Enviado por Sergio Prado (sergio·pradoΘe-labworks·com):

“Por um bom tempo, durante o desen­volvi­mento do ker­nel Linux, os desen­volve­dores sen­ti­ram falta de uma boa e menos intru­siva inter­face de debug­ging. Foi só na ver­são 2.6.26 que o kgdb foi aprovado e entrou no mainline.

A ausên­cia de um mecan­ismo de deb­bug­ing é ainda mais sen­tida quando pen­samos no desen­volvi­mento embed­ded, prin­ci­pal­mente no tra­balho de desen­volvi­mento de porte do boot­loader ou do ker­nel para out­ras platafor­mas. E é aí que entra a inter­face JTAG.

Neste artigo estudaremos o procedimento de debugging do kernel Linux através de uma interface JTAG.” [referência: sergioprado.org]
