I've been having a similar problem with the combination of a verdex and
NetWIFI-uSD boards to several other users on here; I have a Verdex XL6p,
which boots successfully when connected to a serial console via a tweener
board. However, when I connect the NetWIFI-uSD to the stack, the verdex
fails to boot and I no longer get any output on the console when the stack
is powered up (all hardware referenced here was purchased in December 2007).
After reading the other posts, I have confirmed that there is no significant
voltage drop (I'm seeing 5.14V with the NetWIFI-uSD board in place,
5.17Vwithout) on boot, that the NetWIFI-uSD is correctly seated and
(the LED lights up) and that there is no link light on the ethernet port
when connected to a switch.
I'm at the point of RMA'ing the two boards I have, but as I'm relatively
green when it comes to both linux and Gumstix, it seemed sensible to ask a
few questions here first:
- It seems from other posts as if there are a faulty batch of NetWIFI-uSD
boards, if this is the case, is there any way to identify which boards are
affected or test if my boards are from the faulty batch? Both of mine appear
to be from the same batch.
- On the docwiki, there is mention of ensuring that the correct buildroot
version is used. I'm only at the stage of trying to boot the image shipped
on the verdex and I'm working on the assumption that I should at least see
u-boot output on the serial console, irrespective of the buildroot version.
Is this where I'm going wrong and do I need to reflash the verdex before I
have any chance of getting the NetWIFI-uSD to work?
- One of the previous posts states that there may be a compatibility problem
between the verdex/tweener/NetWIFI-uSD, is this a problem? From what I
understand about the boards and the 120/60 pin connections, I can't see why
this should be the case, but as mentioned above, I'm still at an early stage
on the learning curve!
- Am I missing something really simple? I've checked power, connector
seating and alignment and tried all possible permutations of the two verdex
and two NetWIFI-uSD boards that I have.
Thanks in advance for your help,
