See this message above (viewtopic.php?p=9071#p9049)

However, there are multiple benchmarks available so we need to get clarification from Mark regarding which benchmark it is that he used.
I just wish I could try any benchmark on a 3.10/3.10 calc... :roll:

I've not had a crash yet. Jumped several versions to this one. Haven't done anything too intensive yet but all seems well so far. Happy to run a stability-checking benchmark if requested

Still running DMCP v3.8 / DM42 v3.7.1. I'll wait till the dust has set... ;)

Hi all,
Approximately how long does the flash take?
When you eject the partition and hit ENTER when prompted to flash the firmware, do you get a message saying its flashing or does the screen stick with the press enter to flash etc. screen while it's flashing?
Presumably when complete, you get a confirmation message?
Thanks
:D

@Leechpool:
Flash should take under a minute.
You get a status display with info about the installed firmware and an "Press exit to continue", where the DM resets and loads whatever you have asked it to load.

For the others; I've tried all the programs I have loaded without crashes and also a solver equation I have. Have not yet tried any integration, but so far my DM42 runs 3.10 without any hiccups or battery drain.

Until we hear otherwise, I guess Mark is referring to the Summation based benchmark for calculators. If that's the case, I don't know the exact code Mark ran, but here is something I knocked up:

Code: Select all

00 { 26-Byte Prgm }
01▸LBL "BENCH"
02 STO 00
03 0
04▸LBL 00
05 RCL 00
06 ATAN
07 SIN
08 E↑X
09 3
10 1/X
11 Y↑X
12 +
13 DSE 00
14 GTO 00
15 END
Put number of iterations in X, then XEQ "BENCH".

How high do you go on the "bench"?
I tried 10.000 and it took abt 29 seconds. Version 3.10 (IFC 03.09) with DM42 3.10

Update:
The 29 second run was connected via USB and thus "unlimited" power.
Running 10.000 off of battert (2,96 volts) it crashed after abt 5 seconds.

Another update:
100 runs successfully and finishes at abt 2 secs. 1.000 crashes after abt 3 secs.

Am I to understand that people other than Mark are finding V3.10 to be unstable? I'm not talking about the excessive power consumption when off, I mean the device crashing.
Yes, I was able to reproduce another error on two different devices (SN00480 and SN00155).
For example.
Input:
5
ENTER
1E10
y^x

Now the machines freezes!
Then I run DM42 3.9.1 on DMCP 3.10 like Mark Hardman did and all worked fine ("Out Of Range" or 1.E6145).

On machine with SN00480:

Bench with DM42 3.10 on DMCP3.10:
I tried 1E4 on USB, ok.
I tried 1E4 on Battery, the machine freezes.

Bench with DM42 3.9.1 on DMCP3.10:
I tried 1E4 on USB, ok.
I tried 1E4 on Battery, ok.
