▶SiFive HiFive1 and RISC-V Anonymous 07/11/18 (Wed) 23:10:24 No.941353>>941392 >>942057 [Watch Thread][Show All Posts]
I was thinking of buying a HiFive1 board. It has the same form factor as an Arduino, but has a RISC-V microcontroller, and is a lot faster than the Arduino Zero. But, it cost 60$.

Should I buy one?

$60? Who cares. Use the stickies next time.

Jesus, that CPU is tiny.

This shit still isn't libre yet. Don't get jewed.

Au contraire, if you deny yourself access to technology that you want for an autistic jew's philosophy, consider yourself jewed.

HiFive1 is libre, the linux compatible one is the one that's not libre.

Ok

Fffffuck
I'll need to find some other autists near me to spread the shipping costs.

Not all technology respects your freedom. If you believe that freedom is important, then it is important to judge technology by how much it respects you, the user who bought the technology and is using the technology to achieve practical work.
If freedom is not an important part of your life, then the only reason to reject technology is because you have no use for it.

i don't know which one is the actual CPU, but from the number of pins, this can't be more then 8 bit, maybe 16 multiplexed.
thats basically an Arduino, for 60$

The microcontroller is the chip with a big 5 on it. Read the specs, it’s a 32 bits RISC-V MCU, at a speed of 320 MHz, compared to 16 MHz for most Arduinos. I don’t really know why you think one can determine the architecture of a MCU from the pin number (pic related is an 32 bits ARM MCU).
▶Anonymous 07/12/18 (Thu) 13:24:55 No.941570
so, is this a single core mcu?
i know its novel and appealing but kinda stiff on the pricing when an esp32 is a dual core @ 240mhz (and yes i know the arduino crowd might not be the desired crowd, jsut saying)

Not talking about the internal architecture but the bus width, you can have a 128bit CPU if it only has 8 bus lanes its gonna be seriously crippled. And won't be able to do much more then an Arduino.

How does bus lanes == crippled? PCI-e can push 500MB/s per lane using only 4 cables (2 LVDS pairs). Yes you won't be running SLI Titan X using that board, but it's not by any means seriously crippled. There is enough power to run some sort of video output and simple OS.
▶Anonymous 07/13/18 (Fri) 16:01:05 No.942057>>942118
Are there any distros with releases for this thing?

This is the HiFive1, an Arduino-style device. You're not gonna see any real Linux running on it.
For the larger system, look at the HiFive Unleashed.
I hear Debian and Fedora are working on Risc-V compatibility, as are the BSDs
