Re: Connect bits streams at 13Mhz to XCORE

Michel,

Have a look at these two pages, they should cover what you need:

Re: xCORE-AUDIO Hi-Res DAC/HPA Platform Hardware(DAC) volume

Hi Russ, Have you looked at the using xCORE-200 and the USB device reference design? The USB design guide describes the features (https://www.xmos.com/download/private/sw_usb_audio%3A-sw_usb_audio-%5Bdesign-guide%5D%286.16.1alpha1%29.pdf). You may be able to adapt the design to suit your needs. Rob

Re: Warning: port "XS1_PORT_1B" on tile[1] is not connected.

Hello,

These pins are not bonded out the external package pins, but are used internally to connect to the RGMII block.

Re: SRAM interfacing to XMOS XS1 devices

Good morning, Please consult lib_sdram for details on the SDRAM support. XMOS SDRAM library There is also a slice board which implements a SDRAM device. The details are found here : SDRAM Slice Note, that due to an error in routing the xCORE200- SliceKits are not suitable for SDRAM evaluation. DDR i...

Re: Performing I/O on Specific Clock Edges on high speed adc

Hello, I think you've spotted a bug in the code for this application note - I'll submit a bug report. You are right, ts is not initialised before it's used for the first time in : p_rd @ (ts+5)<:0x00010001 ; However, when the code reaches this line : p_sdob:> data_2 @ ts; ts will be initialised to t...

Re: xflash erases data partition?

Hello,

This is the expected behaviour of the command.

Can you specify the contents of the data partition when you re-flash the firmware using --data option?

Re: To XMOS staff: buy one component in a kit (XA-SK-AUDIO-P

Hi,

The PLL used on this board was specifically added for the AVB application and as such has only been used with the daisy chain kit.

thanks,

Re: To XMOS staff: buy one component in a kit (XA-SK-AUDIO-P

Hi jerryXCORE,

These two slices (XA-SK-AUDIO and XA-SK-AUDIO-PLL) are different and you need the XA-SK-AUDIO-PLL one to work with AVB due to the adjustable PLL.

Unfortunately this is only available in the Dasiy-chain kit, and not supplied separately.

Sorry,

Rob

Re: Processor Recommendation

The xCORE-200 Multichannel Board uses an XE216-512 device. For a USB only application the XU216-512 would be more appropriate. I'd start with this and then look at the resources required once you've configured and compiled the reference design code (which basically does exactly what you need). I sus...
