Flashing back the original FW

Open struncp opened this issue 6 years ago • 9 comments

Hi, could you give some instructions on how to flash back the original firmware from the .bin file, please? Prefferably on windows, I can't find a way how to do it anywhere.

Also this is probably just a fault of my piece but I can't get working any dual FW, just notfastenuf's acro only (hence the request for stock). Have you ran into something like this before?

Thanks for your time

to flash it back use the stm32 st-link utility from the st site or here https://app.box.com/s/flf2d36eoigv7keel253p5yssy2a8nac

open the utility, select menu "target", then program or program and verify, with the quad connected and powered up

what happens with the current attempt. does it bind, or flash lights?

It binds, flash lights, it even reacts to throttle. The problem is that on level it constantly goes slightly front and left (trims don't react) and on acro it banks in the same directions just by itself. Calibrating accelerometers doesn't help at all.

I reckon it's not the HW problem because previously mentionet FW from notfastenuf is working properly but then again I smashed this quad all over the place so many times that I'm not sure about anything anymore.

Also my FC is not entirely level (see photo) in the frame but that's what accelerometer calibration is for, right?

Going to try the stock FW now

EDIT: Stock works. Thanks for the instructions!

the trim buttons don't work in this firmware. The accel calibration works ok on this type of quads, but it only works in level mode

if you are using the stock tx it might be that, it has bad centering, you might be able to improve it but acro on stock tx is not really there

Stock kidney tx is the problem then. Shame the only dual FW can't overcome this as some of the others. Will some other toy txs work or is this a taranis-with-multiprotocol league?

where to get original firmwarw (.bin)?

2black0 avatar Aug 20 '18 09:08 2black0

just get from the bin folder, but after flash it, my board only flash the 2 led (blue and red), cant bind

2black0 avatar Aug 20 '18 10:08 2black0

maybe something is damaged, the antenna or the radio crystal for example
