Feb 4, 2013 at 22:56 | comment | added | Chris Stratton | Yes, it's easy to imagine that the current needs could spike. You could try adding local capacitors right at the socket. However, it's also possible that your SPI timing is almost on the verge of failing setup time in general, and this one case exposes the problem. | |
