From 408e2d5a224d8c62beae4cb1e7a3804abbbb123f Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?J=C3=A9r=C3=B4me=20Carretero?= Date: Wed, 16 Mar 2022 15:35:36 -0400 Subject: boot: image: fixup zstd decompression buffer initialization typo The code was mistakenly initializing the input buffer twice. Tested to be working on BeagleBone by adjusting CONFIG_SYS_BOOTM_LEN to 64MiB (probably works with less) and preparing uImage with: cat arch/arm/boot/Image \ | zstd --ultra -22 --zstd=windowLog=22 \ > linux.bin.zst mkimage -A arm -T kernel uImage -C zstd -d linux.bin.zst \ -a 0x80008000 -e 0x80008000 Without the windowLog restriction, bootm fails with a zstd decompression error 7 (window too large), which I haven't troubleshooted. There should be a bit more documentation on the feature...
