AT91RM9200 LINUX LITE

[tcpipchip]

Agora so falta fazer a placa v2.1, hoje eh a 2.0, que tem 4 jumpers. Tambem na 2.1 vou remover 16 resistores.
E as bibliotecas estao 100%. Eclipse ok,jtag ok,drivers ok,usb ok, modem ok,vga ok,ps2 ok,mmc ok, ethernet ok, usb ok, usb device ok, rtc ok,speaker ok, enfim, tudo ok
Tks

Qual o objetivo da placa? Aprendizado somente? eu gostaria de ouvir de pessoas que estão colocando linux embarcado o porque desta necessidade.

Qual RTC usou? Está atrasando muito?

[tcpipchip]

É um Starter Developer Kit...

O relógio é um integrado no modem...e não está atrasando....

[tcpipchip]

Comecei a fazer um exemplos em python para acessar os IOCTL.

[tcpipchip]

Vou tentar porta o DEBIAN para minha placa...
São 512Mb com o FILESYSTEM
Vamos ver no que dá...

[tcpipchip]

Não tá fácil...demorou...mas saiu...para o OPEN-WRT...
Não sei até que ponto vale a pena ter o LINUX...

Realmente estou gostando mais do OPEN-WRT do que o DEBIAN
