Nucleus Porting to ASIC based on ARM926EJ-S

Started by bhaskar March 27, 2006
Dear All,

I have plans to work on ASIC based on ARM926EJ-S core. I am planning to
port the Nucleus RTOS to the ASIC.

I find the ARM core is well supported in the Nucleus RTOS.

How to analyze the porting requirements to a supported processor but
for different set of peripherals?

I have downloaded the NucleusSIM from the site. Can this be useful to
me understanding the HAL layer along required porting considerations?

Are there any specific Nucleus Porting support groups for ARM?

Regards,
Sandeep.

By design, Nucleus does not usually support peripherals beyond the timer used to generate the system tick. You will likely not find much in the way of porting support, because Nucleus is not free software; it is the property of Accelerated Technology, a division of Mentor Graphics, and may not be used in a product or ported without a license purchased from them. --Gene
Dear Gene,

I understand Nucleus is not a free RTOS.

We are even planning to get the License in a while.

Nuclues already supports ARM926EJ-S core.

Before getting the License, I just want to analyse the porting
requirments of Nucleus RTOS to a different ASIC with the same ARM core.


For that, I need to understand whether Nuclues supports HAL layer to
make the porting easy.

If not, what would be involved in porting it?

It's not clear what you mean by HAL layers. A HAL layer to what?

It's a long time since I did it, but the only thing that you need to get working is the interrupt and the memory management. And this is done for you. Nucleus should run out of the box an an ARM, what is it you think won't run? tim
