Flashing the DM-15CC - Geoff Quickfall - 01-02-2013 Hi and happy new year. Left Hong Kong on January 1st, 2013 at 8pm and arrived in Vancouver at 8pm on December 31, 2012. Felt like Dr Who... ;-) Any how, was trying to flash the DM-15CC using Flashmagic and the CP2102 driver (installed of course). Followed the instructions to the letter: I get the following message on the calc LCD: "PR ERROR" and the following windows message: "Failed to read the device signature (Operation Failed, (reading Signature)) Accessing the drive using the wrong signature could render the device unusable." My system is Windows XP and com 3 which is available. any ideas?

Re: Flashing the DM-15CC - Etienne Victoria - 01-02-2013 Geoff, Since the first production batch, the chip has changed. Any chance you have a calculator from the first batches ? If yes, the chip to setup in Flash magic is LPC114/302 If you have the latest model, I have no further idea. Best

Re: Flashing the DM-15CC - BobVA - 01-02-2013 Geoff: I had exactly the same issue, which turned out to be dated flashing instructions in my case - I think they've upgraded the processor to a different model. I wound up opening the calculator, reading the processor type off the chip label and selecting that from the menu.
Cheers,

Re: Flashing the DM-15CC - Geoff Quickfall - 01-02-2013 your right, after all these years, that damn dateline!! Left December 31st at 2100, 3 hours later in Hong Kong it was January 1st. We crossed the dateline 6 hours after departure, so we had 3 hours of January 1st before we crossed the dateline heading east. Once across we were back to December 31st again. Arrived in Vancouver at 1800 on the 31st of December. Had to really think about that one!!! Geoff
still felt like dr who in any case.
Re: Flashing the DM-15CC - Geoff Quickfall - 01-02-2013 yep, the first batch that i have is LPC1114F/302 which is 1114/302 in Flash magic I will give it a try after dinner and post. The titanium model gives the same error message and I have not opened it up yet.
Cheers, Geoff
Re: Flashing the DM-15CC - Christoph Giesselink - 01-02-2013 I had the same problem with my DM-15CC (2nd batch). Also on a XP system. To verify the USB interface hardware of the DM-15CC and the CP2102 driver installation I called the serial console [ON]+[C]. The console worked propely in connection with the DM-15CC. Second I tried to update a DM-16CC on the same computer, which also worked properly. So it was clear that my system was ok. Then I contacted Michael Steinmann and he told me, that some devices have had problems with the solder connection of the PGM button. With a binocular loupe was was able to verify a cold solder connection at one pin of the PGM button. I fixed this with a soldering iron and then I was able to update the firmware.

Re: Flashing the DM-15CC - Lyuka - 01-03-2013 The DM-15CC of second batch I bought in November last year uses NXP LPC1115F/303.

Re: Flashing the DM-15CC - Christoph Giesselink - 01-13-2013 There's no java ROM dump script on the SwissMicros side, but I'm sure that there's a program for a "RAM" ! dump of a DM-15CC memory. The RAM dump mode is accessable over the serial console mode by [ON]+[C]. The PGM button is only necessary for a firmware update.
Finally read the instructions on the SwissMicros page carefully, I'm sure the page tell "set terminal program to 38400,8n1 (no flow control)" and nothing about XON/XOFF as control flow.
Re: Flashing the DM-15CC - George Litauszky - 01-13-2013 Ok,thanks.
