sof2flash

Hi All,

I am using Ubuntu 11.1 to use Quartus, the web version, and I have been putting stuff together for a while.

However now it's time to put a design onto my dev board (the Embedded Dev board).

As with all things I need to pipeclean the flow so I have decided to use the my first fpga as a good and known design to start with.

I've successfully generated the SOF and now attempting to generate the flash file as per the instructions provided by the web server on the dev board (which I think is superb).

When command sof2flash is entered with the appropriate settings I get a response being (from memory)

Line 2 Bad Substitution.

This is from one of the sh scripts that gets called up, think sj_jar ???

One of the first few anyway.

So it's probably a short somewhere between the ears but does anyone know of any classic pipe cleaning flow issues that it would be good to know about and thus avoid ?

Thank you for any help :)

Best Regards

Andre'

    that's a rather odd message, I don't remember seeing anything like that... Do you have any spaces if your file paths/names, or any special characters?

    seems like an Ubuntu issue

    Ubuntu 11.1 Quartus II 11.0sp1 - sof2flash failed

    CentOS 5.0 Quartus II 11.0sp1 - sof2flash passes

    it would be worth reporting this to Altera since the next release will support Ubuntu, but you may be out of luck getting official support in 11.1. you might run CentOS 4/5 in a VM if you don't feel like debugging the issue

    Hi,

    here is the message

    /home/andre/altera/11.0sp1/nios2eds/bin/sh_jar.sh: 2: Bad substitution

    the line that appears to cause the problem is

    FILEPATH=${0//\\/\/}

    I am running this from a Bash shell, I've also tried it from the nios command line available from the Qsys (sp).

    for reference here's the output of sof2flash with no arguments: 

    $ sof2flash 
/home/tools/altera/11.0sp1/nios2eds/bin/sh_jar.sh: 2: Bad substitution

    Hi Pancake,

    Thanks for that, I'll pass the information on. I'll see if I can install centos in a VM, but this is a pain. The dev board is very expensive and it means that I can't actually use it :(.

    best regards

    sh_jar.sh uses /bin/sh which is actually dash. changing it to /bin/bash doesn't fix it

    here's the line in question: 

    FILEPATH=${0//\\/\/}

    did you fix it?

    the FILEPATH is trying to get the path to the script - i'd like to try and debug the line when i've got time

    Hi All,

    I've contacted Altera and although Ubuntu isn't on the supported list they have come back with an answer, I've copied below.

    One point that we have found with Ubuntu. Most things do work well, however the issue that you mention in your note is very similar to some other .sh issues that we have seen. On Ubuntu, this is commonly resolved by changing the symbolic link for /bin/sh from /bin/dash to /bin/bash:

    sudo rm /bin/sh

    sudo ln -s /bin/bash /bin/sh

    Dash and Bash have a slightly different syntax, and that gets us around most issues.

    I've given it a shot within the nios2 command shell in Qsys and it does indeed generate a flash file. I've not tried it on the board yet but this is significantly better than before.

    Thanks to Stef and Kris over at Altera.
