Introduction to Microcontrollers Mike Silva. Arduino Robotics Lonnie Honeycutt. We modified the delivered BSP to allow us to have shared memory windows across all processor cards. Now, our problem appears to be that the auto syscon feature of the board is not working properly. That is to say, if any controller, not in slot 0, is present and has auto-config jumper set to AUTO.
So far so good. Now, after a slave access of syscon slot 0 shared memory, any accesses across the VME bus, result in a hang. We verified the same behavior across multiple cards with various RAM amounts --get the same result.
On Mon, 08 Jan I rather much wonder if this isn't some issue with the RMW mechanism being used within VxWorks resulting in a lock on the local bus. Such nasty behavior isn't seen if the transfers are not into shared memory spaces. My recollection on the auto-config jumper is that it's sensed by the Universe at initialization to determine if it needs to provide bus arbitration and isn't used afterwards. That this problem comes and goes depending whether auto-configuration or not is selected does suggest otherwise; but I doubt the root cause is the jumper setting.
There are no stupid questions, but there are a LOT of inquisitive idiots. This is what I thought as well. I do recall at a previous employer we had similar issues with the same Tundra chipand the workaround was extra crap that the BSP had to perform during initialization On Mon, 15 Jan The point is that if the memory spaces weren't shared the transactions would succeed, otherwise Tundra wouldn't be able to sell chip one. I suspect your implementation is drawing out a latent defect in the implementation of shared memory; I'm aware of another who encountered a similar hang using a more standard configuration but totally weird in other ways.

It is physically based on Eurocard sizes, mechanicals and connectors DIN , but uses its own signalling system, which Eurocard does not define. It was first developed in and continues to see widespread use today. In , during development of the Motorola CPU, one of their engineers, Jack Kister , decided to set about creating a standardized bus system for based systems.
Sven Rau and Max Loesel of Motorola-Europe added a mechanical specification to the system, basing it on the Eurocard standard that was then late in the standardization process. At this point, a number of other companies involved in the 's ecosystem agreed to use the standard, including Signetics, Philips, Thomson, and Mostek.
The original standard was a bit bus, designed to fit within the existing Eurocard DIN connectors. However, there have been several updates to the system to allow wider bus widths. In the late s, synchronous protocols proved to be favourable. The research project was called VME Over the years, many extensions have been added to the VME interface, providing 'sideband' channels of communication in parallel to VME itself.
To demonstrate the concept, Max Loesel and Sven Rau developed three prototype boards: In early , Motorola, Mostek and Signetics agreed to jointly develop and support the new bus architecture. These companies were all early supporters of the microprocessor family. They also placed Revision A of the specification in the public domain. This new revision refined the electrical specifications for the signal line drivers and receivers and brought the mechanical specification further in line with the developing IEC standard the formal specification for Eurocard mechanical formats.
Wayne Fischer was appointed first chairman of the working group. John Black served as chairman of the P Technical Subcommittee. These comments made it clear that it was time to go past Revision B. It was agreed that a Revision C should be created and that it should take into consideration all the comments received by the three organizations. John Black and Shlomo Pri-Tal of Motorola incorporated the changes from all sources into a common document.
Read on to find the best NAS devices for both the home and office. Plus, if you want to boost the storage of your existing NAS, you can head over to our list of the best hard drives — we got you covered there, as well. Choosing the best NAS device for your needs doesn't have to be complicated and confusing.
In this guide, we'll show you the very best network attached storage devices that money can buy in , as well as detail everything you need to consider when looking into buying a new NAS device. Before we get into any of that, however, we should probably explain what a NAS is. The best NAS devices are essentially external hard drives that connect to your network, rather than your PC. The best NAS setups also allow for remote access, so you can use your files from the other side of the world, if the need arises.
In addition, the best NAS devices are platform-agnostic, which means you can access them from whichever device is handy no matter the software it runs on.
When buying the best NAS device for your needs, there are a few things you must consider. First of all is storage space. Many of the best NAS devices on this page come with hard drives already installed. Remember you'll want enough space to hold all of your important files, and sometimes even your backups. Some of the best NAS devices that come without hard drives, so you'll need to buy one separately. This gives you a bit more flexibility when it comes to the size — and speed — of the NAS device, and if you shop around you could save yourself some money.
You should also consider backup and data redundancy measures for the NAS drive. Some of the best NAS drives can hold multiple hard drives. The best NAS drives will also allow you to easily backup the data onto an external hard drive for additional protection and in case you need that data to be more portable.
