[Gumstix-users] Reflash verdex using JTAG

[Christoph W. E. Z. <wa...@ti...>]

Hi all,

I need to reflash a Verdex Pro XL6P using JTAG as the bootloader is
corrupted. I have a JTAGpro board and an Olimex ARM-USB-TINY JTAG
interface. I also installed openocd version 0.3.1 from the package
repositories for Ubuntu 10.04.

I wanted to proceed according to the wiki (
http://docwiki.gumstix.org/index.php/HOWTO:_Reflash_using_JTAG_and_OpenOCD
) but the config and script files provided there don't run as they are
written for an older version of openocd. I then tried to adapt them to
the used openocd version but did not succeed as the JTAG connections
fails with the following error messages:


Error: JTAG scan chain interrogation failed: all ones
Error: Check JTAG interface, timings, target power, etc.


Has anyone managed to reflash a Verdex using the described setup and
could provide me with the steps needed to do so?

Thanks and best regards,
Christoph
