ZCU104 Linux kernel starting hangs on "Waiting for root device dev/mmcblk0p2..." #38

Closed Livius90 closed 2 years ago

Livius90 commented 2 years ago

Linux kernel starting is hanged on at "Waiting for root device dev/mmcblk0p2..." step for infinity time on ZCU104 board, in SD card booting mode.

I am using Yocto 2020.2 release for Linux building and i have no any custom modification in ZCU104 machine recipe, i am using default device-tree and xsa files from xilinx meta layers. I would like to test ZCU104 Linux build on SD card image booting (boot + rootfs partition), and i am following the "UBOOT_EXTLINUX" boot method from this "how to" page.

This is my booting log:

I tested it on Yocto 2021.1 release, also. In 2021.1, i got the same problem but i have more error printing.

I found the solution for this issue. @mhatle can review and merge my fix in device-tree-xlnx repo for it? https://github.com/Xilinx/device-tree-xlnx/pull/17

kothuriman commented 2 years ago

Please use the following bootargs command in u-boot menu

setenv bootargs 'console=ttyPS0,115200n8 root=/dev/mmcblk0p2 rw rootfstype=ext4 rootwait earlycon clk_ignore_unused uio_pdrv_genirq.of_id=generic-uio cpuidle.off=1 maxcpus=4'

It can not resolve the problem. The final solution can be found in this Xilinx forum topic: ZCU104 Linux kernel starting hangs on "Waiting for root device dev/mmcblk0p2..."

Problem is that the sdhci1 device-tree node is not configured well probably for all Xilinx Zynq board. I got this issue in my Zynq 7000 and Zynq Ultrascale+ boards, too.

Livius90 commented 2 years ago

Solution: Fix sdhci1 node in device-tree, i added my following modification in system-user.dtsi

&sdhci1 {
    no-1-8-v;
    bus-width = <4>;
    disable-wp;
    cd-gpios = <&gpio 45 1>;    // cd-gpios = <&gpio 45 GPIO_ACTIVE_LOW>;
