Devo Loader. Now working Fully

this is just files needed to use loader+ hex.
You'll have to give me while to sort my edits to code. I use IAR ide, free version but could done using codewarrior lite.

i'm guessing serial loader would work without the need to alter Boot pins and Reset, Hold backdoor button and update simples.

Only downside to this is that its windows only.
Now had a thought about that.

OpenBTL does have other ways it can work, update from flash. Deviation has USB built in all ready and not OS dependent. So what if we could use that instead. And with other Devo Tx's there so much more flash free so make boot area larger if needed and run it so we have option to load different Dev builds and go back to release build at will. Rename 'Protocol' folder to reflect Build number or keep folder for stock setup plus Dev folder. Maybe it could even be away round 7e limited space, remove options as needed but go back when needed.

Now I don't know if this is even doable but I see in Deviation code that bootloader can be deleted. Could deviation be used to replace loader so no need to open Tx or need any extra hardware.
But would mean no going back to Stock Walkera which I know would be a shame.

Oh I wouldn't be able to do any of that Hey I'm shocked I got this far.

Spent a night trying to elicit response from System Memory bootloader on Devo7E - no success at all.

Theoretically, you just need to connect BOOT0 to VDD - there is a conveniently broken out header inside of Devo - 2-pin 100 mil between plated holes - just between SWD header and RF module.

I had serial loader working but it was very hit or miss, why I was glad I bought STlinkv2 don't have to worry about boot 1/2. And if you going to buy one chose one of ST Discovery Dev boards there's one on there and there so very cheap. Friend bought me F3Discovery and out the packet you have cheap Openpilot FC + STlinkv2.

Phil,

How did you circumvented the software shutdown issue ?

You save the model before shutdown, I would rather not have to implement the power up/down circuit.

But just in case, I know PB posted a schematic some time ago, do you happen to have a link for it ?

Thanks

Still think just a 'NO' button Yeah ultra high tech.

Devo10 power circuit can't put my finger to it this sec. When I get to it I'll add it to my eagle circuit and sorry Kicad not happening.

I've been looking at circuit for WK29-2801 and still think this could be very low part upgrade all be it few meters of wire. Will need to replace 16k flash.

I have installed Eagle just for that.

But still say "Eagle sucks ", very low part I can fly with that, niarf.

I'm hoping for a favor from a few people.

Up till yesterday I've been using Rugwarriors build of MinGW DeviationTX and very happy works fine. Until the limited space on 7e showed its face and different builds/Os gave different size code. So I tried sbstnp VM and worked out great and fixed something I still don't get why but I've no idea even how I'm to edited code in there.
So the favor if anyone can using windows mingw could you compile devo7e and convert elf to Srec Please ? OBJCOPY -Osrec devo7e.elf devo7e.srec. I'm hoping my install is just broken though I have tried many combo's today and can even compile to 115.86k. But loader does not like it at all but code works when loaded other ways.
Also I'm wondering even if mine is just one off broken install that I should be using same tool chain as Pb just to be on same page/results?

Thanks, Phil

Give the PDF a read, the VM is sharing a folder with the host so you basically can use your favorite Windows editor for code editing (or learn vim, but I guess that's out of the question ))

Shoot me a PM if you have other questions.

My board is on his way :

Even cheaper than DX and faster to

Looks good and basic. Circuit if you don't already have it.

Honestly what you have done works very well. I'll only being doing minor things to code and notepad would do . And yours is the only compiler I have that MicroBoot will work with. Everything I've done does not work. I've even installed Ubuntu 12.4 + arm-none-eabi-gcc 4.8.2013.11 with VM. The code can be loaded and run fine but I can't use MicroBoot at all to load code.

Thx for the pdf, didn't had it.
