Hi Guys, I am seeing the same issue as Richard above. Was a solution ever found for this ESD reset issue?
In the past I have had some success on solving this issue on other micros by adding some capacitance on the micro's reset line to prevent the reset I/P bouncing when the ESD takes place, however looking at the BBB schematics, this is already included in the form of C24 being 1uF. Richard, did you find a solution to this? Gerald, I assume this family of processors must be used in many commercial products. Do you have an idea of what solutions were used to overcome this? Many thanks in advance. Lee. On Friday, 1 August 2014 18:57:39 UTC+1, Gerald wrote: > > CE testing that was does not cover ESD testing.
