RS21 and Raptor Issue

Archive
1

Only when using a Power.Ext v1.0 module, RS21 and Raptor socket 11.

NOTE; Using socket 1 or 3 do not give this exception…

There are no loops in ProgramStarted()
The RS21 is initialized after using a button press.

The thread ‘’ (0x2) has exited with code 0 (0x0).
Using mainboard GHI Electronics FEZ Raptor version 1.0

RS21 works after all of the above.

Any comments?

@ willgeorge - I was able to reproduce the failure in UpdateInternalMacAddress, but the device recovered and successfully accessed the network. Can you post a small program that shows the rest of the exceptions?

@ John -

No other exceptions. Just what I posted.

This only happens during program start and yes, the RS21 works after that.

I posted only to show the behavior on only one particular socket (11). It does not occur when connected using sockets 1 and 3.

EDIT: I forgot to mention that I do not see this behavior when I am not using the PowerExt module. The DC power to the PowerExt is from a quality lab power supply.

@ willgeorge - This will be fixed in the next SDK.

@ John -

Thanks… Could you tell why only on socket 11…
I’m curious!

@ willgeorge - Initialization order in the driver was incorrect so it caused interrupts to fail. Socket 11 had a different default state than the other SPI sockets so you only saw it there.

Thank you for taking the time to reply.
