I can sucessfully flash a small “blink” firmware to my :spark:. But when I deploy my fancy firmware it keeps restarting. Sequence: green flashes, cyan flashes, then 4-6 red flashes, and it starts over with green flashes. I posted my app here so you can try it as well. https://gist.github.com/syno…

Coffee, it sounds exactly like an out-of-RAM problem, not program or flash space issue. Are you compiling on the web IDE or locally?

I am compiling online. i was expecting that the web ide would tell me if it was too big.

There is another thread currently going on about ensuring sufficient RAM: [image] uint8_t my_data[256000]; Compiles? Trying to track down a bug when i wanted to see how much ram i had left. I created a variable uint8_t my_data[256]; I then started kicking it up to see when the compil…

@peekay123 @BDub @zach I’m having a issue trying to load code to my Spark Core via the Web IDE. I have code with lots of LCD screen Bitmap image data. The Web IDE compiles the code just fine but when I try to flash the code to my Spark Core it simply will not start sending the data to the Spark so…

Yes if it’s too large it will hang, but I don’t know what part of the mechanism makes it hang. Programming locally is so much faster though so if you are developing something and needing to debug it, local is the way to go.

@BDub I erased some of the code and it then compiles fine so it must have been over sized. The Web IDE says its uploading but it never triggers the Spark Core to Flash Purple normally, it just sits there and does nothing. About programming locally, is the new Local IDE that the Spark Team came out …

I’m not sure about the CLI because since I had issues when I first used it, I kind of stopped using it. I haven’t seen any updates about it, so I’m not sure if it has received any yet. It has a lot of potential though so I would like to get back to it for things. I “think” it basically sends your…

@BDub So I should just stick with mastering the process that I followed that worked for me in the past it sounds like. I had some issues with it for some reason that cost me 6 hours of frustration so I deleted everything and just waited for updates to hit the Web IDE. Looks like I’ll need to try to …

RWB, the web IDE should warn the use when the RAM used goes over the known limit. Any thoughts BDud?

@peekay123 @BDub I was basically saving about 13- 128x64 Bit Map Images that the Digole converter spit out and saved them in the main loop. There was no warning via the Web IDE about ram or memory size issues. I just said Successfully compiled! Good Job! Then it would do nothing to the Spark Core w…
