See http://forum.xda-developers.com/showthread.php?t=1461986 You would get output on ttyFIQ0. Also to prevent it from switching to JIG mode (1) and disabled console (2) apply two hacks: 1. 429 --- a/drivers/misc/fsa9480.c 430 +++ b/drivers/misc/fsa9480.c 431 @@ -531,7 +531,8 @@ static int fsa9480_detect_callback(struct otg_id_notifier_block *nb) 432 } else if (dev_type & DEV_JIG_MASK) { 433 if (!(nb_info->detect_set->mask & FSA9480_DETECT_JIG)) 434 goto unhandled; 435 - _detected(usbsw, FSA9480_DETECT_JIG); 436 + //_detected(usbsw, FSA9480_DETECT_JIG); 437 + _detected(usbsw, FSA9480_DETECT_UART); 438 goto handled; 439 } else if (dev_type & DEV_USB_OTG) { 440 if (!(nb_info->detect_set->mask & FSA9480_DETECT_USB_HOST)) 2. 3 --- a/arch/arm/common/fiq_debugger.c 4 +++ b/arch/arm/common/fiq_debugger.c 5 @@ -768,10 +768,10 @@ static bool debug_handle_uart_interrupt(struct fiq_debugger_state *state, 6 debug_prompt(state); 7 } 8 } else if (c == FIQ_DEBUGGER_BREAK) { 9 - state->console_enable = false; 10 - debug_puts(state, "fiq debugger mode\n"); 11 - state->debug_count = 0; 12 - debug_prompt(state); 13 + //state->console_enable = false; 14 + //debug_puts(state, "fiq debugger mode\n"); 15 + //state->debug_count = 0; 16 + //debug_prompt(state); 17 #ifdef CONFIG_FIQ_DEBUGGER_CONSOLE 18 } else if (state->console_enable && state->tty_rbuf) { 19 fiq_debugger_ringbuf_push(state->tty_rbuf, c); Of course, you could get it working without these hacks. -- -- unsubscribe: android-kernel+unsubscr...@googlegroups.com website: http://groups.google.com/group/android-kernel --- You received this message because you are subscribed to the Google Groups "Android Linux Kernel Development" group.
