Pins I wanted to use are defined in the pinmuxes in am335x-bone-common-universal-pins.dtsi, but they don't seem to be actually used by any peripherals. The problem is, both the DTB and the overlay seem to be loaded correctly on boot, but the overlay changes don't seem to be applied at all. The AM335x Cortex-A8 Overview has links to TI hardware designs based on AM335x. I've set it up so it uses the am335x-boneblack.dtb and I'm trying to enable a custom overlay which claims some pins for the PRUSS. For more information, see the Emulation and Trace Headers Technical Reference Manual.

The problem is, both the DTB and the overlay seem to be loaded correctly on boot, but the overlay changes don't seem to be applied at all. SDRAM (and other) output clocks are internally looped back Do not forget to install a JTAG connection JTAG: Make sure to use the RTCK pin on the JTAG connector.
