cr1901 changed the topic of ##yamahasynths to: Channel dedicated to questions and discussion of Yamaha FM Synthesizer internals and corresponding REing. Discussion of synthesis methods similar to the Yamaha line of chips, Sound Blasters + clones, PCM chips like RF5C68, and CD theory of operation are also on-topic. Channel logs: https://libera.irclog.whitequark.org/~h~yamahasynths

Yes, the FTDI chip can be used to stream data, but only in UART mode
<cr1901>
the icestick does not provide the proper connections to stream data in the FT232's parallel mode
<cr1901>
Which means you're limited to 3Megabaud/whatever your OS can provide on a UART device
<cr1901>
endrift: What did you have in mind to stream?

cr1901: data off of a GBA
<endrift>
which has a UART mode, actually
<cr1901>
endrift: I wonder... is the GBA UART 8 data, no parity, 1 stop? Maybe you could extract the data w/ the GBA UART?
<endrift>
cr1901: I believe so
<endrift>
I might be able to
<endrift>
I'd have to look into it
<cr1901>
What are you trying to do specifically?
<cr1901>
(I'm actually awake rn for a bit)
<endrift>
right now, something I could probably do better with the Switch
<cr1901>
hmmm... guess I'll find out when you're ready to announce :P
<endrift>
it's nothing exciting
<endrift>
just doing some ARM7TDMI testing
<cr1901>
An FPGA might be useful for extracting timing info.
<endrift>
that's not what the FPGA is for in this mix
<endrift>
it's just getting the data streamed off of the device
<endrift>
so I don't have to swap flash cards all the time
* cr1901
has a horrifically yellowed glacier GBA from 2001 still.
<endrift>
with a Switch I could stream the data over USB
<endrift>
I just need to run the code on the BPMP
<cr1901>
Black Magic Probe?
<endrift>
basic power management processor I think
<endrift>
it's the bootstrap processor on the Tegra X1
<endrift>
Boot and Power Management Processor
<endrift>
I was close
<cr1901>
Ahhh neat
<endrift>
it just happens to be an ARM7TDMI
<cr1901>
So it's the ME of the Tegra
<endrift>
no that's TSEC
<endrift>
the BPMP is like if a separate processor did the real mode and UEFI bootstrap
<cr1901>
ahhh
<Lord_Nightmare>
doesn't a separate processor do pre-uefi bootstrap in a PC anyway, the IME?
<Lord_Nightmare>
(called something else on AMD but same idea)
<Lord_Nightmare>
i.e. setting up parts of memory, and emulating a TPM?
<gatecat>
I've got the feeling that quaintly AMD have and possibly still do used a LM32 core for some power management stuff too
<gatecat>
as well as an ARM or whatever for the main early boot
<gatecat>
~~will they switch to microblaze after buying Xilinx?~~

I have no idea how the early boot process works on x86
<endrift>
I think very few people do anymore
<Sarayan>
magic happens, then more magic happens
<Sarayan>
add crypto to taste
<cr1901>
gatecat: Ppl used LM32 for something :o?
<cr1901>
Don't get me wrong, I actually like it as RISC cores go. But i was not under the impression that ppl actually used it

can x86 start in long mode yet
<sorear>
a little disappointed long mode wasn't as well integrated as the 16/32 transition
<sorear>
give me a (necessarily long) prefix for REX functionality in L=0 segments, give me a 64-bit TSS and full support for call gates

gewt: kind of? it's possible to switch to it pretty early, but, well, apparently intel wants to preserve backwards compatibility with old-ass bootloaders...
