, then scroll to the bottom and click Use Custom.
5. In the popup at the dropdown at the bottom of the window, select
All files(*.*). Then select the image file downloaded in Step 1.
6. Click the
Choose Storage button and select the SD Card.
7. Click the
Write button. A notification might appear warning about erasing all existing data on the card. Click Yes. If it asks for your computer password afterwards, enter it. It might take a while to finish (~40m). 8. When it completes, you can plug the SD card into the RPi. You will need to update the server code and potentially the
conf.yml with the latest code from GitHub. 2. Plug the SD card into the computer.
4. Run the following command:
diskutil listIdentify the SD card name from this (it should be obvious). Next run:
diskutil unmountdisk <diskname>where <diskname> is the name you identified from the previous command - it should look like
/dev/disk3/ or something similar.5. Use the
dd command to copy the image onto the SD card:sudo dd bs=4m if=<diskimage.img> of=<diskname>Be sure to change the two arguments above!
if should point to the image you downloaded from step 1, and of should be the diskname.This command can take a while, and it doesn't show any status or progress updates - be patient. If it fails, try decreasing the
bs argument to 1m instead of 4m - this will slow things down but will decrease the chance of failure. If you still have issues reach out on the forum.6. When it completes, you can plug the SD card into the RPi. You will need to update the server code and potentially the
conf.yml with the latest code from GitHub.Writing an image to save your full Raspberry Pi configuration.
Useful to save time when reimaging your Raspberry Pi if you want to go back to your custom Python code and calibrations as quickly as possible.
