ERROR: EEPROM verify failed

I am getting the following in the terminal when attempting to flash a P8X32A-D40.

proploader.mac -k -D baud-rate=115200 -p /dev/cu.usbserial-P97z9aa5 "~/pixelmusic3000e.binary" -e

Hi Levi, That's an unusual error. If you've wired up your P1 yourself, make sure to follow EEPROM connections like shown in this diagram. If you did wire it yourself, most likely this is a case where something isn't connected as recommended. If you are using something like a Propeller FLiP or some other board that already includes a P1 + EEPROM, then most like the problem is something else, including the possibility that the EEPROM is actually bad or worn out, in which case you'll need to contact ***@***.*** to request an RMA and replacement. [image: image.png] The fact that it downsteps the baud rate first means that it's having trouble communicating with the Propeller, so perhaps it's a board (or self-wired unit) that doesn't have a fast Crystal attached? (ie: it's using the internal fast RC Oscillator only). That could also be caused by a poor-quality USB cable; some don't have very good shielding and may allow for a lot of communication noise. *Jeff Martin, R&D + IT* 916.625.3002 ***@***.*** www.parallax.com and learn.parallax.com [image: See Sale Details] <https://www.parallax.com/parallaxs-microbit-shop-is-a-one-stop-source-for-curriculum-and-hardware/>
