OpenGD77

Here is information to new developers on how to set up a development environment in Linux. Install lubuntu 21.04 Download MCUXpresso IDE from NXP and install it. cd Downloads/ chmod 744 mcuxpressoide-11.4.0_6224.x86_64.deb.bin sudo sh ./mcuxpressoide-11.4.0_6224.x86_64.deb.bin Run the IDE from Lubun...

There are at least two versions of Baofeng 1801 radios. One difference is flash memory size (1 Mb vs 2 Mb). Is that the reason for your problems? Though I can't imagine why firmware for smaller flash memory would not run with larger memory... Of course the codeplug would have to be reset when switch...

Is the interface to the "binary blob" documented in the code? Use the source, Luke! ;) $ unzip -v ~/Downloads/OpenGD77-master\(1\).zip | grep -i codec 0 Stored 0 0% 04-20-2021 08:55 00000000 OpenGD77-master/docs/technical_documents/codec/ 1556670 Defl:N 1488628 4% 04-20-2021 08:55 d78978f9 OpenGD77...

I think Andrew has got the spirit of open source software and collaboration-- and licensing, as far as GPL goes-- in the right interpretation. It's about freedom as in free speech (freedom to distribute, build, enjoy) and not necessarily freedom as in free beer. I agree. Open source gives you freed...

The power of true open source is that an open source project never dies. The development may freeze for a moment, but as long as there is the source code, anybody has the possibility to continue. OpenGD77 is an excellent piece of software. Sooner or later it will catch developer interest. Nothing pr...

The other thing I don't know, is the compile size of codec2. There is not much space remaining in the MCU ROM.

What about the 2 Mb version of DM-1801?

DM1801 has two distinct versions: 16CH/Zone, 32 zones, 1024CH total . 1M flash units and/or old FW, i guess? uses DM-1801 CPS 32CH/Zone, 150 zones and 3000 total channels . the version i have, 2M chip and 2.2.1 fw. user manual on FCC site is for this one as well. the only working cps for this versi...

Is it really a problem to distribute OpenGD77 firmware file (the .sgl file) which contains the AMBE codec ("the blob")? The sgl file is encrypted, so it is usable only on a supported radio. You can't extract the codec from the sgl file. And if the radio contained the same version of the official fir...

The software license requries you to supply all sources for your release. But isn't the BLOB a system library? If not, why not? At least it is used like a library, via the wrappers? And everybody who has the radio already has a copy of it in the flash memory? http://www.gnu.org/licenses/gpl-faq.htm...

Many thanks ! I just did git pull, started the compile, and... 0 Errors, 0 Warnings... So immediately flashed it, and ... it works! Good to hear that! Many thanks to Roger, it is because of you that I started using OpenGD77! You have done impressive work! The difference between CB users and radio a...
