[ECOS] Re: How to run ECO 3.0 on STM32

[kishore Srimat <kishorestp at gmail dot com>]

Hi John,

Thank you very much, Finally i could run Reboot.bin. I figured that I
need to change the  ecos HAL->Cortex-M Architecture->Cortex-M3 STm32
Variant->STM32 Eval Development Board HAL->Startup type= "ROM"

I need to change the startup type to "ROM" then it works. Default
value was RAM i guess. I could see the Redboot prompt in the serial
port.

Now I am trying to run Ecos, what is the easiest way to run Ecos ? I
got Keil and IAR debuggers and also Amontec debugger.

I have added applications  using Keil and IAR debugger into STM32. I
want to add these applications into Ecos aswell.

For example, I have HTTP server running  on STM32 with lwIP1.3.0. Now,
I know that Ecos does not provide lwIP 1.3.0. I have seen Simon
implemented lwIP 1.3.0 for Ecos, I could use that. before that I want
to first familiarize with Ecos environment by running different
examples. Please show me the direction what is the best path to reach
this goal.

Thanks
