Re: Reg Linux-2.6.27 hang

Hi,
i tried enabling the EABI option in the kernel configuaration. Then also its hanging in the same place.
We are using /opt/freescale/usr/local/gcc-4.1.1-glibc-2.4-nptl-sf-1/arm-926ejs-linux/bin/arm-926ejs-linux- toolchain.

Note: We have Linux-2.6.19.2 kernel working with or without enabling EABI option in the Kernel. If we use working kernels rootfilesystem with our zImage it is
hanging at Freeing init memory.

We also checked that Baudrate is correct(115200n8) and serial console is configured correctly.
We are blocked here for almost 2 weeks. Are we missing any configurations????
Please help us in this regard.

Thanks and Regards,
Prabha

We built our own filesystem with same toolchain as above. With this we are getting error as follows:
