...but it won't tell you if your drivers are flakey because they are too weak to drive your cable, which is really my point Sure - you can't beat using a scope and seeing what's really happening! However, If you do the full loopback by shorting the processor pins on the target board, that includes the cable. But, without a scope, you can't tell if it's working well or just by the skin of its teeth. |
