Hi sci_spot
I am afraid, there is no sample of SGPIO with AXI.
However we have several other solutions using SGPIO:
- AN11196 LPC4300 camera interface design using SGPIO
- AN11275 SGPIO on the LPC4300
- AN11343 SGPIO camera module design using LPC4300
- AN11351 Implementing a UART using SGPIO on LPC4300
Search the AN number which you are interested on https://www.nxp.com/ you will find it.
Thanks,
Jun Zhang
