#Hyperterm cygwin how to#
There’s two things that usually cause confusion in loading sd cards – how to do this on Windows, and how to make sure that your image is in the right place. But the card needs to have a valid disk image on it for the system to boot from it. If you get this far, you’ve established that communication to the sd card works. If you don’t see any change, try another card. 2) Now insert a card the first led should go off immediately, and the second one too if the card is SDHC capable. You will see the first two leds light up. To check SD card connectivity, follow these simple steps: 1) power up and load, or reset the board *without* an sd card. The third is on while the card is being read, and the fourth is on while the card is written onto.
The second is on if the card is SD but not SDHC. With the new SDHC capable version, the first led is on if the controller can not communicate with the card.

All bitstreams I distribute have a group of 4 leds somewhere on the board that show the status of the controller and sd card – the rX_sdcard_debug signal, to be precise – and note that this has changed since the mid-2020 update to SDHC capable controllers the way the leds light up is now different. Next step is to establish communication with an sd card to boot from.

The original M9312 boot code in m9312x46 however will only output a single you get this far, you’ve established that a) the bitstream was loaded correctly, b) that you’re in communication with the board, and c) the boot code is running. The latter will also say ‘Hello world’, and then list the device space of the CPU – several lines of output.

After that, or as the first output for the serial consoles, you should see text that is written by the boot roms of the main CPU what you will see is dependent on the bootrom that is included – either m9312X46 or m9312X47. On the embedded terminal, you will see ‘Hello world ’ as the first message after power-up this is the boot message of the terminal CPU – if you see this, it means that the terminal code is running. Also connect a PS2 keyboard.įor either the embedded terminal or the serial console, you should see text appearing if you load the FPGA, or if you hit the button mapped to the reset input – usually that is the easiest pushbutton to reach. About any VGA capable screen will work – it is driven at 640×480, 60Hz. If you chose one of the embedded terminal bitstreams, you’d need to connect a VGA screen at this point. Some USB-to-serial converters don’t like to be configured and insist on their own idea of the right parameters sending a few return characters usually does the trick.
Not sure what the current thing on the latest versions of Windows is (mentioning hyperterm probably shows my age…).
#Hyperterm cygwin software#
On Linux, minicom is the terminal software of choice for Windows, hyperterm is the easiest to find (most people like Putty better though).
Connect a serial port, and set it to 9600, 8 data bits, 1 stop bit, no parity. The first thing to check after you’ve managed to load one of the bitstreams into a board is whether or not it is communicating on the serial port – or if the embedded terminal is.
The toolchains will probably work mostly the same on Windows, but I don’t have access to a Windows machine, so I can’t help you with it if you run into trouble. The toolchains are complex bits of software that have a steep learning curve – I suggest you try some of the tutorials and sample projects that the vendors provide.Ĭurrently, I’m using ISE 14.5 for the Digilent boards, Quartus 13.0SP1 for the pre-Cyclone IV boards, and Quartus 20.1 for the newer boards – all on Linux. You will need the vendor’s toolchain to download bitstreams onto the board, and to recompile the VHDL if you decide later that you want to create your own configuration. I strongly suggest that you start trying out one of the bitstreams I publish on the download page first, even if you’re going to build your own configuration or want to use a board that I don’t support – it will show what to watch out for but even if you don’t, what’s on this page may help you. On this page, I’ve tried to list some steps in ascending order of complexity, to make it easier to avoid pitfalls and help finding out what causes things not to work if it doesn’t go smoothly. Getting a PDP2011 system to run is a bit of work, certainly if you are not familiar with FPGA’s and the vendor toolchains required to program them.
