Hi,

I have tried to port the FreeRTOS for LPC1857 controller. for the reference i have used port.c file of LPC1767 controller.

My problem is i have not seen any System Tick Timer configuration related information in LPC18xx data sheet. While in LPC17xx datasheet the separate chapter (LPC17xx System Tick Timer) is provided.

System Timer is main part to port FreeRTOS on LPC1857.

So any one have idea or already ported it on LPC18xx controller.

Following NXP's website the LPC1857 is still under development. Some samples are already available but that makes it difficult to really help you.

Can someone (NXP guru's perhaps) help us out here please?

My problem is that I don't see a datasheet ...
The NXP website does contain a page with the LPC1857 but it says the datasheet is not yet available.

The systick timer is part of the standard Cortex M3 configuration so I would expect the systick to be at the standard location where it is in all M3 devices. The feature list on the webpage does mention the systick timer so as I expected it is available.

If you've got target boards, just send me one so I can help you out with the port :D

I am also interested in such a target board :D

Edit: I just found the user manual UM 10430 and an evaluation board OM13039 (Keil MCB1857 Evaluation Board)

Since this is a KEIL development and this is an LPCXpresso forum....
