Major bug on G2 - Oulan - 03-06-2019 12:47 PM

When making some test to optimize some code I got a very nasty bug

Program leads to "reboot screen"
"Your HP Prime had a
problem and will
will reboot in 3 seconds" ...

got the trouble even after CFO,reset finally the problem disappear ... then reappears

AFTER CFO-ON, format C:, reset
mem INFO gives Memory 246.86MB, Storage 461.68MB
next one, reset
mem INFO gives Memory 246.93MB, Storage 461.59MB
next one with format C:, reset
mem INFO gives Memory 246.88MB, Storage 461.68MB

So it seems that I definitely lost 256MB of ram Sad
--EDIT--
Or I was misreading the info at first, I think that I saw Memory about 400MB but
as it seems that the G2 only got a 256MB ram chip so I was certainly misreading ...
So ram seems ok
--EDIT--

All tests seems ok

First run after CFO format reset was ok, then the pb re-appear (running prog with calc connected on USB)

Nexts runs leads to reboot too even with calc disconnected from USB

Program follows as source (sorry for the size)

=============================================
Binary at bug at end of page, test42-bug.zip, reboot picture there too

On a windows 10 Virtual Prime Build 2.1.14181, no problem at all

Re-flashing the firmware does not change anything.

RE: Major bug on G2 - Martin - 05-13-2019 08:45 PM

It looks like the BREAK; command in a program, is the cause of this issue.
Go to HELP, and search for BREAK.
The example gives you a program Demo_BREAK.
When running this program, the Prime reboots.

I have had to patch several programs, not to use BREAK; and instead of that,
construct some other condition to leave a loop.

Is there a chance to get that fixed in the next firmware release?

Thanks in advance.

I tried this (Demo_BREAK) again with a clean (Format C) Prime G2.
=> Same behavior => Calculator resets.

Can anybody confirm this issue, or does my Prime G2 hava a hardware issue?

Thanks in advance

Confirmed, paperclip reset required after.

RE: Major bug on G2 - Dirk.nl - 05-18-2019 01:02 PM

Confirmed!
Paperclip reset was not necessary.
Reboots after some time.

My G2 does the same thing. It takes a while but it resets itself with no paperclip needed.

RE: Major bug on G2 - DA74254 - 05-18-2019 07:35 PM

Confirmed.
Resets itself, but no paperclip needed.

Any way to find out if this problem with BREAK is on HP's radar?

I was an early adopter of HP Prime and it was a bumpy experience at first, but eventually smoothed out. I bought a HP Prime G2 last week, updated it using connectivity kit, and it looks like I have to relive a similar experience again! Sure enough, the BREAK command crashes the calculator. Makes me wonder what else might not work quite right.

I was going to give my old HP Prime to a student, but now I'm apprehensive and so will wait to see how HP deals with this.

RE: Major bug on G2 - srbrenton - 10-18-2019 11:06 PM

I bought my G2 about a week ago (October 7).
In my case, I don't have a BREAK in my code but WAIT/ON seems implicated.
Normally (G1) this code draws a picture and waits for a key press and returns the same.

Typically I'll press the ON key and get '46' in an alert box.
However, as I duplicated this sequence I periodically the get three second reset warning (no keycode) and then the Prime resets.
I hope this helps someone who knows what is happening.

Code:

EXPORT ORBITDGM()
BEGIN
RECT();
FOR C FROM −2 TO 0.25 STEP 0.00625 DO
X:=0;
M:=142*(C+2);
FOR I FROM 2 TO 100 DO
X:=X*X+C;
IF I < 30 THEN
CONTINUE;
END;
N:=60*(2-X);
PIXON_P(M,N,#FF00FF);
END;
END;
WAIT;
END;

Thanks,
