Tool/software: Linux
Hi!
I have some trouble in our custom board based on AM335x-EVMSK.
We use SD card for booting (without wp, cd pins).
U-Boot works fine, but Kernel is hanging on these line: "Waiting for root device PARTUUID=partuuid-02..."
I was trying more variants of device tree files and mux.c in many combinations, but no one worked. Also i was trying use "stub" pin for CD pin (connected to Ground).
I read other topics about this issue, but Im still cant fix it.
MMC node:
&mmc1 { // SD Card
vmmc-supply = <&vmmc_reg>;
bus-width = <4>;
pinctrl-names = "default";
pinctrl-0 = <&mmc1_pins>;
broken-cd;
status = "okay";
};
mmc1_pins node:
mmc1_pins: pinmux_mmc1_pins {
pinctrl-single,pins = <
AM33XX_IOPAD(PIN_MMC0_DAT3, (PIN_INPUT_PULLUP | MUX_MODE0))
AM33XX_IOPAD(PIN_MMC0_DAT2, (PIN_INPUT_PULLUP | MUX_MODE0))
AM33XX_IOPAD(PIN_MMC0_DAT1, (PIN_INPUT_PULLUP | MUX_MODE0))
AM33XX_IOPAD(PIN_MMC0_DAT0, (PIN_INPUT_PULLUP | MUX_MODE0))
AM33XX_IOPAD(PIN_MMC0_CMD, (PIN_INPUT_PULLUP | MUX_MODE0))
AM33XX_IOPAD(PIN_MMC0_CLK, (PIN_INPUT_PULLUP | MUX_MODE0))

I will be appreciate with any help!
Thank you!
UPD:
Also attach kernel config file:myboard-kernel-configs-fragments.cfg
And my pinmux file (in it I put only defines): myboard_am335x_pinmux.h
