а вот за это уверенная 5 и респект!

На олимпиадное тут не тянет, даже далеко не тянет. p.s. форумчанам просто *бут мозх

это не интересно. Интерес от 100 метров до 1-5 км.

День добрый! Интересует, возможно ли передать HD, FullHD видео посредством RF? видео конечно же пожато mpeg4 Может быть есть уже готовые решения?

one-net ставится поверх cc110x

вы имеете такое же "отношение" к этой теме, как и все участники форума ТС и вы нашли друг друга, больше добавить нечего

что там осваивать то? куда вам столько? схемы достаточно как срок определили? пары часов работы на все, не более

мне страшно за военных, отдают работу каким то полуинженерам

судя по: "If "kgdb:waiting dor connection from remote gdb" isn't early enough for you, you're going to have to try something other than kgdb. Think about this: kgdb is a service provided by the kernel. You can't debug the kernel "from the beginning" because the kernel has to perform enough initialization for it to provide the kgdb service." начать отладку со start_kernel() невозможно

sasamy, Вы не подскажите, могу я прикрутить DDD для графической отладки ядра и начать отладку с start_kernel()?

Может быть проблема в том, что физически ttyO0 подключен через hub controller к хосту и поэтому не грузится kgdb? если да, то возможно ли реализовать нечто подобное, чтобы осуществлять отладку через USB? В гугле нашел нечто подобное, но очень очень обзорно.( напримерhttp://bootloader.wikidot.com/android:kgdb ) т.е. получается, что у USB драйвера должны реализованы I/O poll функции для kgdb. Подскажите с чего начать пожалуйста? Ведь с одной стороны, вывод осуществляется через tty драйвер( в моем случае через omap_serial ), где реализованы все эти три функции, с другой стороны нужно эти же функции реализовать для usb драйвера. Помогите пожалуйста разобраться

проблема в чем то другом... даже попытки инициализации kgdb нет при старте ядра, как будто ядро не реагирует на опции kgdboc и kgdbwait kgdbretry тоже не спасает

да, реализованы drivers/tty/serial/omap-serial.c #ifdef CONFIG_CONSOLE_POLL static void serial_omap_poll_put_char(struct uart_port *port, unsigned char ch) { struct uart_omap_port *up = (struct uart_omap_port *)port; wait_for_xmitr(up); serial_out(up, UART_TX, ch); } static int serial_omap_poll_get_char(struct uart_port *port) { struct uart_omap_port *up = (struct uart_omap_port *)port; unsigned int status = serial_in(up, UART_LSR); if (!(status & UART_LSR_DR)) return NO_POLL_CHAR; return serial_in(up, UART_RX); } #endif /* CONFIG_CONSOLE_POLL */ #ifdef CONFIG_SERIAL_OMAP_CONSOLE static struct uart_omap_port *serial_omap_console_ports[4]; static struct uart_driver serial_omap_reg; static void serial_omap_console_putchar(struct uart_port *port, int ch) { struct uart_omap_port *up = (struct uart_omap_port *)port; wait_for_xmitr(up); serial_out(up, UART_TX, ch); } static void serial_omap_console_write(struct console *co, const char *s, unsigned int count) { struct uart_omap_port *up = serial_omap_console_ports[co->index]; unsigned long flags; unsigned int ier; int locked = 1; local_irq_save(flags); if (up->port.sysrq) locked = 0; else if (oops_in_progress) locked = spin_trylock(&up->port.lock); else spin_lock(&up->port.lock); /* * First save the IER then disable the interrupts */ ier = serial_in(up, UART_IER); serial_out(up, UART_IER, 0); uart_console_write(&up->port, s, count, serial_omap_console_putchar); /* * Finally, wait for transmitter to become empty * and restore the IER */ wait_for_xmitr(up); serial_out(up, UART_IER, ier); /* * The receive handling will happen properly because the * receive ready bit will still be set; it is not cleared * on read.

спасибо, у меня драйвер: Serial: 8250/16550 driver там эти функции реализованы и CONFIG_CONSOLE_POLL в конфиге включено

День добрый! Столкнулся с проблемой для cortex-A8. Не загружается отладчик ядра во время стартапа ядра. Делаю вроде все правильно, по инструкции http://www.linuxforu.com/2011/09/kernel-sp...ggers-in-linux/ ядро версии 3.x.x ( 3.2.18 ). Отладчик ядра запускаю по 232 порту, т.е. over console( ввиду того, что в ядре версии > 3.x.x kgdb over ethernet исключили ). параметры, которые я дополнительно передаю ядру: kgdboc=ttyO0,115200n8 kgdbwait пробовал и так: kgdb8250=ttyO0,115200n8 kgdbwait но все равно, во время старта kgdboc не подгружается. Кто нибудь может подсказать, как запустить его и в чем может быть проблема? Есть какие нибудь идеи?
