RM48 USB STACK with IAR

Other Parts Discussed in Thread: HALCOGEN

Hi everyone,

I saw in the wiki that the USB Stack for the RM48 requires the CCS, however, would work with IAR or there is some assembly code that won't make it work?

Thanks,

    Victor,

    Hi did you mean the USB stick or USB stack?

    If the USB stack - then which vendor?

    Hello Anthony,

    Fist of all, thank you for your reply,

    I have a RM48 HDK and I'm trying to make it run with IAR + FREERTOS.

    I wish to be able to use TCP/IP, USB and FileSystem Stacks.

    So as far as I know, the board includes a port from lwIP, that should solve the TCP/IP side, so I'm trying to focus on the USB.

    Looking in the Texas Instrument website I can notice about this:

    http://processors.wiki.ti.com/index.php/HALCoGen_USB_Device_-_driver_&_CDC_Class

    "The Hercules USB stack is an OS-independent USB solution..."

    So this means that Hercules provides some short of USB Stack, is that correct?

    Continuing reading the wiki page, TI specifies the CCS as a requirement. Does this means that I can't make it run with IAR?

    Thank you for your reply.

    I think it means nobody's checked it out with IAR yet. 

    So it may not work, but more likely it will and you might just need to fix an issue or two.

    HalCoGen does seem to have the USB device tab available even when you select IAR tools,  and I don't think there are any USB 'assembly language' files.   Assembly files and special #pragma in C are the main problems you run into when changing between CCS and IAR...

    So why not give it a try and let us know if it works for you - I suspect you'll be successful. If you run into a snag you can post here and we'll see if we can't get you past it.

    Hi Anthony,

    Thank you for your reply, I will give him a try as soon as I can, this might take time due my scheduled work, so I will let you know in the future.

    Thanks,
