Re: AT91SAM9263-EK or similar

[Mario Trangoni <mjtrangoni@gmail.com>]

Hi Martin, thanks for your answer. I
 tell you that I'm working on a free operating system at a designed plate (with AT91SAM9263) that has already a proprietary Linux (jjf2root filesystem), which boots with 
U-Boot and loads it from a flash memory (NAND 1Gbit), 16MBit SRAM, 64 Mbyte SDRAM. It has no ethernet connected to the outside, just one USB Host and one device. There's one TFT-LCD 320x240 and one Touchscreen via serial connection. 

I've many ideas in my head, but i dont realized who is the best.

1) To work with a USB PenDrive and normal Debian squeeze like you said with emdebian kernel.

2) To compile a system with Buildroot (that seems to go well with flash memory).

Waiting to hear your opinions!

I want to ask to the list members if someone has worked yet with an Atmel
AT91's project. I have to choose one OS to make a card terminal module.
It has one LCD display, one touchscreen keyboard, RFID module, 2 USB port
connected (one device and one host) and one serial connection to send the
information.
The Idea is at the beginning just choosing one open source operative system,
and after that to work with Hardware's drivers, etc.

I'd like to get in contact with people who are currently working with a
similar system

Hola Mario:

we are working on a device with an AT91. It features a
non-standard LC display, custom keys, USB etc.

As operating system we use standard Debian Squeeze - even
if it is not yet released. We tried also Emdebian, but
saving disk space is not currently not an issue for us,
so we changed to mainstream Debian.

We use the armel cross compilers from the Emdebian project,
which save you the work of creating the toolchain. Nice!

The kernel is 2.6.35, from which we build a Debian kernel
package for our device.

Main questions to consider for you:
 - How much RAM do you have?
 - How much flash or disk space?

Salu2, Martín
