Hi,
I am in search of lowest cost but with good linux BSP support for an embedded web-server solution. The solution must support both Ethernet and Wi-Fi.
The Wi-Fi must support both Adhoc and Infra-structure mode of network.
My Hardware should have following features:
1. UARTs
2. SPI (for Wi-Fi)
3. USB (for Wi-Fi)
4. Boot from SPI flash or uSD
5. Ethernet Interface
6. Some GPIO pins
7. Assume there is no color or graphic display.
I have narrowed down my search to Atmel AT91SAM, but dont know how it compares with other solutions by other ARM chip vendors such as:
NXP LPC Series,
FREESCALE MK60 Series,
ST Micro STM32 Series.
I am looking for an ARM microcontroller for which there is free embedded linux support (Reference Designs, Free Linux OS, BSP, Drivers, Code examples etc).
1. Do you think i can find an ARM-Linux solution where i can run linux from on chip flash (lets say 512k) and on chip RAM (lets say 128k) and can still run fully working embedded webserver on ethernet and Wi-Fi interfaces?
2. How much minimum RAM and Flash would be needed for running an embedded Linux and web-server on both ethernet and Wi-Fi interface?
3. I would appreciate if people share their experience with low cost arm chips they have used.
Regards
