Hi I am trying to use the second UART on the J960 connectors, but the manual only provides these informations: 1. Modify your kernel: a. On file board-igep0020.c b. On function static void __init igep2_init(void) c. Afterlineomap3_mux_init(board_mux,OMAP_PACKAGE_CBB) d. Place this two lines: i. omap_mux_init_signal(\\\"uart1_rts.safe_mode\\\", 0); ii. omap_mux_init_signal(\\\"uart1_cts.safe_mode\\\", 0); 2. From kernel space: a. $ mount -t debugfs none /sys/kernel/debug b. $ echo 0x007 > /sys/kernel/debug/omap_mux/uart1_rts c. $ echo 0x007 > /sys/kernel/debug/omap_mux/uart1_cts The first option: I can\\\'t find the c file when I checkout the working tree (I want to boot android 2.2 on the board). The second option: I can find the directory /sys/kernel/debug but when I type the command it doesn\\\'t work.

    For the first option, the file is in /bin/froyo/kernel/arch/arm/ after you have downloaded the IGEPV2 kernel.
