| Oct 19, 2015 at 11:28 | comment | added | PlasmaHH | The answer to "could have damaged" is almost certainly always "yeah, it could have" ... You say this is your own board, maybe the board itself is wrong too? Since this is not a collaborative debugging service where we go forth and back, providing every information up front is essential to have a small chance of the question being answered and not closed (schematics, board layout, scope traces etc.) | |
