Update with generic CRUD

I'm using a generic CRUD developed by William F. Leite and it caters very well, but I'm having a hard time making a change, I tried some possibilities but without success, what I have is this:

// INSTANCIO A TABELA
$crud = Crud::getInstance($pdo, 'ubsSeq');

// BUSCO A ÚLTIMA SEQUÊNCIA DA TABELA
$sqlSeq = "SELECT max(valor) AS Sequencia FROM ubsSeq WHERE nome = 'seq_laudo'";
$arrayParamSeq = array();
$ResSeq = $crud->getSQLGeneric($sqlSeq, $arrayParamSeq, TRUE);

foreach ($ResSeq as $Seq) { 

    // ATRIBUO + 1 A SEQUÊNCIA RESGATADA
    $Seq = $Seq->Sequencia + 1;         

    // AQUI ALTERO O VALOR DA SEQUÊNCIA
    $arrayUp = array('Valor' => $Seq);  
    $arrayCond = array('Nome=' => 'seq_laudo');  
    $resposta = $crud->update($arrayUp, $arrayCond);    

}

The variable $Seq = $Seq->Sequencia + 1; has the correct value, but I can not do update , the attempt I made was to put quotation marks in the variable $seq because it will be stored in a varchar field, but also not It worked.
