TSW14J56EVM: Custom firmware for Arria V to allow storing multiple triggered samples in RAM

Part Number: TSW14J56EVM

I am working on a synthetic aperture radar backend that utilizes the TSW14J56EVM and the ADC12J4000. The radar needs to run for at least 5 seconds with the ADC at 1.6G, but it only needs to capture about for 5us out of every 333us (this is the time that we expect to receive our chirp back). The 4GB of RAM on the capture board is not sufficient to run for 5 seconds continuously, but it is more than sufficient if we only capture during the periods that we need to.

For this reason, I want to develop firmware that will store multiple triggered captures in RAM before offloading them via USB. I read in the thread linked below that TI could provide firmware to work from and possible support. Is this still the case?

    Darren,

    If you are looking for the source code used by the Arria V device on the TSW14J56EVM, this can be downloaded for the TSW14J56EVM product folder on the TI website.

    Regards,

    Jim

    Jim,

    Thanks! I found the firmware and downloaded it. Unfortunately, when attempting to open it in Quartus Prime, the operation fails because the path exceeds 260 characters. I have long paths enabled in Windows, but the limit must be internal to Quartus because it persists. Any idea for a workaround? I'm guessing that the firmware was developed on a different version of Quartus, because the large path names are internal to the project (otherwise I would just choose a shorter path). Maybe linux... though Altera documentation indicates that the character limit applies to the software on linux and mac as well.

    Darren,

    Give this a try from our software development team.

    "Please install the firmware source codes in a folder with short path name like, "C:\TI"

    Rename the source .qar file from "TSW14J56RevD Respin Fw" to a smaller name "J56D"

     

    We did the same process and was able to restore .qar file successfully in Q14.0.

    You can keep the restored project name shorter as well, like "J56D_R"

     

    We can restore the project in other Quartus versions as well with ArriaV GZ device support installed but it is better to use Q14.0".
