I deleted devo 7e Bootloader. But now working...

Hi
Well I've been very silly(not the word i want to use) While i was poking around Devo7e using StLink v2. I thought i was just looking But! was making changes, Flash is now unprotected...whoops

Now Walkera's DFU loader does have CRC checking but ST Loader does good job too. Well not going to find Walkera's loader anywhere and ST's i just can not find it anywhere, maybe just not using right wording in my search.

I've looked though forum and i can find info about bootloader but nothing on how to go about replacing it or even files needed.

Any help would be great Thanks

Thanks. I'll do that and hope

Pm sent.

Now I have STlink can i manually flash and run code, if so how ?

Well St bootloader is intact and quit easy to get running but no luck as yet re-flashing Devo7e.bin.
Anyone got other info ?

ahh! that would be why then

So compiling without offset not going to be very easy...doh

i just renamed dfu.py so it couldn't be used.
Bin file still looks the same ...bugger

used address 0x08000000 and 0x08003000 and no joy.
Far to many options and I'm only guessing

So many pieces to the puzzle....

Well I got lucky and change 'option bytes' and it running again!! No walkera loader so have to open tx to do updates but does free up 12k, so not all bad.

Might be useful to the forum if you explain how you did it and where to make the connections.

I can do that. I used STLinkv2 but using usb/serial should do it as well.
I'll do some screen grabs. Mostly because I don't understand the options I used and someone with greater understanding could complete the picture with little more info.

+1 !

Yes I shall do write up on updating TX without Walkera loader, using STlinkv2 and ST serial bootloader. Results are little odd but all appears to work OK.

Well i have a Q: about how to compile Deviation Nightly Builds ?

I made minor change to make file so i could compile using 'make target=devo7e' which works fine, no problems there.
Still to re-flash using ST's serial bootloader i need Bin file that i 128k in size and loads @ 0x08000000. Though code needed to run start's @ 0x08003000.
Using STlink I can use Bin file that make spits out but using ST serial bootloader I have to use a full 128k bin otherwise it don't work.
Can make file be simply changes to do this?
