Quote from: DarrellW on Sunday,September 21, 2014, 15:08:24 Read the post with great interest, does this now mean that if you have got an Afro flash linker that you can now flash any atmega based esc using this method?
Quote from: Hands0n on Sunday,September 21, 2014, 15:25:24 Yes, only if your ESC software has a bootloader, which you can load using the usual method. Once done you can use the flash linker going forward.
Quote from: DarrellW on Sunday,September 21, 2014, 15:37:09 Sounds good, but how do I know if the esc has a bootloader?
QuoteYou will need to select the right options in the lazyzero KKMulticopter Flashtool program to successfully flash your Electronic Speed Controllers;
Quote from: teslahed on Sunday,September 21, 2014, 17:13:11 If flashing ESCs with SimonK for the first time using a socket tool then you need to enable the bootloader option as described in post 1;Once you';ve done this then you can use the USB flash tool via the servo signal wires from then on.If you';ve bought SimonK flashed ESCs from any reputable source then the bootloader should be enabled by default. Afro ESCs from hobbyking come with the bootloader enabled out the packet.
Quote from: nub on Sunday,September 21, 2014, 22:04:34 not sure if this a daft question or not but can i rip/download simonk firmware from an ESC to put to another?
Quote@teslahed said:You will need to download the latest version of the SimonK firmware. This is the improved firmware that you will be uploading to your electronic speed controller to improve it';s responsiveness and remove ';features'; that work well for planes and conventional aircraft but are not so good with multirotors, like the low voltage cut off which will save your lithium polymer battery but destroy your quadcopter. Not all electronic speed controllers use the ATMEL chip but many do. This document has a list of the different common Electronic Speed controllers that people like to flash;https://docs.google.com/spreadsheet/ccc?key=0AhR02IDNb7_MdEhfVjk3MkRHVzhKdjU1YzdBQkZZRlE#gid=0As well as including links to the firmware itself. It';s worth looking closely at the document because there are different individual files for different Electronic Speed Controllers and if you pick the wrong one you could damage your speed controller. Looking at the document I can see that I need to flash the ';bs_nfet.hex'; file which will be included in the download found here;https://github.com/sim-/tgy/downloadsNew versions are released periodically - it';s probably best to get the latest (at the top) unless you know of any problems with this version, then try the next one down.Source: http://www.multi-rotor.co.uk/index.php?topic=1079.0
