topic What is QIXIS? in Layerscape https://community.nxp.com/t5/Layerscape/What-is-QIXIS/m-p/1745610#M13533 <P>Hi, I've got LS1028ardb board. As I understand there is a CPLD on this board that acts as a system controller (available through i2c) responsible for e.g. writing some configuration, performing resets, and so on, am I right?</P><P>I've checked the u-boot sources as well as the Reference Manual for this board and I've stumbled upon the terms "QIXIS"(u-boot) and "QIXIS Programming model" (manual), but I'm not sure what this exactly is. Is it a kind of standard that defines the communication with CPLD? If so, where can I find some more information about it?</P><P>If I wanted to develop a custom SBC based on LS1028ARDB design and include my custom CPLD that would have similar responsibility that the CPLD on LS1028ardb has, would I be able to reuse this "QIXIS Programming model" or perhaps is it strictly connected to the "implementation" of LS1028ardb CPLD?</P> Wed, 25 Oct 2023 05:18:00 GMT rdr3e 2023-10-25T05:18:00Z What is QIXIS? https://community.nxp.com/t5/Layerscape/What-is-QIXIS/m-p/1745610#M13533 <P>Hi, I've got LS1028ardb board.
