  • WARNING 1.92 & 1.93 reboots on dx label add [fixed in v1.194]

    Yep. An unfortunate bug that was introduced but then masked by some other unrelated debug settings that were removed later on. So it passed all the testing. Fix coming in today's update.

  • v1.190: keyboard shortcuts, IQ display mPSK, FAX alignment, DX label features

    jksjks
    Lots of changes.

    Keyboard shortcuts is a work-in-progress. Press "h" or "?" on your keyboard. Feedback requested, especially from our visually impaired users.

    The mPSK stuff needs a separate discussion. Try QPSK mode with VLF MSK or LF DGPS signals and 8PSK mode with strong, non-fading STANAG 4285 signals on HF.

    FAX: the entire image will now align on shift-click including the part of the image already received. On mobile devices a touch on the image will cause an align.

  • v1.188: switching compilers from gcc to clang

    jksjks
    Today's update switches compilers from gcc to clang. This means in the future update builds will run about twice as fast.

    But today's build will take some time as the new compiler is downloaded and installed. Total update/build time will be approximately 15 minutes.
    It is extremely important that you do not interrupt this process and potentially leave your Kiwi in a partially updated state unable to run or update further (i.e. "bricked").

  • kiwid restarts after assertion failure in support/coroutines.cpp [fixed in v1.184]

    jksjks
    Thanks for reporting this. As you can see I added some additional debugging in the latest release (the "ca_pause -1594 ..." stuff).

    I added the assertion a little while ago to make sure a hardware (FPGA) constraint wasn't getting overrun. If it is then a sat that is acquired may not be tracked properly. And we see this behavior sometimes. But this assertion has never occurred in my testing (or at least I've never caught it happening). So if I can understand what's going on and fix a bug this might result in greater tracking successes which would be very helpful.

    Okay Ivan, I've got a fix running on your Kiwi and so far it looks good. I was able to write some test code for my Kiwi that caused the assertion failure to occur. So I'm pretty sure that the bug I fixed is really the source of the problem. I'm not sure why it happens so often with your Kiwi. The problem occurs when the GPS acquisition task is started and stopped as the number of user connections changes between zero and greater than zero. That is the only case that uses a special case of the coroutine task sleep/lock code.

    I'll include this fix in the next update.
