Plans for ecos on Nios-II?

Hello all!

I have two questions concerning the future plans for ecos on the Nios platform.

- Are there any plans to merge the Nios port back to the official ecos repository? On the ecos mailinglists there where some postings at the beginning of this year about merging the Nios port back to the official ecos repository. Is this still planned by Altera?

- Are there any plans to provide ecos-kernel awareness for the ported gdb? From our tests we could see that the Nios-gdb seems to be µC/OS-II aware, so that the current state of threads could be decoded. With ecos as RTOS this was not possible. Did we do something wrong here or is the gdb-port simply missing this feature for ecos?

Especially the kernel awareness would be a crucial requirement for proper productive use of the ecos-kernel.

Best regards,

Andreas.

    There are no immediate plans to incorporate thread aware debug into the Nios II IDE for eCos. However thread aware debug is possible using Redboot and insight (as described in the getting started instructions). If you'd prefer to use a JTAG rather than monitor based approach, then Lauterbach have a comprehensive kernel aware debug solution for eCos on Nios II.

    In principle the patch to incorporate the Nios II eCos port into the official eCos repository is still under review by the eCos maintainers. If you'd like further information, it would be best to inquire on the eCos mailing lists.
