Thanks Laurentiu - I did validate that the interp section looks to be 0x1000 bytes for the qemu-* binaries: $ /usr/local/oecore-x86_64/sysroots/x86_64-oesdk-linux/usr/bin/qemu-system-arm --version QEMU emulator version 1.6.1, Copyright (c) 2003-2008 Fabrice Bellard $ readelf -S /usr/local/oecore-x86_64/sysroots/x86_64-oesdk-linux/usr/bin/qemu-system-arm There are 29 section headers, starting at offset 0x5a14b8: Section Headers: [Nr] Name Type Address Offset Size EntSize Flags Link Info Align [ 0] NULL 0000000000000000 00000000 0000000000000000 0000000000000000 0 0 0 [ 1] .interp PROGBITS 0000000000000270 00000270 0000000000001000 0000000000000000 A 0 0 1 [ 2] .note.ABI-tag NOTE 0000000000001270 00001270 0000000000000020 0000000000000000 A 0 0 4 [ 3] .note.gnu.build-i NOTE 0000000000001290 00001290 ... If anyone has any other suggestions to test, I will gladly attempt them before posting a v2. Cheers! -Chris
