This was an estimate I was given to do an RTEMS BSP for the motorola 6600.
Does anyone else have any experience/estimates for this type of work?


Don't forget that this board features a central chip (hostbridge, memory controller,
interrupt controller, networking IFs, serial IFs, +...) for which no documentation is
publicly available! (Either you have to sign a NDA and work out all the legal implications
or work from indirect info [linux, vxworks headers etc.])

For which system does it take 4 months?

I agree with Jun-ichi that the real issue is the availbility of BSPs. There is appromately a 4 month investment to create a new BSP.

Hi, all;

Let me explain "our work on ITRON" again in my words.

The goal of the work is to achieve what we call "Embedded EPICS", I mean, running EPICS directly on many different types of front-end controllers.
However, this scheme apparently has one serious difficulty.

Can we afford to create BSPs for each of the controllers by ourselves?
The answer is definitely NO.

Fortunately or unfortunately, we observed that a specific product of RT-kernel seems to be dominating the Japanese market due to its no-runtime-license feature.
We thought that if BSPs are available on the market and if we share the development environment with those companies, the difficulty in achieving "Embedded EPICS" might be solved. And, the product of RT-kernel happened to be a uITRON.

What matters is not ITRON but availability of BSPs and a development environment for them at a reasonable price.
