Re: Reboot/Soft Reset possible?
Sorry for opening such an old thread but I wanted to share this with you and see if I am not missing anything here. I have tried endlessly to soft reset an XU232, one tile after the other like the application notes and some suggestions on the forum here (for example https://www.xcore.com/viewtopic.p...

Linux bit depth crash - fixed
Hi All, This is for anyone who experienced USB audio dropouts on Linux based hosts. I could not find any references to this issue online, forgive me if I post something here that is old news. Our design is based on the sw_usb_audio-[sw]_6.15.2rc1 release. The issue we encountered is that if you play...

Re: XU232 QSPI & Xlink boot
Hi Colin, I found the issue - my bad, should have spotted it. I checked the VDD core voltage against the design checklist in the beginning of the debug process, obviously with an off-spec multimeter. Turns out VDD core was running at 1.07V. This will let the device boot normally from XTAG, but not f...

XFlash libcompressor time - large data array in program
Hi, We have a large data array included in our source code in a header file. It is declared as: uint name[]= { 0x..., 0x..., etc }; The size is >100kByte. This works and runs fast (<1minute) when building and running/debugging with the XTAG. Now we want to flash this image onto the board with xflash...

I have bought 168 of these XU232 chips , I hope we can get it sorted...Is there any unpublished reference design I can lean on?

Re: AN00170 "Using the SDRAM library"
Hi infiniteimprobability, Not sure if this is the right place to ask this; Could the lower 16 of PORT32a (32A0-32A15) of an XU232 on X1 also function as the dq_ah port? I assumed it could earlier on without digging to deep so I went ahead and made custom hardware for it with an IS42S16400J-7BL. Now ...

Re: XU232 QSPI & Xlink boot
Hi Guys,
I was wondering if anyone would have another suggestion for me or review the provided results to try and find the root cause of this issue.
I'm building a second board now to make sure it is not hardware related.
Thanks in advance!

Re: XU232 QSPI & Xlink boot
Hi Henk, After finally finding by trial on error what the correct syntax is to get xflash to accept the --erase-all command, I'm posting it here for future reference: xflash --erase-all --target-file xnfile.xn Maybe it is described somewhere in a manual but I couldn't find it, nor conclude it from t...
