I'm getting the common "verification error" when trying to download a program to my PICAxe and I'm looking for assistance. I'm trying to program the little 08M2 surface mount servo module using an AXE027 download cable. I recently bought everything from Robotshop, so it should all be legit parts and not bootleg.
I've done a bunch of searching here on the forum and understand that most of the problems are power supply related, and with that in mind, I've already put additional capacitance in place with no effect. I'm powering the module with a powered breadboard power supply which should have plenty of oomph and I've placed both large (330uF) and small (.22uF) caps right where the board plugs into the breadboard. The SMT servo board also comes with a small ceramic SMT cap soldered right next to the PICAxe chip.
I've scoped the communications lines and the waveforms (with an old non-storage analog) scope. Voltage levels look good, and as best as I can tell without storage, the signals look clean.
I've also tried plugging the AXE027 cable into all of the different USB ports on my machine. No change.
Here's a couple pics of the problem(s). Here's what happens when I download a program. The byte number for the error location jumps around, but I can't get a full clean download:
I get the same error just trying to erase the part:
