AT91RM9200 LINUX LITE

[tcpipchip]

Ola, inicialmente foi um LPC2138, mas...tive que melhorar o protocolo VT100 (achei um bug durante o uso do VI do LINUX)...e por falta de memória de programa, troquei pelo LPC2148.
Talvez eu faça um kit de baixo custo só com ele...um conversor serial para VGA padrao VT100.

O boot do linux vai ser a 19200,nao mais em 115200
O CHIPSET VGA tem muitas regras a seguirem (VT100)...o que está ocasionaldo overrun no recebimento dos dados...
Depois vou ver se aumento.
A versao 2.0 (correções esta indo bem, apenas 3 jumpers), provavelmene sai logo a 2.1
TCPIPCHIP

Só falta agora testes intensivos com o VGA CHIPSET...para certificar que tenha um comportamento idea de um TERMINAL BURRO VT100.
Hoje teste a entrada PS/2 do CHIPSET. Está perfeita.

A idéia é nao usar o PC para testar a placa...um custo a menos em um curso de linux embarcado....

Estou começando a ficar desesperado com o VT100....
VI, TOP, PS...

[tcpipchip]

VGA VT100 e PS/2 estão prontos!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Ultimos testes amanha com o MODEM GSM

legal! tá quase hein tcp!

parabéns!

[tcpipchip]

Tks!!!!

Sim, quase...são 6:55, vou dormir...

PS: vai ter que sair a versao 2.1....tem pesquenas correções agora...:(:(

[B-EAGLE]

pois é... vi um gato verde no canto direito inferior ali... heheh

[tcpipchip]

Operando agora somente com teclado ps/2 e VGA



Vou testar esta semana com a placa BLACKFIN (daugther) que montei...

[B-EAGLE]

tá usando qual distribuição?
boot em quanto tempo?

[tcpipchip]

VIAJEI...
É COLINUX QUE ESTOU USANDO COM A FAMILIA AT91SAM...

[tcpipchip]

Finalmente conseguimos compilar com python para o AT91SAM
# python
Python 2.4.2 (#1, Jul 1 2013, 16:23:47)
[GCC 4.2.1] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> print "hi asm51"
hi asm51
>>>
Agora sim....voce voce programar e C++ e Python no meu kit
Valeu Gadotti pela ajuda!

parece que agora tá 100%... ou falta alguma coisa tcp?

de qualquer forma, parabéns!!
