I’d like to understand this quote from the Hikey user hardware manual :
"[about i2s signals] the optional DI signal is not implemented on the HiKey board."
According to the HW schematics it seems this pin is wired from the hi6220 to the LS
expansion port. What’s missing ?
I should be able to test it myself in a few weeks but I’m gathering as much info as I can beforehand.
