Can someone point me to a good description of how to re-flash the Devo 7e bootloader?


Thanks!

What did you do that itis necessary?

I don't have a great description, but if you have a SWD debugger/programmer (STLink/V2) , you can install the bootloader by adding jumpers to the boot0 and power-override pads (the only 2-pin 0.1" pads on the board), and then using the STLink sftware to install the bin at 0x08000000

Thanks. Don't know what happened. Was attempting to load Deviation via Linux. Got lots of error messages. Then the thing died. No lights, no nothing. Perhaps it's something worse than a trashed bootloader. Will see.

Try pulling the battery for 15 seconds. That"s generally enough.

Do not ask me questions via PM. Ask in the forums, where I'll answer if I can.

Do as above but also load again at 0x08003000 And this bit is important don't erase memory for second flash!
It does work, honestly.

Is there a more detailed writeup of the process, items and files necessary?

I'm good with a soldering iron, etc. Not much knowledge of the processor in the Devo. Done Arduino and others.


Thanks

It turns out I had to do this today, so I can be pretty specific.
1st you need an stlink-v2 and a copy of the devo7e bootloader

You'll be using the 20pin header on the stlink.
on the 7e board, there is a 5-pin unpopulated header below the MCU, one pin is labeled RESET. We;ll call this pin '1'
connect pin1 (reset) on the Tx to pin 15 (NRST) on the stlink
connect pin2 (tms) on the Tx to pin 7 (TMS) on the stlink
connect pin3 (tck) on the Tx to pin 9 (TCK) on the stlink
connect pin4 (GND) on the Tx to pin 20 (GND) on the stlink
connect pin5 (Vdd) on the Tx to pin 1 (Vcc) on the stlink

just above the 5-pin header is a 2-pin unpopulated header. this is BOOT0. you need to place a jumper between the 2 pins.
On the upper left of the 7e circuit board is another 2-pin unpopulated header. This is power bypass. You'll need to short these together too, but not yet.

You need to install the software for the stlink-v2 to your PC (Windows only)

Now, plug in the st-link to the PC. It should be detected and drivers installed
Startthe ST-Link software.

make sure there are batteries in the Devo7e, and apply the jumper across the power bypass.

Now press the connect button in the stlink software on the PC. It should connect. If you get an error message, you have a connection wrong somewhere.

You will need to do a bulk-erase of the chip 1st. then you can load the bootloader and do a program&verify.
your bootloader is now loaded.

You need to disconnect the jumper on BOOT0 and power bypass before you do anything else.

Well I thought I had the programmer needed, till you said "20 pin header", I have one of the $5 Chinese "ST-Link V2 mini emulators" that I bought and use for bradwii, will that do the job?

Will the USBasp - USB programmer for Atmel AVR controllers from Thomas Fischl work for this too?
That's the one I used for some Arduino projects with ATMEL MCUs.

Kind regards,
Tom

No, that's an AVR programmer, totally different from STM. You'll need the ST linker clone posted above.

Okay, like I thought.
Then that's the one I'll order: ST-LINK V2 Emulator Downloader Programmer Support STM8 STM32

Thank you for the quick reply Cereal_Killer!
(By the way, are there anywhere some more detailed informations about your nice Devo 7e LED mod?)

Unfortunately no, but the only thing I did differently than everyone else's LED modding was to add a red LED in parallel with the piezo buzzer so there was a red flash anytime it beeps. Really nothing difficult at all. If you can do the range mod LED'S are child's play.

Hi
I am trying to change bootloader for devo F12E 1.6B to devo F12E 1.6A which is 100mW.
Does anyobdy did that already and can give me some instructions how to do it?

Can i extract it from another 7e via ST- Link ?.

Here you go.

The stock transmitter is read protected so stlink can't download it for you.

Ahh i see. That's maybe why when i was messing about a few weeks ago with the ST serial bootloader, it just gave me the "protected" message and i gave up.
Thanks for the quick reply.
One more question ...
Is the devo7ebootloader_256.bin file for a different chip ?.

Thanks.

That's right. I believe PB wrote a separate piece of code to loaded onto the chip to read and dump the boot loader. I've seen references to it in the source code, but have not played around with it.

devo7ebootloader_256.bin is a modified version that PB put up if you upgrade your stock chip to the STM32F103RCT6 which has 256K instead of the stock 128K so that we can upload a DFU file bigger than 128K. In my case I upgraded to the STM32F103RET6 (with 512K). The 256K boot loader works for both though.
