Hello, I'm trying to use kexec on ARM. I'm using LEDE 17.01 with their ipq806x target on various boards of this type. I've followed many threads and a bit on the history of kexec on ARM because I'm running into a strange problem: root at LEDE:/tmp# kexec -d -t uImage --dtb=C2600-uImage.dtb --command-line="" -l C2600-uImage Try gzip decompression. Try LZMA decompression. lzma_decompress_file: read on C2600-uImage of 65536 bytes failed kernel: 0xb6d27010 kernel_size: 0x1eb76e MEMORY RANGES 00012028b6d27010-bea6aee700000004 (0) zImage header: 0x016f2818 0x00000000 0x001e5cd0 zImage size 0x1e5cd0, file size 0x1eb72e Could not find a free area of memory of 0x1edcd0 bytes...

I've compiled my own LEDE 17.01 image with the following LEDE options enabled: grep -i kexec .config CONFIG_KERNEL_KEXEC=y CONFIG_PACKAGE_kexec-tools=y CONFIG_KEXEC_TOOLS_kdump=y CONFIG_KEXEC_ZLIB=y CONFIG_KEXEC_LZMA=y I've also updated my local build to use kexec-tools-2.0.14 but always the same result. What else should I be looking at? Thanks! -- Kristian Kielhofner
