Re: Pi-Star Build for x86?

The board I have is from repeater builders and he makes two models one GPIO and one USB :) I will take a look at what you suggested; thanks for the info. I’m not really a great coder but I am a cloud systems engineer with heavy focus on hardware architecture & storage solutions. I have done a fa...

Pi-Star Build for x86?

Hello Pi People :) I was just curious if any thought has been given to compiling a pi-star distro for x86 based systems? With the on going and EXTREMELY crazy price of raspberry pi's; it just does not make any sense to spend $200+ US dollars (if any in stock at all) JUST for a pi. Given that you can...

Re: SMT32 board & FSK error rate

I think I have found the answer! I keep forgetting on these Kenwood repeaters its used the serial/data line. Those values can and seem to often need to boosted to get the deviation to be set right: Depending on the existing configuration of the repeater it may be necessary to adjust the TXD and RXD ...

Re: SMT32 board & FSK error rate

Yeah, this is connected to a TK-740 VHF repeater (on-site, it has a high power amp) but makes sense figured worth asking at least :) I know the bulk of users are using Pi-Star based HotSpots so my question is "out in the weeds" so to speak. DMR is just really picky being TDMA vs FDMA. The ...

SMT32 board & FSK error rate

Hey Gents - Going to do my best to try and relay this issue. So a buddy whom is an RF engineer connected up his digital service monitor so we could try and DMR adjusted for a repeater using the STM32. No matter what we seemed to try we couldn't get it into spec. The magintude was soild but FSK error...

Re: ZUM Radio - MMDVM-Pi rev. 1.0 board firmware update

I found the solution! Toss the @#$%y thing in the trash and get new hat from RB lol. Just kidding, I didnt toss it but I did just order a one from RB. Set several of those up didn't give me nearly as much trouble plus he publishes pre-built binaries for updates when/if I feel adventurous to compile ...

Re: ZUM Radio - MMDVM-Pi rev. 1.0 board firmware update

So, here is something interesting. Started fresh, followed the guidelines I setup but minus replace the stm32flash & using the other hash you mentioned. When doing the deploy it errors out: root@pi-star(rw):MMDVM# sudo make deploy-pi-f7 /usr/bin/stm32flash -i 20,-21,21:-20,21 /dev/ttyAMA0 stm32f...

Re: ZUM Radio - MMDVM-Pi rev. 1.0 board firmware update

Thanks KE7FNS some good things to try there. Yeah, I know what you mean about troubleshooting and not having the hardware. Ran into that more than once in my career.

I'll give those a shot and report back :)

73!

Re: ZUM Radio - MMDVM-Pi rev. 1.0 board firmware update

So here is where my "I am not a dev" question comes, how do I get the roll backed version assuming from github? Yeah. From the command prompt. rpi-rw cd MMDVM (or whatever directory your MMDVM source code is in) git checkout 9c883cfafdb183da01d888b67f2803f13698653f git submodule init git ...
