Bhyve: #FreeBSD Virtualization

https://vermaden.wordpress.com/2023/08/18/freebsd-bhyve-virtualization/

Each #RISCV Core in #JH7110 can be programmed individually to receive Interrupts ... In Machine or Supervisor Modes

Hahaha, I can see that... but I do. The one thing that happens when im not on meds is i spread myself too thin doing too many things at once while following through on none of it. On the meds I get stuff done and tend to focus on one thing at a time, I just get very frustrated.

On the drugs ill follow through on something and it will be mediocer... off the drugs i wont follow through on any project but ill have 100 brilliant ideas.

Usually if i dont have a 9-5 ideally ill go through cycles on and off. When off I come up with ideas and take notes, and when on it i pick an idea and follow through, rinse repeat.

The sweet spot for me is 1-2 weeks on it. In that case I am hyper focused, no frustration, Its the sweet spot.

Testing #RISCV Star64 #JH7110 SBC with Apache #NuttX RTOS ... Thanks to TFTP 👍

Here's the answer: UART Registers on Star64 #JH7110 are spaced differently from QEMU!

I am completely new to this world. Everything I know is from the internet - hamstudy.org & YouTube primarily. The prospect of communicating with satellites is thrilling to me! I'm also interested in the "surival" uses of alternative forms of communication. #introduction #ham

I am making tons of progress on my #OSS . #FOSS APRS project called #Digipex.

I got an igate relay hosted (this will be neccesary to ensure we can get dup packets):

https://igate.digipex.io

I got a web-app going that will display allt he clients on the map and give some statistics/status info:

https://hub.digipex.io

I also have the most important part, working code that talks to the radios and routes / rewrites packets. Right now it can send/receive, digipeat, and gate to and from the igate.

The code for digipex is here: https://git.qoto.org/digipex/digipex

And you can see some information about my particular digipex node here:

The picture below is of a microcomputer (like a raspberry pi, its a khadas) running digipex and showing the packets it deals with on the miniature screen.

#NuttX Shell runs OK on #Star64 JH7110 #RISCV SBC! 🎉 ... But 16550 UART Controller fires too many Spurious Interrupts ... Each Dot = 1 Million Interrupts! 😲

Just saw some minor VHF skip or something... my beacon just traveled 155 miles to virginia from my roof... thats unusually far for 2m VHF....

Burns: Well, everybody knows, ‘war is hell`

Hawkeye: War isn’t Hell. War is war, and Hell is Hell. And of the two, war is a lot worse.

Father Mulcahy: How do you figure that, Hawkeye?

Hawkeye: Easy, Father. Tell me, who goes to Hell?

Father Mulcahy: Um, sinners, I believe.

Hawkeye: Exactly. There are no innocent bystanders in Hell, but war is chock full of them – little kids, cripples, old ladies. In fact, except for a few of the brass, almost everybody involved is an innocent bystander.
