Re: Buildroot compile error

Did you read link I provided above? You compiled your buildroot with toolchain with disabled "large file support". Now you set this parameter in buildroot config but your toolchain is already compiled. You should rebuild toolchain in your buildroot. Delete 'toolchain_build_arm' folder from buildroot...

Re: ttySAC0 issue on 2.6.31 after real time patch

I got some free time and dug into problem with ttySAC0 console. I applied patch-2.6.31.5 and patch-2.6.31.5-rt18 on 2.6.31 linux kernel from Buserror repo and after tracing kernel console function calls I realised that the reason why linux works so slowly on console is busy loop on 71 interrupt risi...

Re: /bin/hostname: not found

If you use Busybox on your Mini2440 you should make symbolic link 'hostname' to /bin/busybox:

Code: Select all

ln -s /bin/busybox /bin/hostname
