Good Morning Paul,

I installed the beta Windows 10 64 bit on a clean install of Arduino 1.8.13 (renamed old, and unzipped the arduino zip file...) I installed the beta....

Then first attempt, I tried to reprogram a T4.1 with blink...

And the Blink compiled correctly then tried to download to T4.1, looks like it did, but it is not blinking. And System does not see the Teensy...

I can unplug it and plug it back and it still does not see it... I can do the hold the program button down and get it to go back to default program.

T4 appeared to program fine.

Note: T4.1 with issue has two PSRAM chips on it.

Tried again with fresh just out of the bag T4.1 same issue. Will try again
 
@Paul - did you pull the WIN EXE? My machine cannot get it. First attempt started and halted? ... waited ... Now I can see folder and the exe - but download won't start?

Other WWW stuff works - amybe AT&T is mising something ?
 
Paul quick update,

Tried also on Ubuntu 20.04 64 bit,

Again tried T4.1 with blink (slightly edited 1000->250 as to see difference in blink. Again it programmed a T4.1 (dual PSRAM), After I did the hold program button until it reflashed...

Then Teensy programmed the board and then no blink... Also Ubuntu put up an Error screen:
Sorry, Ubuntu 20.04 has experienced an internal error.
Send problem report to the developers? ...
Click to expand...

Not sure if it would help but it does not look like I can select the text to send...
So here is some dmesg stuff

Above T_4.1 had some QPSI chip(s).

Unpacked a Fresh T_4.1 - it was blinking and connected - Upload fail and button push fail - though TeensyLoader goes through the motions.

To check used TyCommander with same T:\\TEMP\\arduino_build_483495/Blink.ino.hex. It also goes through programming - but device never comes up running.

Did 15sec Restore - TyCommander upload ... no device on reset or power on.

OPEN IDE 1.8.13 with TD_1.53 and upload BlinkWithoutDelay.ino.TEENSY41.hex using TyCommander and it works no problem.
 
Side Note: I ran into issues yesterday or the day before where my builds were not working before this release, but that was because I had my Cores project directory linked into the Teensyduino release (and I renamed cores to different name... It started working again when I removed that link and renamed back...

I also was seeing some screwy stuff when I was building using the Sublimetext with my app that displays information about the build... It is screwy again with the release.

It is simply subtracting what it found for the symbol ebss from the symbol estack...
 
I had github updated my cores but beta 1 released before I swapped so I didn't see anything. And today's testing was IDE only - except TyCommander is integrated on the TD1.53 version - but it worked.

I stared at the .ld changes and didn't see anything obvious between the two 1062's - diff flash size, and add in for the extmem.

@KurtE - does the USBHost lib update include your 512B Serial changes?

<edit> : on td1.53 IDE did restore to teensyLoader for upload, instead of TyCommander

Opened TeensyLoader 1.54b1 which then uploaded to T_4.1 no problem the blink sketch. Just to confirm problem is the HEX not the loader.
 
Well I had my code print out what it had for estack and ebss and it prints:
estack:0 ebss:2002c2c0

But that is also true for T4 now as well... So next up to see why?

Figured out the tool issue:
Code: 
2002c28c B errno
2002c2c0 B _ebss
20070000 T _estack

The code before was looking for B _estack
So just duplicated....
Code: 
			if (strstr(str, "B _estack")) estack = strtoul(str, NULL, 16);
			if (strstr(str, "T _estack")) estack = strtoul(str, NULL, 16);

Just joined the fun here. Loaded a clean copy of Arduino 1.8.13 along with 1.54-beta1 and am seeing the same issues on a Windows 10 64 bit as @KurtE and @degragster while loading Blink.ino. As a second test I went back the 1.8.13/1.53 combo and tried loading blink and got the following error:

Error compiling for board Teensy 4.1.
Oh - have to fix something - downloaded the core the core a couple of days ago let me put it back and retest - this was with only the changes for HAB from what i remember.

Ok put it fully back to 1.53 and Blink works like a charm - so may be HAB changes?

Update>Tried a T4.0 and loading blink worked no issue. The T4.1 issue was the initial beta t4.1 with flash and a psram chip.

I am trying to look at the differences in the code between the two releases and wondering about why the .vectors was removed in both the .ld files as well as bootdata.c

What I am curious about, is in previous build we have a
Code: 
__attribute__ ((section(".vectors"), used))
const uint32_t vector_table[2] = {
#if defined(__IMXRT1062__)
	0x20010000, // 64K DTCM for boot, ResetHandler configures stack after ITCM/DTCM setup
#endif
	(uint32_t)&ResetHandler
};

And we pass that in to:
Code: 
__attribute__ ((section(".vectors"), used))
const uint32_t vector_table[2] = {
#if defined(__IMXRT1062__)
	0x20010000, // 64K DTCM for boot, ResetHandler configures stack after ITCM/DTCM setup
#endif
	(uint32_t)&ResetHandler
};

But the new stuff:
Code: 
__attribute__ ((section(".ivt"), used))
const uint32_t ImageVectorTable[8] = {
	0x402000D1,		// header
	(uint32_t)&ResetHandler,// program entry
	0,			// reserved
We have pointer directly to the ResetHandler, so who sets up the ResetHandler stack?

I do not see any differences in startup.c
 
I'm hoping that USB Type: Serial+Midi+Audio on T4 with Linux can get fixed. Same exact program works fine with Audio only.

Click to expand...

Can you give me a link to the forum thread with that exact same program? And clear / quick way to test (ideally with Linux)?

