[02:51:06] <kreyren2> Tsvetan: how long do you think it will take to make a SBC for RK3588?
[10:46:29] <Tsvetan> kreyren2 we have no ambitions to make OSHW for every new Chinese SOC with binary blobs and proprietary Android kernel which pop on the market
[10:48:01] <kreyren2> hmm O.o oke
[10:48:11] <Tsvetan> right now Im looking around for RISCV running Linux as it seems some started to appear and orderable, Like RZ/Five from Renesas and D1-H from Allwinner
[10:48:30] <kreyren2> O
[10:48:39] <Tsvetan> RZ/Five can address up to 4GB DDR4, D1-H up to 2GB DDR3L
[10:48:58] <Tsvetan> RZ/Five has 2 native Gigabit Ethernets
[10:49:25] <Tsvetan> and will make perfect headless server for Home Assistant, FreedomBox, NextCloud etc
[10:49:40] <kreyren2> O
[10:49:40] <Tsvetan> too bad it has no SATA
[10:50:41] <kreyren2> Seems to have just one core at 1Ghz though.. might be great for a phone
[10:52:29] <Tsvetan> no display
[10:52:35] <kreyren2> ahw :c
[10:52:41] <Tsvetan> this is made for IoT gateway/server
[10:52:52] <kreyren2> I see O.o
[10:52:57] <Tsvetan> but D1-H has HDMI and video/GPU
[10:53:07] <Tsvetan> although only 2GB
[10:53:27] <Tsvetan> but I'm optimistic mor and more RISCV will come up in the next months/years
[10:54:06] <Tsvetan> I dont want to lose resources for RK3588 it's nothing more than iMX8 we already have designed
[10:54:31] <kreyren2> for me currently gnome apps and websites take a long time to load which is probably caused by the slow eMMC and it's not as good at decoding to do game streaming
[10:55:05] <kreyren2> would be cool to have cluster servers too though 🌟_🌟
[10:55:08] <Tsvetan> yes, software becomes more resource hungry every year
[10:55:18] <Tsvetan> A64 used to be decent 5 years ago
[10:55:19] <kreyren2> so that i can like build software and have a beefy homeserver
[10:55:42] <kreyren2> it seems to be decent i probably just need to change the eMMC bcs it's much snappier on the sdcard
[10:56:12] <mps> Tsvetan: what about starfive JH71xx SoC
[10:56:46] <kreyren2> did they release the docs for it yet
[10:58:28] <mps> I've got JH7100 SoC, starfive visionfive v1 board from riscv foundation in May and I'm experimenting with it when I have free time
[10:59:04] <kreyren2> Beagle has an OSHW designs for it no?
[11:00:06] <Tsvetan> mps who is selling JH7100 chips? I check and there are just boards on Amazon
[11:01:07] <kreyren2> afaik StarFive is selling them on inquiry or so i was told
[11:01:15] <kreyren2> ACTION was looking into that chip for his phone design
[11:01:54] <mps> Tsvetan: JH7100 is/was just development release and produced in small quantity for developers, I think not intended for mass production
[11:02:16] <kreyren2> like pine64 is going to mass produce star64 with that chip no?
[11:02:19] <mps> JH7110 is probably successor for masses
[11:02:23] <Tsvetan> mps :)))
[11:03:05] <Tsvetan> both RZ/Five and D1-H are active and available
[11:03:33] <kreyren2> weaker though JH7100 has dual core based on the datasheet
[11:03:34] <mps> Tsvetan: idk exactly their plans, I've got offer from riscv foundation to port alpine linux on it and I did it
[11:04:39] <mps> it is good for me to get 'fingers dirty' in riscv and learn about it
[11:04:48] <Tsvetan> and there is ESP32-P4 coming but it will be low performance at Dual core @400Mhz and PSRAM QSPI Flash like on other ESP32 modules, but I bet they will beat all others at prices and will target RP2040-PICO market
[11:05:20] <Tsvetan> i.e. RTOS embeded apps
[11:05:40] <kreyren2> might be good for my LinuxCNC
[11:06:11] <mps> JH7110 is four core ant 1.5GHz and have m.1 interface, hdmi, 2 eth, up to 8GB ram, CAN and other interesting peripherals
[11:06:11] <Tsvetan> my feeling is that by the end of this year there will be capable and available RISCV linux SOCs from multiply vendors
[11:06:28] <bill-auger> Tsvetan: ive made some changes to the teres manual - i will offer it eventually; but i have a question
[11:06:33] <mps> s/ant/at/
[11:07:05] <kreyren2> Tsvetan: did you see https://github.com/OLIMEX/DIY-LAPTOP/issues/55 yet? ^-^
[11:07:43] <mps> also, maybe I will get JH7110 visionfive v2 board in near future
[11:07:46] <bill-auger> i am trying to describe the LED indicators; but im not sure what the indicator with the battery icon does
[11:08:15] <kreyren2> it's blinking red when it's discharging afaik
[11:08:31] <bill-auger> it becomes lit red when the battery is charging; but is it always red?
