I tested the new firmware on a D8R-XP only, not on a D8RII-Plus. But as far as a close inspection of the board can tell, they're strictrly identical. D8R-II only has a slight difference that wouldn't affect actual operation (just the battery voltage and divider on the center pins for A1/A2), so the firmware should work on that too. D8R I don't know, never had one, but as the upgrade port is different there might be more hardware differences that could matter.

I'll upgrade all my receivers when I get to it, I just won't take them out of the models they're in just for that when I don't need CPPM on them anyway.

Both news are great. I think I will go ahead flash my D8RII+ to XP before it goes in the model.
Will come back if I have problem flashing it. ;)

But, Janekx, you see I do understand the Nerdish language a little better now. :lol: :lol: :lol:

OK, after dealing with my wheel encoder, I am ready to fool around with this upgrade. When read through Frysky's web site about which cable/s to use to upgrade, I got two very conflicting pdf directly from Frysky. May be you can clear this for me. One says connect the FUC-1 directly to the D8R-XP ( I assume this applied to the D8RII-plus as well). The other one says I 'MUST' connect the 'upgrade lite' in between the FUC-1/3 and the rx. Can someone clear this up for me. :?
I do have both FUC-1 and 'upgrade lite' but no FUC-2/3.

I think you don't need the ttl lite to upgrade the D8R II+

the upgrade lite was only for the old D8R. D8R-II and later don't need it, don't need to be opened, and don't have the little pads shown in the 3nd document anymore.

thank you. I will just use the Fuc-1 then.
one more question. what is the difference between Fuc-1 2 3 beside the connector and one more wire is solder on the 5V out?
Can I use Fuc1 and solder a wire from 5V out to upgrade the sensor hub in the future (if needed)?

You don't even need, you can just power the hub with the usual 2-pin cable from the receiver...

wouldn't it be easier, add a wire from 5v of Fuc-1 and does it all.
I am thinking make this Fuc-1 an easy plug and play thing to update all Frysky thing: module, rx, fld-02, sensor hub
if I add a 5v wire to where it is missing now I should get power to update the FLd-02 and the module (the plug fits those two)
then make an adaptor for the Fuc-1 plug to a small 4 pin plug to connect to sensor hub for update?
make a servo 3 wire adaptor for updating rx?

This way, one usb will be able to do all updating without any external power. You think this will work?

oops, change of plan - may be.
just plugged in the fuc-1 to PC USB. I checked the voltage on those 3 leads. the gnd and rxd actually is (+).
between txd and gnd is 5.9v between rxd and gnd is 0 volt between rxd and txd is 5.9 volt.
looks like it is already powered. the 5v line is only to power the fld-02 screen or sensor hub I think.
does that sound right? May be the 5v is not needed for updating, just make adaptors for rx, sensor will do it. the Flu-1 plug is good for fld-02 display already.

Just want to double check instead of add a 5V line in there and burn the display or...... ;)

Now here is another question.
I remember a while ago, Kilrah made a post about frysky rx cppm running at 18ms will have a problem if all 8 chs are running. It is proposed it would be better to extend that longer.
here is what I read: http://diydrones.com/profiles/blogs/frs ... -ftdi-cabl
It says the update is ONLY for D8R-XP and D4RII
so there is a fix for that 18ms thingy. Now since I am going to update the D8RII + to D8R-XP, why not update with this 27ms FW?

Well, you WILL upgrade with the 27ms firmware, as it's the only D8R-XP firmware that has been officially published you don't have much choice anyway ;)
Your FUC isn't powered, it's simply that the TXD signal is idle high while RXD is low. Supply would be 5V, not 5.9V.

Duh, just find that out 1 sec before your post they are the same FW. :oops:

But so what you are saying, if I want to flash the fW I need to add that 5V line? (for sensor hub and FLD-02 and rf module)
what about the rx has only 3 wire data line. just leave the 5v line out and power the rx with a BEC? or I can just route that 5v line to rx (+) pin? this way for rx, one adaptor with 4 wires from FUc-1 , 3 of them goes to rx data port, one 5v wire goes to (+) pin of rx.

Ok, will work on it. I may need to connect two dots on Fuc-1 to get that 5V connected. as of now that 5v spot is leading to nothing. will see, after I check with a voltmeter.

ha, never pay attention to those leds, all i know it is on or flashing. too small to tell other wise. ;)

OK, Glad to report back.
preliminary success of flashing the D8R-II+ to D8R-XP 27ms FW. ;)
servo works fine, telemetry works fine. and I DID get the cppm signal by connecting ch1 to my simulator plug and get stick response. :)
don't have a way to check RSSI signal though. any easy way to check that?

But there is a side effect: when I run cPPM mode, my wireless keyboard stopped functioning. 1st time ever. :lol:
Have to turn off Tx/rx to type again. (no issue when not running cppm mode, :? )

Hi, I just flashed my D8R-II plus with 27ms FW, and now it works fine with my FBL controller in cppm mode.
I also have an older D8R-II (no 'plus'), do you think I can flash it too ? The only difference with '+' seems to be A1 divider, am I wrong ?
