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...

Hi Colin,

The flag did the short term trick! The data is sent to you for your reference.

Thanks!

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I have bought 168 of these XU232 chips , I hope we can get it sorted...Is there any unpublished reference design I can lean on?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