Win 10 :: installed TD 1.52 B5 - that went well. I deleted ALL of Teensy\AVR first to overwrite that in exisiting IDE 1.8.12.
 
Win10, Teensy 4.0, Teensy Convolution SDR, works well!

Win10, Teensy 4.1, 2 PSRAM chips, tried several example sketches, including PSRAM memory display ("16MB"), works well so far, however the T4.1 does only program after pressing the program button
 
@DD4WH: with T_4.1 fresh from the mail and IDE 1.8.12 w/TD1.52 B5 it does an AUTO Upload from IDE.

Wondering if you have an alternate USB cable? Is TyComm or other 'external' SerMon in use holding the USB port open preventing Auto Upload?

I did the PSRAM init test with no chips yet soldered and it works to not find them and see them not work. And from the IDE that works with Ctrl+U to t_SerMon and IDE_SerMon.

<edit>: TimeRTC.pde :: Working from Windows to pass the current PC time to T_4.1 on upload.
> Note::
>> t_SerMon restarts properly after upload
>> IDE_SerMon does not restart after IDE upload with this sketch? It stays "Offline"

<edit> Fresh T_4.1 - did 15s Restore with no problem and returned to work for AUTO upload of the TimeRTC.pde sketch as above
 
I'm having the same issue since ages - any teensy.
Incomprehensible.
Sometimes it works for days without me having to press the button - then - with the same sketch - it doesn't work anymore.

Sometimes Arduino forgets the serial port - and I have to select exactly the same one again.

This happens with all cables.
I suspect windows is the problem. Or, more likely, a bug in the (patched?) Arduino or associated tools.

Then, the PJRC-patched Ardunio has still the problem, that with very fast prints - the Serial monitor prints random pc-memory contents (a pointer going wild). Race condition.. After while it hangs completely (no suprise, then.. (pointer))

I am wondering, I was trying T4.1 (without memory) in my Lynxmotion Servo board for first time and it would not program using my updated TyCommander... Tried a few different things.
I undid the TyCommander and I reinstalled the new beta to make sure.

I then did the N second reset of the board to make sure back to default and now I can program it... At least with one simple case.

Now try the next one.

It could be a bug. Maybe open a command prompt window and run the "teensy_ports.exe". It should be in C:\Program Files (x86)\Arduino\hardware\tools. If you just leave it running, you'll see it prints JSON about each USB connect and disconnect event, or updates as Windows makes more info available.

I can't do much about those Windows problems.
 
:eek: Do you believe in the Users?

Thank you Frank B.

Catching the NULL cures the symptom, but there has to be a reason why this error evolves.

Anyway, I've tried several imports that failed before and work now, so I think it is important to merge this to 1.52, so the audio tool can be used for more complex projects.

I remember you've made some important adjustments forTeensy 4.x to the tool. Do you plan to commit them, too? Or what about a second index.html for Teensy 4.x?
 
I think this is wrong in teensy4/startup.c
Code: 
CCM_CBCMR = (CCM_CBCMR & (CCM_CBCMR_FLEXSPI2_PODF_MASK | CCM_CBCMR_FLEXSPI2_CLK_SEL_MASK))
		| CCM_CBCMR_FLEXSPI2_PODF(7) | CCM_CBCMR_FLEXSPI2_CLK_SEL(0); // 49.5 MHz
needs "~"
Code: 
CCM_CBCMR = (CCM_CBCMR & [B][COLOR="#FF0000"]~[/COLOR][/B](CCM_CBCMR_FLEXSPI2_PODF_MASK | CCM_CBCMR_FLEXSPI2_CLK_SEL_MASK))
		| CCM_CBCMR_FLEXSPI2_PODF(7) | CCM_CBCMR_FLEXSPI2_CLK_SEL(0); // 49.5 MHz

i was having a heck of time figuring out why PSRAM clock was running at 90mhz when code said 49.5 !


EDIT:
hmm, looks like that was fixed on github 18 hours ago with
Code: 
CCM_CBCMR = (CCM_CBCMR & ~(CCM_CBCMR_FLEXSPI2_PODF_MASK | CCM_CBCMR_FLEXSPI2_CLK_SEL_MASK))
		| CCM_CBCMR_FLEXSPI2_PODF(5) | CCM_CBCMR_FLEXSPI2_CLK_SEL(3); // 88 MHz
