Ok i have now setup booted into the environment compiled with
OSELAS.Toolchain-2012.12.1/arm-cortexa9-linux-gnueabihf, mounted the other
system via nfs and tried to start any executable:
/mnt/bin/busybox: line 1: syntax error: unexpected word (expecting ")")
(thats with OSELAS.Toolchain-2013.12.2/arm-v7a-linux-gnueabihf on Altera SOC)
I have taken a look at both busyboxes and have run them through "readelf -e"
(attached). The only difference which sprung to my eye was the hardfloat
support, which i don't understand as both toolchains should be hardfloat
toolchains.
Starting the binary with strace gives:
execve("mnt/bin/busybox", ["mnt/bin/busybox"], [/* 11 vars */]) = -1 ENOEXEC
(Exec format error)
write(2, "strace: exec: Exec format error\n", 32strace: exec: Exec format
error
) = 32
exit_group(1) = ?
+++ exited with 1 +++
So i have an execution error and the shell error seems to be the shell
fallback from the kernel.
Another thing which caught my attention was the fact that:
objdump -d bin/busybox |grep UNDEFINED |wc -l
is 364 for the old and 13478 for the new toolchain.
Best regards
