Hi, I have met an issue during loading a new kernel with Kexec on an ARMv5 SoC. The kernel is a 4.19 with Gzip compression but during loading Kexec does not recognize the compression. If I load the new kernel and dtb with: kexec -l /boot/zImage -d --dtb=/boot/u-boot.dtb The output is: Try gzip decompression. Try LZMA decompression. lzma_decompress_file: read on /boot/zImage of 65536 bytes failed kernel: 0xb6a68008 kernel_size: 0x494d30 MEMORY RANGES 0000000000000000-000000000fffffff (0) zImage header: 0x016f2818 0x00000000 0x00494d30 zImage size 0x494d30, file size 0x494d30 kexec_load: entry = 0x8000 flags = 0x280000 nr_segments = 2 segment[0].buf = 0xb6a68008 segment[0].bufsz = 0x494d30 segment[0].mem = 0x8000 segment[0].memsz = 0x495000 segment[1].buf = 0x1fcf060 segment[1].bufsz = 0x245b segment[1].mem = 0x16f2000 segment[1].memsz = 0x3000 Looking at the debug, the function gzdirect returns “1” which indicates the kernel compression is not of gzip but I definitely use gzip. I also tested it with LZMA compression and uImage instead of zImage but all with the same outcome. To be complete, I use Kexec-tools 2.0.19 and zlib 1.2.11. Did I implement something wrong or how can I debug this further? Kind regards, Maikel Coenen _______________________________________________ kexec mailing list kexec@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/kexec