[11:08:38] <kreyren2> and solid red when charging
[11:08:48] <kreyren2> seems to be
[11:08:52] <bill-auger> or is it only to indicate that it is running on AC power, not necessarily charging
[11:09:01] <mps> and I see active linux kernel upstream patches sent
[11:09:07] <bill-auger> ive not seen it blink
[11:10:11] <kreyren2> seems to be:
[11:10:11] <kreyren2> * solid red = charging
[11:10:11] <kreyren2> * blinking red = battery below ~95%
[11:10:11] <kreyren2> * blank = battery above 95%
[11:10:30] <bill-auger> mine is not behaving that way
[11:10:37] <mps> side curious note, I use power supply bought from olimex to power visionfive v1 board
[11:10:52] <kreyren2> mine's running armbian.. might be their thing then O.o
[11:11:05] <Tsvetan> bill-auger it's LED connected to AXP803 CHARGE pin https://linux-sunxi.org/AXP803
[11:11:37] <Tsvetan> kreyren2 I saw this but we use ready made plastics so changes are not possible we have to stick to the existing plastic
[11:12:24] <bill-auger> IIRC it is on stready red when the AC is plugged in, regardless of the battery charge, and off when running on battery
[11:12:46] <kreyren2> hmm fair.. what about that UEXT and adjusting SBC designs though
[11:15:04] <kreyren2> or like using a different case for the next design that allows the modularity or adjusting the current mainboard to have snap points that can be replaced with a flexible wire 🌟_🌟
[11:15:04] <kreyren2> .. point being compatibility with non-slimbook cases
[11:16:43] <kreyren2> bcs that dirt bag in our hackerspace is keep flexing on me with his custom intel system using magnesium system78 case
[11:18:35] <bill-auger> kreyren2: do you know which baord revision you have - maybe different behavior is expected?
[11:18:42] <kreyren2> Rev.C
[11:41:00] <kreyren2> ACTION uploaded an image: (3142KiB) < https://libera.ems.host/_matrix/media/v3/download/matrix.hyron.dev/yg1GsXp6N5eKrKVHehuLT7WgueCNMR0U/image.png >
[11:41:10] <kreyren2> Lemur Pro might not be a bad case for teres
[11:42:55] <kreyren2> basically very similar to the one we use now just slightly bigger and with common battery and stuff
[11:43:03] <kreyren2> https://tech-docs.system76.com/models/lemp11/external-overview.html
[11:45:37] <kreyren2> Tsvetan: ? :P
[11:48:38] <kreyren2> ACTION uploaded an image: (937KiB) < https://libera.ems.host/_matrix/media/v3/download/matrix.hyron.dev/LScEjwh0hHCTKXPahfu9F2QdwR9YqbPG/image.png >
[11:52:25] <Tsvetan> looks very similar to TERES plastics
[11:52:34] <kreyren2> mhm
[11:53:19] <kreyren2> teres-next case? :P
[11:53:35] <kreyren2> with enough space for the modular design? 🌟_🌟
[11:59:40] <Tsvetan> hmmm
[12:02:02] <Tsvetan> I would like better aluminum case like on Asus Zen Ultrabook https://nixanbal.com/media/k2/items/cache/ca8a8af3931a821b4cde4c35f3194ee4_L.jpg
[12:03:10] <kreyren2> i prefer magnesium bcs it's lighter and doesn't have that issue of temperature soaking (to have a common feeling of coldness on touch)
[12:06:39] <kreyren2> or like at least magnesium is much more comfortable for me to hold O.o
[12:07:12] <kreyren2> though i don't mind as long as it enables modular design so that i can make my own case for it xD
[12:20:47] <bill-auger> i may have found the difference - the datasheet says the LED can be in two modes - one mode is on or off (charging vs not charing) - the other mode blinks while charging - there seems to be a third mode, which can be controlled manually by other pins
[12:26:19] <kreyren2> o.o
[12:26:48] <bill-auger> oh not other pins, by internal registers
[12:27:43] <bill-auger> linux is identifying it differently than the sunxo wiki though
[12:29:55] <bill-auger> like /sys/class/power_supply/axp20x-battery/ - mine is showing it as axp81x
[12:30:55] <kreyren2> i can't check now.. tsvetan is in the battle to convert windows pleb on freedom lover atm
[13:01:36] <kreyren2> <bill-auger> "like /sys/class/power_supply/axp..." <- bill-auger: mine shows axp20x-battery
[13:01:47] <kreyren2> so hypothesis is that you have the revision B
[13:09:47] <kreyren2> Hmm
[13:09:48] <kreyren2> Revision B has AXP803
[13:11:41] <kreyren2> AXP81X is probably rounded AXP803
[13:11:43] <kreyren2> ACTION grins hard
