  1. I have recompile the kernel with THE modified .dts change the .dtb (which use the modified .dts) no change on the image (./u-boot-Digilent-Dev/tools/mkimage -A arm -T ramdisk -c gzip -d ./ramdisk8M.image.gz uramdisk.image.gz ) and no change to the BOOT.bin but this time ; RAMDISK: Couldn't find valid RAM disk image starting at 0.

  2. Hi all, After few weeks of searching on different websites, I have not find the solution and I can't finish the 'Embedded Linux® Hands-on Tutorial for the ZYBO' I am stuck in step 5.4, the booting of the kernel freeze I have a SD card with 2 partition (ZYBO_BOOT as vfat and ROOT_FS as ext4) I have nothing in ROOT_FS (it's normal? the tutorial do not say anything about it!) and 4 files (BOOT.bin devicetree.dtb uImage uramdisk.image.gz) see the terminal log through minicom ; U-Boot 2014.01-00005-gc29bed9 (Mar 03 2015 - 23:13:37) I2C: ready Memory: ECC disabled DRAM: 512 MiB MMC: zynq_sdhci: 0 SF: Detected S25FL128S_64K with page size 256 Bytes, erase size 64 KiB, total 16 MiB *** Warning - bad CRC, using default environment In: serial Out: serial Err: serial Net: Gem.e000b000 Hit any key to stop autoboot: 0 Device: zynq_sdhci Manufacturer ID: 2 OEM: 544d Name: SD02G Tran Speed: 50000000 Rd Block Len: 512 SD version 2.0 High Capacity: No Capacity: 1.8 GiB Bus Width: 4-bit reading uEnv.txt ** Unable to read file uEnv.txt ** Copying Linux from SD to RAM... reading uImage 3819368 bytes read in 368 ms (9.9 MiB/s) reading devicetree.dtb 7430 bytes read in 15 ms (483.4 KiB/s) reading uramdisk.image.gz 2608577 bytes read in 257 ms (9.7 MiB/s) ## Booting kernel from Legacy Image at 03000000 ...
