Reviewer: ljcr84 - favorite favorite favorite favorite - May 30, Subject: Thanks Internet Archive. A wonderful journey to a not that distance past. If you want to learn the inner working of the relationship between the bare metal and the software, give this book a try.
I just glance through the code I'll give it another try went my C and PDP assembly language get improve , but I learnt a lot though. Books for People with Print Disabilities. Internet Archive Books. Scanned in China. Software in the lab automates back-end allocation, download, and console interaction, making it easy for a student to compile an operating system image, allocate an unused back-end, establish a window that connects to the back-end console port, download the compiled image into the memory of the back-end, and run the image.
The lab makes it easy for students to experiment with operating systems and protocol software. In our lab, we use two computers for Xinu: a conventional computer used to compile a Xinu image, and second,, otherwise idle, back-end computer, into which we download and run the image. Either of the platforms is relatively inexpensive and available from commercial web sites.
There are several ways to experiment. For the BeagleBone Black, the quickest was to get started involves using a serial cable. You can download a instructions that explain the above in detail for the BeagleBone Black; there are two sets: A github repository with instructions by Jamie Arrocha.
A text document with instructions from students at Purdue. For the Galileo, the quickest way to get started involves using an SD memory card and a serial cable. Connect the serial cable from the board to a PC inexpensive cables are all that one needs. Run a terminal emulator, such as minicom to display the serial output in a window on the PC.
Unplug the SD card from the PC and plug it into the experimenter board. Boot the board, and use the console serial connection to boot the image from the SD card. Output from Xinu will be displayed over the serial line. The second way to experiment takes more time to set up, but allows one to recompile and download quickly once the pieces are in place.
As described above, a serial line must be connected from the experimenter board to a PC. In addition, one must: connect a board to an Ethernet switch, connect a PC to the same switch, configure the board to boot over the network, and configure the PC to run DHCP and TFTP server processes that supply the information needed to boot. Once all the above has been set up, it is possible to compile Xinu, place the image in a file on the PC, and then power-cycle the experimenter board to boot the Xinu image automatically.
We use this approach in the lab to enable a rapid edit-compile-download-test cycle. You can download a document that explains the above in detail for the Galileo board both Generations 1 and 2. We enthusiastically endorse the two approaches above because they allow Xinu to run on real hardware and provide users with the best experience in designing systems.
For situations in which users cannot afford an experimenter board or prefer not to touch real hardware, we have a version of Xinu that runs in a Virtual Machine VM environment, which means it can run on a conventional computer with no extra hardware. The Xinu code for the VMWare version is from the first edition of the text porting the Virtual Box version from the second edition of the text to VMWare may be straightforward; so far, no one has volunteered to try.
The Virtual Box version is based on code from the second edition of the text, but has a few differences. Because the emulated Ethernet differs from the Galileo Ethernet, the Ethernet driver has been replaced. Finally, references to other memory-mapped functions have been replaced e. Note: the interrupt mechanisms in the x86 versions has been upgraded from the text to use a newer x86 interrupt controller. Tom has been working with embedded hardware, including BeagleBone and Galileo boards.
He created his own operating system, but we won't talk about that here. Tom has prepared some notes on booting Xinu on the BeagleBone Black and the use of uboot as well as notes on the Galileo and its performance.
Tom's notes may be helpful in understanding how to set up Xinu and what to expect from the hardware.

Xinu in Industry If your company has used Xinu in the past or is using Xinu at present, send a note to xinu-info cs. If your university has used Xinu in the past or is using Xinu at present, send a note to xinu-info cs.
It's not like other books I tried to read -- they gave me a headache. I have already started telling friends how great it is. Barnard Software writes that they are using Xinu as a part of a product. Dave Peterson of Woodward. See the webpage woodward. Mantissa Corporation writes to say that they have ported Xinu to an IBM z9 that's the current high-end mainframe.
Douglas Beattie Jr. They need information on how to write additional device drivers. There looks like a lot of useful information in this book.
I can't seem to put it down -- in fact, it could save my job. His task is to port Xinu to a Zilog eZ80 microprocessor platform.
