Re: XHRA-2HPA-TQ64 doesn't load unique configuration data at 0x80000 addr

Hi, so I had this problem. The thread here https://www.xcore.com/viewtopic.php?t=4803 along with this one helped me solve it. The issue I had was the IS25LQ080B is EOL and was subbed with IS25LP080D. TL;DR the xflash checks the chip ID and if it doesn't match you can't flash. The app note 'custom fl...

Re: USB Audio device disappears running debugger, runs fine when flashed

-O3. I ran the stock USB audio project, and modified version to move USB core to tile 0, both run with the debugger. (audio clocks wouldn't be working though, those are assigned to different pins). Also the MQX dev kit firmware unmodified has the same characteristic (disappears while in the debugger...

USB Audio device disappears running debugger, runs fine when flashed

Here's something really odd. Code based on the USB Audio kit (the MQA dev kit).... ported to custom hardware. When flashed, code runs great. In the debugger, if I set it to break at main, it shows up (USB Prober, Mac OS X) until you hit run, then the USB device disappears. The USB Phy is connected t...

Re: XTAG-3 compatible with XS1? mine just burned out

Just powering up with our Raspberry PI 3 power supply (5V @ 3A), do see a few lights on for this XTAG-3 board (not connected to anything downstream). Some of the onboard LEDs are dim. Thanks for checking that and the picture. Yeah, on mine all those LEDs are completely off save the 3V3 green LED. I...

Re: XTAG-3 compatible with XS1? mine just burned out

yeah, i'm going to let it sit for a few days and see if it comes back to life. But if I remember right, this thing will light up more than just the 3V3 LED when it powers up (though, I haven't tried powering up from e.g. a USB power adaptor with no bus functionality to see if that's still true... if...

Is the fuse blown or in tact with your 500 ma load?
Yes, according to the schematic it's 350mA. But nope, fuse is still fine, still 5V power.

Nope, nada.

XTAG-3 compatible with XS1? mine just burned out

I have a custom design based on XS1-U6A-64-FB96 (the MIYO), it can draw up to 500mA from the 5V pin on the JTAG header interface to XTAG. I've been using an XTAG-2 for years during development of this and others, never had a problem. Recently got an XTAG-3 as part of a XC200 kit, and I was doing som...

Re: MFA Kit and AN00124 under Win7

BUMP... I'm hoping xmos can re-post AN00124 version 2.0.0 as I'm not able to get v2.0.2 to run on the XK-AUDIO-216-MC board. File not found...

Re: USB Audio self-powered not detecting cable removal/insert

old thread but just to close it out. Turns out some kind of latch-up. once the unit was powered off for like a week or 2, it came back to life and worked fine! For my prototypes, I just put a 5.1V zener on that line to keep it from going over and it's been fine ever since. Things that make you go hm...

did you ever solve this?
