5370_proc | hp5370 processor board replacement project

The file READ_MORE.md elaborates on the information given here.
If your new board was purchased with the BBB already attached then the 5370 software is pre-installed and the board is ready to be plugged in. Otherwise see the section below "Installing your own BBB and software" before proceeding. Note: we no longer sell the Beagle / 5370 board combo. You must supply your own BeagleBone Black.
Install the board in your 5370. Remove the old processor board from the far left A9 slot. The boards can be difficult to remove and install. Original boards from the instrument have ejector levers to assist with this task. Grasp the board outer top edges, or use the ejector levers, and try to rock the ends up and down slightly, one at a time, to get the springs fingers of the connectors to loosen up rather than pulling the board straight out with a lot of force. Like the old processor the new one faces component-side towards the inside of the instrument. The new board is not full height (cost savings) which means the card guides on the edges don't fully engage. Be sure the board is aligned before pushing it into the connector.
The HPIB board in slot A15 can be left installed even if the app option to divert HPIB transfers to the network is used. If you have an older instrument you can remove the ROM board from slot A12. You can also leave these boards installed in case you want to revert to using the original processor board.
Although the new board will run the instrument fine without a network connection you'll probably want one to do any development. There are several ways to connect the BBB to a network and the easiest is probably by using an Ethernet cable (not included) from the RJ45 jack on the BBB to a network hub or router port. It is also easiest if your network is running a DHCP server (usually in the network router) that assigns IP addresses.
Be prepared to note the assigned IP address that will be shown on the 5370 front panel display after instrument power on. You'll need this address for a subsequent command to login to Linux running on the BBB (see below). After turning on the instrument it will take less than 30 seconds for the BBB to boot and begin running the 5370 app. The version number of the app will appear on the display, e.g. "v3.2". If you're running a DHCP server on your network the assigned IP address will then be shown on the display (e.g. 192.168.1.2). If not, a default IP address will be shown that can be changed via the front panel as described in the READ_MORE.md file. There are four blue LEDs on the BBB that should blink as booting progresses (fron the "top" edge of the board down: heartbeat, SD card access, process running, eMMC/filesystem access). If you're having trouble determining the IP address see the software installation section below for some suggestions.
Your instrument should now respond as usual although you will notice it is somewhat faster. Before powering off the instrument it is strongly recommended you first halt Linux to avoid possible unrecoverable filesystem corruption (although this is unlikely). Definitely do not power off during the booting process when lots of filesystem writes are occurring. You can halt by using the front panel menu interface or by logging into the BBB via ssh and typing 'halt'. When halting from the front-panel menu the message 'halting...' will appear and it will be safe to power-off the instrument after the display goes blank. It is also possible to keep the BBB running by using a USB-mini cable from an external hub or USB charger to keep it powered up, even with the instrument powered down. This has the advantage of providing 'instant on' when the instrument is next powered on (i.e. no Linux booting required). See the READ_MORE.md file for details.
Look at the file READ_MORE.md to learn about how to use, modify and re-compile the app. This file also discusses using "git" to track changes to the released software.
