Having read the thread posted here, I have the same problem as "tiagopadua" (of May 10, 2013) His issue was fixed by loading the firmware via a Windows PC.
I need to flash the 9XR via a Mac. Not a Mac running Windows, but a Mac.
I've tried several combinations of OpenTx with Campanion9x, eePe, and er9x with each of those. My 9Xr is very new and has the m128 chip, I strongly believe, based on the messages I get. I have experience flashing a FrSky with er9x and eePe, on my same Mac, so I wonder what's going on. Perhaps it's solely related to the 128 chip and my software configurations.
Can anyone offer up a sure fire way to flash a 9XR, with a 128 chip, using solely a Mac? I mean a really clear way to proceed.
Thanks greatly. I've been in RC for 25 years, but am just trying out opensource transmitters and software. The FrSky worked fine, hoping to get a 9XR up and running too...