Looks like I messed with Teensy 4.1 with the last minute HAB changes, so I'm probably going to make some quick fixes and package up beta2 tomorrow. If I can reproduce this problem in only a minute or two, I'll spend a little time trying to get a fix into beta2. But no clear way to quickly test means I definitely won't look at this until after beta2.
 
I did some hacking and my T4.1 programs now... More or less reverted some of it...

Again not sure how much of these changes made the difference. Like the differences in address nor the align statement

Edit: the lines in red are the ones I changed (edit or added)
 
Likewise, NOW is the moment to bring up any issue you believe I might be able to fix quickly, like tonight only.

If I can't reproduce a problem within 5 minutes, I definitely will not work on it right now. But if I can, and if it's not a major rewrite or tough design trade-off to solve it, odds are good I might get a quick fix in tonight.

I did some hacking and my T4.1 programs now... More or less reverted some of it...

my imxrt1062_t41.ld right now looks like:
Code: 
SECTIONS
{
	.text.progmem : {
		KEEP(*(.flashconfig))
		FILL(0xFF)
		. = ORIGIN(FLASH) + 0x1000;
		KEEP(*(.ivt))
		KEEP(*(.bootdata))
[COLOR="#FF0000"]		KEEP(*(.vectors))[/COLOR]
		KEEP(*(.startup))
		*(.flashmem*)


My bootdata.c looks like:
Code: 
//#include "imxrt.h"

#include <stdint.h>

extern void ResetHandler(void);
extern unsigned long _estack;
extern unsigned long _flashimagelen;

[COLOR="#FF0000"]__attribute__ ((section(".vectors"), used))
const uint32_t vector_table[2] = {
#if defined(__IMXRT1062__)
	0x20010000, // 64K DTCM for boot, ResetHandler configures stack after ITCM/DTCM setup
#endif
	(uint32_t)&ResetHandler
};
[/COLOR]

Have running BLINK and no delay - can edit and upload to work.

I made just the edits shown above ( bootdata.c color coding was on existing code - it was the block above that was needed )
 
Ugh, this makes no sense to me....

But adding a single nop instruction at the beginning of ResetHandler (without the vector_table array in bootdata.c) also fixes the problem with Teensy 4.1.
 
Even stranger, adding a single nop instruction *later* in ResetHandler also makes Teensy 4.1 work!

Very mysterious......
 
Nice to be in good company ... err - well not really ...

Can confirm both blinks work with this in startup.c:
Code: 
void ResetHandler(void)
{
	unsigned int i;

#if defined(__IMXRT1062__)
	[COLOR="#FF0000"][B]asm volatile("nop": : :"memory"); // why oh why?[/B][/COLOR]
	IOMUXC_GPR_GPR17 = (uint32_t)&_flexram_bank_config;

Also confirm the only changes made before are as in p#18 - and they were undone to see the nop work.
 
@Paul - for this post using T_1.54b1 : Schematic-error-in-T4-0-or-T4-1-on-SD-pins

I put a 16GB SD card on a T_4.0 breakout ( the FRDM4236 ) and it worked to sdFat-Beta build and run Formatter and SdInfo.

Then with above 'nop' edit place both sketches ran and built for T_4.1 as well.

And for added fun - I restored startup.c to no added "nop"

And put back the p#18 edited files, both sketches ran and built for T_4.1 as well.

// why oh why?
// why oh why?
// why oh why?

Indeed ...

Then to complete the TriFecta of confusion: Restored the td1.54b1 sources
sdFormatter - builds and fails to show on reset after upload, and on program push programs again and won't come up
sdInfo - builds and fails to show on reset after upload, and on program push programs again and comes up running, but won't come up when unplugged/replugged to USB.
 
Morning all
Going to add to the confusion this morning. I retested BLINK on a T4.1 with compile options from smallest to fastest with the even stranger result that at all compile options BLINK WORKED!!!!!! Compiled and loaded. Also ran the sm_alloc simple sketch and worked as well. Note: This is with absolutely no changes to bootdata.c!

I also was seeing some screwy stuff when I was building using the Sublimetext with my app that displays information about the build... It is screwy again with the release.

I'm pretty sure these problems are due to not-so-robust parsing of symbol table data, and lack of error detection. I'd recommend adding a boolean for each item which defaults to false. Set each boolean to true as your parser finds each number. Or maybe use a bitmask and set a particular bit as you find each item. Or if you don't want to add extra variables, at least initialize all of these with a highly unlikely non-zero number.

Code: 
        unsigned teensy_model_identifier = 0;
        unsigned stext = 0;
        unsigned etext = 0;
        unsigned sdata = 0;
        unsigned ebss = 0;
        unsigned flashimagelen = 0;
        unsigned heap_start = 0;
        unsigned flexram_bank_config = 0;
        unsigned estack = 0;

Then after you're done parsing, check the booleans / bits / numbers to detect if your parser didn't find any of the required info. Probably best to print an error message about which info wasn't found and quit. If you go on to call printnumbers() when some info is missing, you'll get wrong results.

Yep - it was a quick and dirty (originally from Frank :D ), that I have played with and find useful. I probably should cleaned up some. Especially how it depends on exact strings...
Also maybe look to extend it's output some to maybe print out additional information (if we have it) of if the code has variables defined up in PSRAM...

Besides may have to add section for MICROMOD ;)

EDIT: - I mentioned this app more because I noticed the change a couple of days ago and builds had stopped working with the github CORES linked into my builds and so I removed the link and went back to released version of cores and things worked again. I just assumed I must have screwed up something locally. Probably should have mentioned it then and debugged.
