I’m using UARTA RTS as a GPIO with a relay, which gets activated when UARTA is used (at boot for instance). I don’t want to use RTS in any case, just TX/RX. I’ve tried disabling/setting as GMI the corresponding pinmux in board-colibri_t30-pinmux.c
//DEFAULT_PINMUX(ULPI_DATA3, UARTA, NORMAL, NORMAL, INPUT), DEFAULT_PINMUX(ULPI_DATA3, GMI, NORMAL, NORMAL, INPUT),
But it doesn’t make any difference.
Also, how can I enable the Quiet option at boot in Tegra?
