O conector de 6 pinos logo abaixo do chip de RAM é o conector de debug. Esse conector é usado para ter acesso ao “terminal” do linux embutido, usando um conversor RS232-TTL. O principal propósito é poder instalar um novo firmware quando algo der muito errado e o aparelho ficar inoperante. Você pode obter um plug para esse conector (6 pinos, passo de 2mm) em uma grande variedade de DVD players. Ele está presente principalmente na conexão entre a placa CPU e o drive. O Proview DVP-801, por exemplo, tem internamente quatro cabos com plugs compatíveis .

Atenção: você só precisa mesmo dos pinos RX, TX e GND. O +3.3V só é necessário se você precisar alimentar o cabo de comunicação usando a fonte do S9, mas isso só deve ser feito se você souber o que está fazendo.  Conectar o +3.3V pela razão errada pode levar à queima do seu S9, do seu cabo, ou da porta de comunicação no seu computador.

Em geral, se você trocar a posição de RX e TX, não tem importância. Basta inverter e testar de novo. Nunca vi uma porta de comunicação queimar por isso.

Você pode usar o Hiperterminal para visualizar o boot. Configure a porta para 115200 8-N-1.

Com o aparelho parado, a mensagem “watchdog test pid 199, threshold: 50″ é repetida a cada 2 segundos. O valor de pid pode ser diferente no seu caso, mas sempre se refere ao processo “dvdplayer”. Por exemplo, procurando por 199 na lista de processos rodando você veria:
199 root 786m S < DvdPlayer

É possível entrar no modo interativo pressionando ESC logo no início do boot (veja a linha 23 do log). Eu testei isso com o Hyperterminal e não funcionou de jeito nenhum (o Hyperterminal fica é travado por alguns segundos), mas com o Putty e o Tera Term funciona na primeira tentativa. Com o programa em primeiro plano, mantenha a tecla ESC pressionada e ligue o S9.  Se você fizer corretamente o boot se resumirá a isso:

Como forçar a instalação do firmware usando a porta serial.

No prompt do terminal, digite esses comandos:

Realtek> erase -m [ENTER] (o aparelho responderá com “/done”)

Realtek> reset [ENTER]

Isso irá apagar toda a memória do aparelho, exceto bootloader. O que forçará o bootloader a buscar um novo firmware nas portas USB. Basta inserir um pendrive em uma das portas USB (testei em ambas) com o firmware (arquivo install.img) na raiz. Quando o aparelho detectar o firmware, exibirá uma tela mostrando a instalação. Enquanto o firmware não for localizado o aparelho parecerá estar travado exibindo o logo inicial. Mas pela porta serial você poderá ver que ele está em atividade, procurando o firmware.

O conversor TTL-RS232

Se você não sabe como obter um conversor TTL-RS232, leia minha página sobre recuperação de players Mediatek. O cabo usado é exatamente o mesmo. Mas certifique-se de que o cabo usado tem saída de 3.3V, porque apesar dos chips MT13x9 comprovadamente tolerarem saídas de 5V, é melhor não arriscar com o S9. Por exemplo, caso você use este esquema, certifique-se de usar o chip MAX3232:

Assim como no caso dos players MT13x9. a porta serial dos aparelhos Realtek é ligada diretamente ao chip, sem buffers. Se você fizer uma besteira poderá inutilizar a CPU do aparelho.

Por não ser necessário transferir grandes volumes de dados pela serial (para instalar e ler firmware se usa a USB ou o HDD), a conexão serial da Realtek é muito mais fácil de estabelecer. Cabos USB de celular que seriam problemáticos em um projeto MT13x9 devem funcionar perfeitamente em um projeto Realtek.
