UPDATE: DMCP-3.10 / DM42-3.10

[akaTB]

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...

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

@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

[DA74254]

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.

[DA74254]

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.
