SUBARCTIC Windows drivers missing and FTDI ok

Stefano Rossi

Hi everybody, I installed FTDI drivers for AM335x starter kit and I'm able to debug my device with CCSv5 on Windows Vista; the only issue I still have is about Windows trying to install the driver for the SUBARCTIC device .   Windows continues trying to recognize the SUBARCTIC device and sometimes this causes connection troubles with the AM335x kit.  It doesn't seem clear where to find the drivers for SUBARCTICT (Windows).

Any suggests? 

Thanks in advance

Stefano

    Hi Rafael, I already quickly visited the link before, but I'm not working with Linux and I need Windows drivers for SUBARCTICT.

    Stefano,

    I see that it seems the issue was solved per your other thread.

    Sorry, I thought there was a specific device driver for this, but I checked internally with some people and they mentioned this is an expected behaviour caused by the AM335x attempting to boot load from USB. By booting the board via the SD card or Ethernet, the bootloader does not attempt to boot from USB anymore and the "device" SUBARCTIC goes away.

    BTW, on newer silicon revisions this was changed to something more meaningful such as AM335x or similar (I don't have such newer board to see it myself).

    Cheers,

    Rafael

    Hi Rafael, in fact I fixed the issue. Thank you, anyway.   Now I got troubles with linking options and memory mapping:  i'm a NI labview and hardware designer  but I'm just new to the CCS - ARM world, so I waste large amounts of time collecting every detail to make the entire stuff working.  In my opinion,  there is the need for a complete step-by-step starter guide to the starter kit (  :)  ); a well organized book, I mean, where the first obvious things as well as tips and tricks for complex projects can be found quickly. I'd gladly spend money for such a book!  I also think this could be a good way to promote the purchasing of other, more specialized, TI embedded developing systems.

    Hope to see this soon on Amazon or else!

    Thank you for your time!

    Ste,

    That is a good idea. We started developing the concept of handbooks that cover the TI software development in a more "textbook" form. You can check the first one that talks about the project and code development process (developed by AartiG):

    http://processors.wiki.ti.com/index.php/Projects_and_Build_Handbook_for_CCS

    Regards,

    Rafael

    Edit: we will eventually come up with one for that covers the debug aspects of CCS, so the entire picture becomes more complete.

    Thank you Rafael, I think it might be useful (of course) to read in such a book also some very detailed CCS project examples with all the steps and choices made by the designer related to code optimization, linking and compiling options, memory issues and a very accurate focus about the AM335x starter kit hardware usage (PRU, ARM, etc.).

    I'm aware this would be a big writing work ( and this is just one kit of yours), I think we should pay for it,  and I also believe it would give a great payback by your customers.

    Regards

    Hi Stefano,

    I suffered the same question with you but still seeking the solution. Could you kindly provided your solution for me.

    Thanks for your help.

    Hi Kevin, if you put a bootable SD card in the SD reader, the issue is solved. There's no need for a driver. Alternatively, I think it may be possible to change the booting settings for the Starter kit.

    More, you can also simply ignore the issue, launching CCS debug mode before Windows disconnects the starter kit; after the first successful launch, booting from SD reader is stopped until power supply is disconnected from the kit.

    regards!
