Devo f7 for DelFly

I'm not really much help to you with code but can say when you don't have serial flash connected code will still show flash drive in windows, asking to format it.

Hi, I have devo F7, and I'm so anxious, I hope that the devention can work on my devo. If you need some help, maybe I can help you with this work, maybe I can help you with the OSD.

Tnx! Yes it shows the usb drive and asks to format it. But it can't format the drive, so I'm not able to upload the config files to the transmitter. Without the config files allmost nothing of the transmitter works.

Not sure how far you want to go with flash but 2 meg are very cheap. Still 512k your going to have to be creative 'Microchip' do sample 32meg. I can mount one to make sure they work if your interested ?

That's a good idea If you could test it that would be nice!
I already removed a resistor inside the 5.8GHz receiver to receive the correct band, so changing the flash wouldn't be a problem if it works.

Had a thought if you post a complied HEX with pins used i can try code my end ?

How I can help you with this port to the deviation to F7?

Sorry for the late response, but my devo F7 was broken and needed to replace the STM. It is now working again, and also replaced the flash memory(4MB now).

I don't have the devo F7 bootloader yet, so I'm not capable of flashing the device with DFU. I'm now flashing with SWD, so in my repository this is changed. So make sure you change it back to DFU before flashing(else you will also lose your bootloader).
Btw. if anyone could get the original bootloader out of the device that would be nice

To try and see my work in progress:
github.com/tudelft/deviation

This is what currently is working:
- Capable of setting up the USB
- All normal system functions seem to work, like battery warning etc.
- Made some basic LCD functionality to write text at a certain position.
- Made the flash screen, the USB screen and also a part of the main screen.
- Also made a part of the menu by showing the menu title.

What needs to be done:
- Getting the rest of the menu to work
- Finish the rest of the character map
- Maybe replacing some of the characters would be nice (don't need chinese characters)
- Finding out how to make some special text (like big font etc.)
- Maybe get rid of some of the unneeded GUI structure, but I'm not that into deviation so I'm not sure how to implement this the best way.

This loader www.deviationtx.com/forum/7-development/...fully?start=20#16254 does work for devo 7e and is windows based, sorry.

try the pre-compiled bins and if it works as is you maybe lucky...

Nice job

I'm working on linux, so for now I will be using SWD. It is also much faster, so easier for debugging.
But yeah if I want the original firmware back, I really need the original bootloader or a similar one with the same encoding. So that's why I want the original bootloader. I can maybe lent another devo F7 and extract it from that one, but if someone else has it already or could extract it for me that would be nice!

I didn't replace the MCU with a better one, but can maybe do that later if it is really needed.
I think the biggest problem was the flash, so I fixed that part.

I was suggesting if you load bootloader and it shows its self on your system you could maybe use the devo7e loader ?? Just a thought.

I think the devo7e bootloader won't work, because it always show something on the screen. Since they have a different screen, with different drivers that won't work

But yeah maybe it works without screen, that's possible.

I now got the basic menu to work! It is looking pretty good, you can browse through it etc. I already fixed the Channel Test page, so that one is also correct now. But I don't know if I'm missing something, because I don't know the original menu structure etc. So if someone can place a video or something like that online on how the normal menu of Deviation on a black/white screen works.

Now need to look into some more of the other GUI parts, then just plain text. Already showing the selected menu item with blinking text(works pretty good). But now I wanna make the transmitter config menu, because then I can easily configure some parts.

Yes I already placed the source code online
