Re: DM42- clock losing time

Is it possible to realize a software-based time correction on DM42? HP-41CX has a very good RTC. My 41CX loses only 0.2 sec a day with its default setting. Furthermore, it has functions to correct its time according to its actual accumulated time errors. As a result, the time error of my HP-41CX is ...

Activate USB Disk" seems to work, but "DM42_qspi_3.1.bin" file cannot be copied there. How do you know that "3. Activate USB Disk...

Then I tried to update DM42_qspi_3.1.bin using dm_tool, before I realized that the update was not necessary. I should not h...
