Compatible DEVO 6 Receivers ?????????

Here are the compatible receivers for the DEVO 6 transmitter.

RX-701 receiver, 100% compatible.

RX-801 receiver, old firmware are not compatible.

RX-801 receiver, newer firmware 100% compatible.

RX-802 receiver, 100% compatible.

If you plan on buying more receivers for the DEVO 6, buy the RX-701 or the RX-802.
The RX-802 has the coax antenna's, these are great for carbon fiber models.
If you buy the RX-801 your playing the lottery on if it has old or new firmware.

Hope this helps DEVO 6 owners.
NOTE: all the above mentioned receivers work with the DEVO 8.

These DEVO's are too cool.

Other than the antennas how is the RX802 different than the RX801? What's the advantage of the antennas over the ones on the RX801?

It has telemetry, ie it is transmitting too, that is the larger antennas for...

Thanks. Waiting for things you need is very aggravating. Hope it arrives soon.

Well, I've got my Devo-8 and STLink/V2 now. I'll be playing with it tonight, and hopefully will have something to report out soon.

Unfortunately, I immediately hit a road-block...
The ST-Link software can see the STM32F103VCT6, but I immediately get this:
Code:
19:06:59 : Cannot read memory!
                  Disable Read Out Protection and retry.
19:09:28 : Connected via SWD.
19:09:28 : Device ID:0x414 
19:09:28 : Device family :STM32F10xxx High-density device
19:09:28 : Cannot read memory!
19:09:29 : Connection to device is lost!
19:09:30 : No target connected
It doesn't stay connected long enough for me to be able to be able to do anything else
I don't really know much about the STLink or the memory-protection available in these processors, so I'll likely do some reading on that and see what options we may have.

Here is a bit more info:
The relevant section about protection is section 2.4 of the Programming manual (PM0042)

This discussion contains some interesting info regarding read-protection.

If we want to start from scratch, it should be trivial to mass-erase the Flash memory and reset the read-protect bit, but since we don't have many of the pages, it wouldn't be possible to flash back, so this isn't a good idea until we've dumped the original ROM.

Since we CAN write to the ROM at 0x08004000 via SFU, and even with the read-protect-bit set, code can access ROM when not in DEBUG mode, it will likely be pretty easy to write a function to dump the ROM (probably out the SWD pins since they are easily accessible) and load that code via SFU. We need to find an entry point where we can put the code, and it'll definitely slow things down, but I don't see the RDP as a show-stopper (though it may make my stlink less useful (and my logic-analyzer more useful).

It does however mean I won't have time to work on this much for the next several days.
