Re: XMOS audio channel limit 48 channels at 176.4 kHz

I've been planning to do some experiments with the more recent extension to UAC2 that allows larger maximum data packet. I was only aware of it because our friend at Apple told us about OSX support for it. But I don't have the spec. I think he said that this is a feature that is associated with USB ...

Re: XU208 BCLK jitter ES9038PRO

I have no experience with native DSD. We never did implement it in our products. When we considered it a few years ago, it wasn't clear if it was possible with OSX. We've had almost 0 requests for implementing it. I'm not clear how DoP would work at DSD512 data rates. At a maximum data rate of 8.192...

Re: XU208 BCLK jitter ES9038PRO

If you are using a X200 device, your BCLK should be configured as clock output that is divided from mclk. See in audio.xc: #ifndef CODEC_MASTER static inline void doI2SClocks(unsigned divide) { #ifndef __XS2A__ switch (divide) { #if (MAX_DIVIDE > 16) #error MCLK/BCLK Ratio not supported!! #endif #if...

Re: ‎XUF208 boot glitch

For this sort of problem, I first look at power supply sequencing. Board integration section of datasheet:

Re: Error making upgrade image for --factory-version 11

Hi, Again thank you very much for you assistance. This gives the same failure. Substituting 12 for the actual version 11 produces exactly the same binary file. And xntools --add-routing-12 makes the same changes to the .xn file as xntools --add-routing-11 All permutations I've tried either result in...

Re: Error making upgrade image for --factory-version 11

Hi Mon2, I'm grateful for you reply and effort on this. The instructions that you got from XMOS (UK) are exactly what is found in the document that I posted in my previous message. I could have detailed the steps. Unfortunately, this generates an upgrade image does not load correctly and also causes...

Re: Error making upgrade image for --factory-version 11

I found this document: https://www.xmos.com/download/XFLASH-version-13-migration-manual(1.0).pdf/ This provides instructions for running xntools.exe to modify your .xn file (that is composed for tools 13.2 and higher) to use pre 13.2 rounting info so that it is possible to build an upgrade image tha...

Re: Error making upgrade image for --factory-version 11

Are you talking about the file xk-audio-216-mc.xn? If not, please upload it. I can't see how the error you've described could appear with that file, since it doesn't mention link 4 of node 0. No, this is for a 2-tile L1 device: XS1-L2A-QF124 The .xn file for the old MC eval kit is xr-usb-audio-2.0-...

Re: Error making upgrade image for --factory-version 11

You may have some knowledge that can help. In the original project that was built with v11 tools and the latest MC audio reference code base at that time, I used that default .xn file that was used to target the same XS2-L2A device that is on the original MC audio development board from XMOS. When I...

Error making upgrade image for --factory-version 11

We have a product that was designed using XDE Version 11.11.1 and we have distributed numerous field upgrade images that were built with the same tools over the last 8 years. In order to solve a long outstanding issue with the old codebase, I re-designed the software using current tools (XTC 14.3.3)...
