uCLinux 2.6 based on Linux 2.0 kernel?

Hi,

Can anyone tell me if uCLinux 2.6 for the NIOS II is a derivative of the Linux 2.0 kernel? If not, which version of the Linux kernel was uCLinux 2.6 derived?

Also, since I'm familiar with the capabilities of uCLinux, I would like to know if it has any multitasking abilities. We currently have some software that runs on top of different version of Linux and has two applications running in different threads and I would like to know what the limitations are, if any, when using uCLinux 2.6 to implement multitasking applications.

We are interested in running uCLinux on the NIOS II in a Stratix II FPGA.

Any infornation would be appreciated.

Brad S.

    The latest uClinux 2.6.x for Nios II is based on Linux 2.6.9.

    Basically it has multitasking abilities, but you need be aware it does not have the system call fork, it has vfork instead. You can check uclinux website (http://www.uclinux.org).
