I’m looking through the BeagleBone System Reference Manual, and I can’t seem to find the UART3_RXD on the headers. In looking through the /sys/kernel/debug/omap_mux, It’s mux 2 on the spi0_cs1.gpio0_6, but I cant find that either.
root@beaglebone:/sys/kernel/debug/omap_mux# cat spi0_cs1
name: spi0_cs1.gpio0_6 (0x44e10960/0x960 = 0x0037), b NA, t NA
mode: OMAP_PIN_OUTPUT | OMAP_MUX_MODE7
signals: spi0_cs1 | uart3_rxd | NA | mmc0_pow | NA | mmc0_sdcd | NA | gpio0_6
Anybody know how to get to this?
