Topic: Div2k14, how to update?

Hi,
I do have a div2k14 from Loratek.

I do have two questions:
1) it's suposed to be DIVIDE (and not DIVMMC), right?
2) It has esxdos 0.8.5. I set the jumper settings for updating, and launched the DIVIDE.TAP file, but it ends with an error. Maybe I can't update it from the EsxDOS loaded itself? I should move to another firmware before updating? Is there any trick for it?


Thanks!

Re: Div2k14, how to update?

Maybe you need Velesoft’s EPROTECT utility as can be found here: https://velesoft.speccy.cz/zx/divide/divide-soft.htm

eprotector

btw. Should be a divIDE. Is it looking like this?:
d2k14b

Info: https://lotharek.pl/productdetail.php?id=71

Two different setting for flashing jumper are described in manual:

What error message is shown when you try to flash?

Re: Div2k14, how to update?

In regards of switches:

I used Firmware selector:

Left DOWN, RIGHT UP (ESXDOS)

and DIVIDE MODE SETINGS:
Left UP, RIGHT UP (+2A spectrum)

Then loaded the .TAP file.

And then (again, DIVIDE MODE SETINGS):

Left DOWN, RIGHT UP (DivIDE system is disconnect, enable reflashing eeprom)

Which other mode is present for flashing?

And this was the error.

I should try the utility, then I guess.

I tried the eeprom protection Utility (divmmc_eprotector.tap), it says set JP2, press reset (reset on the spectrum, right?) but, same error when trying to flash ESXDOS:
CANNOT FLASH.

divMMC? Probably the wrong EPROTECTOR-Utility....

There´s another one for divIDE on Velesofts page, please try this: https://velesoft.speccy.cz/zx/divide/so … divide.zip

So far, I think, these Jumper-settings should be OK.

Maybe the Flash-File had to be loaded from real "Tape-In"-Connector.

than run utility and do unprotect.
Than do a Warm reset (No Hard Reset).
Than load new esxDOS-version from real "Tape-In"-Connector and try to flash.

btw. Have you asked Lotharek about it?

Yes, I just sent today the question to Lotharek.
