Even if there's no ready-to-use JTAG port on the board on the PCB there sure will be a site where you can add a pin header or box header (requires some soldering). From there it should be straight forward. Identify the site (ARM JTAG comes in 10- and 20-pin varieties)and pinout, then connect to your JTAG board/box. I have tried that with a bricked Patriot NAS that used a Marvell 88F5182. The device didn't have a serial port nor JTAG but both facilities had been thought of on the PCB. Now it has serial console and can be un-bricked at will. P.S. Other two replies show Marvell has been more considerate than Patriot. --On Sunday, January 16, 2011 14:41 -0500 erik quanstrom wrote: > On Sun Jan 16 14:38:27 EST 2011, eris.discordia@gmail.com wrote: >> Is it configured to use a serial console?
