There seems to be some variability between Macchiatobin versions according to the schematics. The VDDO_H supply is connected to the eMMC VCCQ pins, and is also connected to the AP_VDDO_H pins. It is wired to the 1.8V regulator on rev 1.1 schematics, but hard-wired to the 3.3V regulator on rev 1.3 schematics. This needs clarification from SolidRun before the patch can be accepted - was VDDO_H ever wired to the 1.8V regulator on production hardware? -- RMK's Patch system: https://www.armlinux.org.uk/developer/patches/ FTTP is here! 40Mbps down 10Mbps up.
