What about putting the notes section into the read only segment, i.e. the ROM? .config is attached. It's against 3.6.10 + some patches. The problem does not occur with our uclibc based toolchain, which doesn't crate a .notes section, but it still happens with a newlib based one. > ${CROSS_COMPILE}gcc -v > Using built-in specs. > COLLECT_GCC=/home/mol/vcs/OSELAS.Toolchain-2011.02/inst.keep/opt/OSELAS.Toolchain-2011.11.0/arm-cortexm3-eabi/gcc-4.7.2-newlib-1.19.0-binutils-2.22/bin/arm-cortexm3-eabi-gcc > COLLECT_LTO_WRAPPER=/home/mol/vcs/OSELAS.Toolchain-2011.02/inst.keep/opt/OSELAS.Toolchain-2011.11.0/arm-cortexm3-eabi/gcc-4.7.2-newlib-1.19.0-binutils-2.22/bin/../libexec/gcc/arm-cortexm3-eabi/4.7.2/lto-wrapper > Target: arm-cortexm3-eabi > Configured with: /home/mol/vcs/OSELAS.Toolchain-2011.02/platform-arm-cortexm3-eabi-gcc-4.7.2-newlib-1.19.0-binutils-2.22/build-cross/gcc-4.7.2/configure --build=x86_64-host-linux-gnu --host=x86_64-host-linux-gnu --target=arm-cortexm3-eabi --enable-multilib --with-float=soft --with-fpu=vfp --with-cpu=cortex-m3 --with-mode=thumb --with-newlib --disable-__cxa_atexit --enable-sjlj-exceptions --disable-nls --disable-decimal-float --disable-fixed-point --disable-win32-registry --enable-symvers=gnu --with-pkgversion=OSELAS.Toolchain-2011.11.0 --enable-threads=single --with-system-zlib --with-gmp=/home/mol/vcs/OSELAS.Toolchain-2011.02/platform-arm-cortexm3-eabi-gcc-4.7.2-newlib-1.19.0-binutils-2.22/sysroot-host --with-mpfr=/home/mol/vcs/OSELAS.Toolchain-2011.02/platform-arm-cortexm3-eabi-gcc-4.7.2-newlib-1.19.0-binutils-2.22/sysroot-host --prefix=/home/mol/vcs/OSELAS.Toolchain-2011.02/inst/opt/OSELAS.Toolchain-2011.11.0/arm-cortexm3-eabi/gcc-4.7.2-newlib-1.19.0-binutils-2.22 --enable-langua ges=c --enable-c99 --enable-long-long --enable-libstdcxx-debug --enable-profile --disable-shared --disable-libssp --enable-checking=release > Thread model: single > gcc version 4.7.2 (OSELAS.Toolchain-2011.11.0) Here the readelf output: ROM starts at 0x0 RAM starts at 88008000 > Section Headers: > [Nr] Name Type Addr Off Size ES Flg Lk Inf Al > [ 0] NULL 00000000 000000 000000 00 0 0 0 > [ 1] .bootloader PROGBITS 00000000 008000 000300 00 AX 0 0 8 > [ 2] .head.text PROGBITS 00000300 008300 00004c 00 AX 0 0 4 > [ 3] .text PROGBITS 00000360 008360 077844 00 AX 0 0 32 > [ 4] .text.init PROGBITS 00077ba4 07fba4 00009c 00 AX 0 0 4 > [ 5] .rodata PROGBITS 00078000 080000 00d9c8 00 A 0 0 32 > [ 6] __param PROGBITS 000859c8 08d9c8 0000a0 00 A 0 0 4 > [ 7] __modver PROGBITS 00085a68 08da68 000598 00 A 0 0 4 > [ 8] .ARM.unwind_idx ARM_EXIDX 00086000 08e000 000040 00 AL 3 0 4 > [ 9] .init.text PROGBITS 00086040 08e040 006b28 00 AX 0 0 8 > [10] .exit.text PROGBITS 0008cb68 094b68 0001f0 00 AX 0 0 4 > [11] .init.proc.info PROGBITS 0008cd58 094d58 000054 00 AX 0 0 2 > [12] .init.arch.info PROGBITS 0008cdac 094dac 000044 00 A 0 0 4 > [13] .init.tagtable PROGBITS 0008cdf0 094df0 000040 00 A 0 0 4 > [14] .init.data PROGBITS 0008ce30 094e30 000388 00 WA 0 0 4 > [15] .data PROGBITS 88008000 098000 012aa0 00 WA 0 0 256 > [16] .notes NOTE 8801aaa0 0aaaa0 000024 00 A 0 0 4 > [17] .bss NOBITS 8801aae0 0aaac4 005414 00 WA 0 0 32 > [18] .comment PROGBITS 00000000 0aaac4 000028 01 MS 0 0 1 > [19] .ARM.attributes ARM_ATTRIBUTES 00000000 0aaaec 00002b 00 0 0 1 > [20] .debug_line PROGBITS 00000000 0aab17 098048 00 0 0 1 > [21] .debug_info PROGBITS 00000000 142b5f 88b2f3 00 0 0 1 > [22] .debug_abbrev PROGBITS 00000000 9cde52 06a5dc 00 0 0 1 > [23] .debug_aranges PROGBITS 00000000 a38430 003b20 00 0 0 8 > [24] .debug_ranges PROGBITS 00000000 a3bf50 0296e0 00 0 0 8 > [25] .debug_frame PROGBITS 00000000 a65630 025388 00 0 0 4 > [26] .debug_str PROGBITS 00000000 a8a9b8 03ef39 01 MS 0 0 1 > [27] .debug_loc PROGBITS 00000000 ac98f1 169767 00 0 0 1 > [28] .shstrtab STRTAB 00000000 c33058 000141 00 0 0 1 > [29] .symtab SYMTAB 00000000 c33674 03bf70 10 30 11065 4 > [30] .strtab STRTAB 00000000 c6f5e4 0205da 00 0 0 1 I can put the kernel patches and the toolchain on our ftp for download.
