T3.5 now has 256K of memory - Error on uploads #26
Comments
Thanks for the report, It should be fixed in the latest development build (TyTools-0.8.8-24-g569e504). Feel free to reopen the bug if it does not work for some reason. |
Well actually, since I don't have a Teensy 3.5, can you confirm if it works? |
Thanks!
It appears to work on my T3.5 I was testing with!

If it does I'll make a new official release.
Thanks!

I just downloaded and integrated the above new TyComm and sent a simple sketch to my T_3.5 with no trouble. Would have tested sooner - but 'somebody' :) told me it wouldn't matter :) Niels - Good Work on TyCommander! PJRC is advancing the multi use Teensy case with new Teensy_Sermon [ multiple IDE's can now open and program multiple Teensys ] - but your work focused on the Loader/SerMon combo is still much better! It doesn't get confused with multiple instances of SerMon touching the active devices - and the GUI support with RESET and Bootloader buttons is awesome. Also the implied SCROLL stop as you have it is awesome - versus the 'checkbox' autoscroll copied from Arduino SerMon. |
Niles - TyComm USB SerMon is a bit faster than the new PJRC scheme in general. I've got a T_3.6 on USB3 port pushing ~28,000 messages into TyComm and using the Teensy_sermon it only pulls fast enough to get ~27,000 - not a huge difference - but no slower. TyComm UI does get a bit 'clunky' with 200K line buffer with 28K messages/sec - but dropping Options to 20K line buffer fixes that. On a USB2 or USB3 hub the transfer rates drop to 20K BTW - and on USB3 port a T_LC is only 17% slower at this pure print task sending ~24000 messages/sec and the new Teensy_sermon can keep up with that. Not to mention - though here it is - the Loader interface is better too. Also - other subtle things that make usage very handy:

Great! Thanks for testing it.
Yeah, I may have messed up :) For some reason I completely forgot about the firmware identification code, for which I rely on the (initial stack pointer value, size of the interrupt vector) couple... and the initial stack pointer value depends on the RAM size, obviously. Anyway, glad to see this little software is still useful :] |
This 'little software' is one of the biggest performance boosters I came across the last years. I do a lot of development involving more than one teensy and can't remember how I ever could work without tytools :-) Thanks for that very useful piece of software. |
I don't see how to RE-OPEN …. The Beta 4 fix shifts RAM wrongly and causes runtime errors. RAM alignment is off by 4 bytes from 262140 goes to 262136. FrankB made a fix that results in: The changes he uploaded are to Boards.txt :: and to \hardware\teensy\avr\cores\teensy3\mk64fx512.ld :: |
New build will be up soon. I'll wait for Teensyduino 1.42 final to make a new release :) |
I want to add a new per-board option for this release, "Ignore firmware version check", to work around this issue in case (when?) this happens again. |
Uploaded two sketches ( on IDE with above changes ) - and No Error and a running sketch! |
With the new beta (https://forum.pjrc.com/threads/52090-Teensyduino-1-42-Beta-4),
The Teensy 3.5 now has 256k of memory instead of 192 ;D
But now TyCommander shows an error if you try to upload a new program to the T3.5
