VFS: Cannot open root device "mmcblk1p2" or unknown-block(179,26)

  • wrong fs type

    selected INITRAMFS but have no rootfs file found. use another type, e.g. INITRD, or copy the rootfs file to SD. Or device tree set wrong bootargs, check it at components/plnx_workspace/device-tree/device-tree/system-conf.dtsi

  • sdcard level-shifter/write protect issue (fixed by dt)
  • sd1-sd-20-partition-table-detected-by-uboot-but-not-by-linux-kernel 
    &sdhci1 {
    no-1-8-v; // 1.8V to 3.3V level shifter (i.e. using LVCMOS18, but sd connector is driven by 3.3V)
    disable-wp;
    disable-cd;
};

Delete the device-tree at components/plnx_workspace/device-tree/device-tree, then petalinux-build

  • you may have a broken .bin file, check if you use the following command to generate bin files. 
    bootgen -image $(BIF_FILE_PATH) -arch zynq -process_bitstream bin -w -o $(BIT2BIN_FILE)

petalinux can bootup but no uart output

  • check pin assignment on zynq block design, it's easy to mis-click to another assignment.
  • mio configurations here: project-spec/hw-description/ps7_init.html

petalinux-create can't find librdi_commonxillic.so

try (I'm not sure, this error has no bad effect for me): 

sudo echo "/opt/Xilinx/petalinux/tools/lib" > /etc/ld.so.conf.d/petalinux.so.conf
sudo ldconfig

petalinux increase CMA size (default 16)

konosubakonoakua · 2025-04-14T01:12:14Z

build/misc/config/Kconfig:223: can't open file "build/misc/config/Kconfig.syshw"

  • It's because you moved or renamed project, causing path inconsistency
  • fixed by modifying <your-project-path>build/misc/config/Kconfig.syshw in build/misc/config/Kconfig.part.

petalinux 2021 sstate cache issues

2021.1 PetaLinux: Package do_fetch task executes even though PREMIRRORS set to downloads path for offline builds

https://adaptivesupport.amd.com/s/article/2021-1-PetaLinux?language=en_US - Unset `CONFIG_PRE_MIRROR_URL` in `/project-spec/configs/config` - $ `cat project-spec/meta-user/conf/petalinuxbsp.conf` 
#User Configuration

#OE_TERMINAL = "tmux"

- delete `build/conf/site.conf` 
$ petalinux-build -x mrproper
$ petalinux-config --silentconfig
$ rm -rf build/conf/site.conf
$ petalinux-build

2021.2 and 2022.x Yocto/PetaLinux: Build throws errors when PREMIRRORS is set to downloads path for offline builds

https://adaptivesupport.amd.com/s/article/000033124?language=en_US

my solution

- mkdir: (only usefule when download from web??? IDK!) 
mkdir -p /impcas/cache/petalinux/sstate/downloads
mkdir -p /impcas/cache/petalinux/sstate/aarch64
mkdir -p /impcas/cache/petalinux/sstate/arm
- in `petalinuxbsp.conf`: (only usefule when download from web??? IDK!) 
DL_DIR = "/impcas/cache/petalinux/sstate/downloads"
SSTATE_DIR = "/impcas/cache/petalinux/2021.1/sstate/aarch64"
- in`pealinuxbsp.conf` (not tried yet) 
PREMIRRORS_prepend = " \
