      Yes, what I'm after is a simple standalone GUI program that can upload ehex files to T4.1 without pressing the button on the board, and can run on Windows or MacOS. I sent a message to Koromix last year asking whether there were plans to...

      p.s. note that I'm referring here to stand-alone Teensy Loader use, without Arduino running. When called from within Arduino (after compiling), Teensy Loader starts the uplaod automatically, and with the extended 45 sec time-out I get no errors...

      Yes, after I load an ehex file into Teensy loader, it doesn't automatically start the upload to the Teensy. It shows the notice to press the physical button on the Teensy, and disables both Program and Reboot options (regardless of whether Auto...

      Excellent, thanks very much Paul! 45 seconds seems to do the trick for me. No errors so far with any of the T4.1 boards I've been testing, and the program auto-boots after upload every time. Do you happen to also have a MAC/OS version that I...

      Sure, understood. I'll see what I can do, but so far the modifications I've made to allow me to share the hex have also alleviated the problem.

      I opened two new Teensy 4.1 boards and tested those today, as well as retesting two of the boards that I've been developing with, which both showed the problem I've mentioned in this thread. For the new boards, I cut the VCC/USB trace and...

      Thanks Defragster. Maybe I misunderstand your example, but the problem I'm seeing relates to how much FLASH is taken up (mostly) by my large constant data arrays stored there, rather than the RAM2 use for the delay line. And it also needs to be...

      Thanks for the response Paul. Unfortunately I can't share the problem hex file as it stands, as it's commercially sensitive. But maybe I can modify it so it isn't functional but still produces the loader problem. If so, should I send you a...

      Also, I'm not sure who authored the GUI version of the loader (presumably Paul?), but it would be ideal if the timeout value for that could be changed.

      Thanks very much - definitely sounds like it's worth a try. Is the Windows version available for download? Another plus might be that it could be an alternative for my end users having to use both Teensy Loader and TyCommander - the latter to...

      I have a large synth project (much too large to post code) that stores many constant arrays containing raw drum samples in FLASH: FLASH: code:361728, data:7052072, headers:9172 free for files:703492 RAM1: variables:94496, code:358152...

      With the virtual ground approach there's likely a considerable risk of damaging the HP output if there's any other ground connection between the synth chip and the audio equipment you are connecting to the HP out. If you must use HP out, a...

      Thanks very much for this. I ran into the same problem about a week ago on a T4.1 where I assumed I could get a stereo delay time of 2 seconds, but could only make it work up to about 1.2 sec until I changed the AudioStream.cpp define value for...

      I didn't think you would need to do that if you use the code I posted in #27. I don't have time at the moment to double check that but perhaps you could? I recall the (sparse) data sheet does claim the two DAC outputs are synchronously updated...
