Hey,
for a project of mine (a USB audio interface), I have adapted the xCORE 200 eXplorer schematic as included in xCORE-200-explorerKIT-Hardware-Manual%281.2%29.pdf as best as I could.
Contrary to the eXplorer kit, my design is USB bus-powered, and contains a bunch fewer components. I will be using the XEF216 variant of the chip with built-in flash, so there is no external flash in my design.
As this is my first XMOS design, I would appreciate it a lot if someone could review my attached schematic and point out any issues.
Thank you very much in advance,

Hi. See section 8 of the datasheet for the XEF216 for the following details:
Missing 1k PU on X0D01 to force the boot from the internal flash inside the XEF216 CPU.

Yes, otherwise you can't boot from internal flash.mon2 wrote:Hi. See section 8 of the datasheet for the XEF216 for the following details:

Thanks for pointing this out! This is now fixed.
The rest is okay, I assume? :)
