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! Regards, Mario Trangoni 2010/12/7 W.
