ARRIA 10 U-Boot boot from QSPI - spi probe failed - ARRIA 10 U-Boot boot from QSPI - spi probe failed Hi, I use with arria 10 dev kit and followed the tutorial Arria_10_SoC_45_Boot_from_QSPI I prepared system for baremetal and skipped the sections to prepare: kernel.itb - Linux kerned and device tree core-image-minimal-arria10-rootfs.jffs2 -Linux rootfs Than I programed: cd $TOP_FOLDER/qspi_bin ~/intelFPGA_pro/20.4/nios2eds/nios2_command_shell.sh \ quartus_hps -c 1 -o e ~/intelFPGA_pro/20.4/nios2eds/nios2_command_shell.sh \ quartus_hps -c 1 -o pv -a 0x0000000 u-boot-splx4.sfp ~/intelFPGA_pro/20.4/nios2eds/nios2_command_shell.sh \ quartus_hps -c 1 -o pv -a 0x0100000 fit_uboot.itb ~/intelFPGA_pro/20.4/nios2eds/nios2_command_shell.sh \ quartus_hps -c 1 -o pv -a 0x0300000 fit_spl_fpga.itb As the result I get a "spi probe filed": What is the problem? What it does mean? BTW, I followed boot from SD card instructions (also for baremetal - without kernel and rootfs files) and success to boot.

My dev kit booted to u-boot and the kernel. Mike
