UPDATE: DMCP-3.17 / DM42-3.15rc1

Post by grsbanks » Tue Feb 18, 2020 12:05 pm


It's been a while since the last update for the DM42 but here we are.

This is a Release Candidate that we'd like to let you test before it is committed to "Production" status. Please note that this is not a beta release, it is already tested extensively, which is why it's a Release Candidate.

Full details are available here: https://www.swissmicros.com/dm42/firmware/history.html but suffice it to say that this is an update to DMCP and Free42-core is updated to v2.5.16.

As usual, you can find the update procedure in the manual and the firmware itself is available here: https://www.swissmicros.com/dm42/firmwa ... .15rc1.bin
There are only 10 kinds of people in the world: those who understand binary and those who do not.

I updated my DM42 and took a quick look before going to work. Confirmed WSIZE and the ASTO and GETKEY fixes.

Did anything change regarding state files?

The update was flawless. I tested all my programs with it without any problem.

Thank you very much for the update.

So, at some point will there be another release for “production” ? And if so, will the current version of Free42 be incorporated ? As I write this, Free42 is now at version 2.5.17, and will no doubt continue to be revised as TO finds new bugs and makes new improvements.

Free42 is at 2.5.17 now, but it is still at 2.5.16 for Android, which is the same version here for the DM42, so I do not think that the chnages from 2.5.16 to 2.5.17 effect anything in the DM42 application of Free42...

None of the changes since 2.5.16 affect the DM42. Most of them are OS-specific changes for iOS and MacOS, and 2.5.17a will have more changes for iOS and Android. The only change to the simulator core since 2.5.16 is a fix for a memory leak in core_paste(), and that function is not used by the DM42. So there's no need for SwissMicros to merge in any further Free42 updates, for the time being.

There is an issue with rc1, not able to read portable state files from other devices/platforms. The problem has been identified and a fix is in the works, and will be available shortly.

Recommendation: Wait for rc2, unless you'd like to explore other features that have changed in recent Free42 builds other than using portable state files and then upgrade again to rc2.
