Re: Any ideas what creates a .sgl firmware file ?

Guys, Thanks for your help,but I think trying to decode the firmware update file is impossible / impractical, and there are probably better ways to get at the firmware. I found a post on Hackaday, where someone had managed to extract the firmware from another radio by the same company, by exploiting...

Re: First experience review of allpcb, $15 for 5 100x100mm boards, $5 for 50x50mm boards, shipped DHL

Hi Victor, I'm a bit out of the loop at the moment as I've had other more important things that I need to do (repair my house!) Perhaps if some other people register with AllPCB via your link, then you'd get some more credit ?? I dont seem to be getting spammed by AllPCB, so I don't think its very h...

Re: Any ideas what creates a .sgl firmware file ?

Andy Yes. The radio is a Radioddity GD-77. Well I've already figured out that its actually a Tytera MD-760 but that Tytera (as there are tell-tail signs of the product code in the data files, and Tytera are selling this radio under the Radioddity brand name with the GD-77 model number. It would be n...

Any ideas what creates a .sgl firmware file ?

Hi have a firmware file for a digital radio, which has the .sgl extension, and I'm trying to work out what created it. The file is being uploaded using STM's DFU DLL's, so I initially thought the processor in the radio was a STM32 However someone sent me some photos of the inside of the radio and it...

Re: nrf24 / esp8266 /xbee section ?

LOL... Believe it or not, my 2 year old hot water service ( boiler) contains no electronics at all. It just gas a gas pipe to it, and uses a pilot light lit during installation via a mechanical piezo system ( hand operated push button). And has a mechanical thermostat, which I think is a bi-metal st...

Re: 2018Jan02 Core Version

Ray, It’s best to use git to determine why a change was made. I find GitHub has the best UI for this. Each commit will have a comment, and it’s normally possible to track down if the commit was in response to a merge of a pull request, in which case you can see who the PR was from. In some cases, th...

Re: In car multigauge

Wire changed from software ( bit banged) to Hardware, and this generally works,
however there may be a problem with multiple different I2C device libraries, which is probably something to do with the bus not being released.
Unfortunately I have not had time to test this potential problem

Re: Board loses program after boot

Its no solved. I gave up using the board which had the problem, I suspected it was faulty. You could try posting to STM's own community forum as this is a general question about their processors not the Arduino core (Or you could try compiling using something completely different e.g. Atollic TrueSt...

Re: Greetings from Max in NY

Windows 10 is know to work OK. A common missunderstanding is the bootloader just provides DFU (not Serial). Maple mini boots into the bootloader, Bootloader appears as a DFU device on USB After timeout (waiting for upload) bootloader jumps to sketch Sketch provides Serial USB If your board does not ...

Re: Boot from sketch on SD card

Most or the STM32 cores are setup to work with a bootloader which is 8K (though the Maple mini settings for old bootloader will be 12k)

So you can have a bootloader of any size you like, just as long as you modify the core you are using to suit that size of bootloader
