uBoot и MMC0 - грузится, но раздел не видит

Recommended Posts

Доброго времени
Вот такой странный глюк. MMC0 - microSD, MMC1 - eMMC
eMMC видит (mmc info даже всё показывает: ширину шины, версию, объём и т.д.), а то, с чего загрузился (uSD на MMC0) -- нет... Это как?

первичный bootloader считал с uSD загрузчик u-boot и отдал туда управление. и считанный u-boot продетектит то железо, которое в нем прописано. это ж очевидно.

надо в исходниках убута проверять все, что касается mmc0 - разрешение тактирования, правильные контакты, их функции, наличие-отсутствие Card Detect и подобное. также проверить в исходниках, что контакты под mmc0 не заняты под какие-нить другие узлы (i2c, spi, gpio)

В данном случае конфиг стандартный am335x_evb_defconfig, у меня mmc0 на тех же пинах, впрочем, как и mmc1

А вот CD да, надо проверить, мог и перенести.

Проверил. Смещение правильное, всё как надо
 

        mmc1_pins: pinmux_mmc1_pins {
                pinctrl-single,pins = <
                        AM33XX_IOPAD(0x900, PIN_INPUT | MUX_MODE0) /* (G17) mmc0_clk.mmc0_clk */
                        AM33XX_IOPAD(0x904, PIN_INPUT | MUX_MODE0) /* (G18) mmc0_cmd.mmc0_cmd */
                        AM33XX_IOPAD(0x8fc, PIN_INPUT | MUX_MODE0) /* (G16) mmc0_dat0.mmc0_dat0 */
                        AM33XX_IOPAD(0x8f8, PIN_INPUT | MUX_MODE0) /* (G15) mmc0_dat1.mmc0_dat1 */
                        AM33XX_IOPAD(0x8f4, PIN_INPUT | MUX_MODE0) /* (F18) mmc0_dat2.mmc0_dat2 */
                        AM33XX_IOPAD(0x8f0, PIN_INPUT | MUX_MODE0) /* (F17) mmc0_dat3.mmc0_dat3 */

                        AM33XX_IOPAD(0x9a0, PIN_INPUT | MUX_MODE7) /* (B12) mcasp0_aclkr.gpio3[18] */

 

Тфу ты.. реально глаз замылился уже(( в описании-то не поправил пин, так и остался как gpio0_6
 

&mmc1 {
        status = "okay";
        bus-width = <0x4>;
        pinctrl-names = "default";
        pinctrl-0 = <&mmc1_pins>;
        cd-gpios = <&gpio0 6 GPIO_ACTIVE_LOW>;
};

изменил на gpio3_18 и заработало

Продолжу здесь уж, дабы не плодить тем...
Итак, у меня сообщение:
Starting kernel ...
и тишина... пробовал менять имя консоли (ttyS0, ttyO0...), но не помогает. Через некоторое время (секунд 20) перезагрузка и по кругу
никаких других интерфейсов, кроме uart0, пока нет
Куда посмотреть?

uEnv.txt:
 

bootpart=0:1    
devtype=mmc        
bootdir=    
bootfile=zImage    
bootpartition=mmcblk0p2    
console=ttyO0,115200n8     
loadaddr=0x82000000    
fdtaddr=0x88000000        
fdtfile=am335x-um40sv2.dtb
#set_mmc1=if test $board_name = A33515BB; then setenv bootpartition mmcblk1p2; fi
set_bootargs=setenv bootargs console=${console} root=/dev/${bootpartition} rw rootfstype=ext4 rootwait
uenvcmd=run set_bootargs;run loadimage;run loadfdt;printenv bootargs;bootz ${loadaddr} - ${fdtaddr}

zImage лежит тут же, в FAT

1 минуту назад, toweroff сказал:

прям, когда, казалось бы, висит, набрать в uart0 эту фразу?

нет, это надо добавить в строку загрузки ядра, там где console=

тогда ядро выведет расширенную отладку для понимания происходящего при загрузке

Еще проверить, что в конфиге разрешено.

у меня для am3354 прописано

console=ttyS0,115200n8

loadaddr=0x80200000 - с адресом надо быть внимательным и указать при сборке ядра

еще полезно посмотреть вывод bdinfo для проверки номера борды

U-Boot# bdinfo
arch_number = 0x0000106E
boot_params = 0x80000100
DRAM bank   = 0x00000000
-> start    = 0x80000000
-> size     = 0x10000000

 

еще надо проследить, что dtb лежит где надо и грузится, иначе картина будет подобной (для примера чуть изменил имя dtb)

U-Boot# boot
mmc0 is current device
Scanning mmc 0...
3034840 bytes read in 219 ms (13.2 MiB/s)

и все, тишина. при правильной dtb грузится без проблем

что-то не нашёл, где посмотреть в сборке ядра LOADADDR. Пробовал и 82000000, и 80200000
пока всё равно на том же месте((

LOADADDR можно задавать разными способами, например

перед запуском сборки ядра командой export LOADADDR=0x82000000

или прописать ее в .bashrc

или в команде сборки make -j8 zImage ARCH=arm LOADADDR=

ничего страшного, бывало и 3 дня ядро запускал и неделю. еще раз внимательно проверьте все структуры и параметры для вашей системы, например размер ОЗУ в dts и подобное (я бы файл eEnv.txt убрал, чтобы исключить конфликты между uEnv и dtb, ну мало ли)

лучше всего иметь комплект исходников от производителя и шпаргалку, по которой их собирать. и на их основе запускать свою кастомную систему

Продолжаем упражнения) Я собирал последнее (отсюда: https://github.com/beagleboard/linux/ ) ядро - 5.10
Откатил до 5.4, собрал. Есть движение вперёд, но стопор всё равно есть
