Ah yes. You are correct. Than it’s 4 Gbits/s
ROCK 5B Debug Party Invitation
That’s for m.2 to x16.

Based on rk3588 schematics I believe that one lane of pcie 2.1 was taken by RTL8225BG.
And Allen is talking about making 1 Gb/s port, but having 2 lanes on e-key pcie (not like i agree with it, since for mass-market it’s more important to have 2.5G and placement for wifi, rather than going for ~10Gbit on single port)

Radxa could’ve gone with GbE by using one of the two GMACs RK3588 provides. But fortunately they didn’t (see @willy’s insights above – RealTek really improved a lot over the last decades, even the 8111 PCIe NICs are fine starting with revision G).
I hate to quote Stuart but ‘it is as it is’ and they chose better network connectivity over another disposable Gen2 PCIe lane.

@Dante4 I have also seen a few adapters like those but since there are no visible chips on them (and they are very cheap) I would assume that they are just x16 slots where only the first four lanes are connected to something. Hence if I put an extension card there that expects/requires 16 actual lanes, it will not work as expected 
Maybe I just try the port multiplier solution and hope for the best 
if the worst case is that the last written data might be corrupt, I don’t care…
Thanks for your help guys!

No, that doesn’t work like this. As you may see in my post - I used PCIe switch, and that worked perfectly fine. Any (and by any I mean ANY) pcie device ALWAYS detect pcie version and amount of pcie lines available to it. So if you input x16 device in x4 lanes - device will go down to x4 lanes

@willy I found another funny PVTM example (part of sbc-bench results collection): http://ix.io/47IO

For whatever reasons highest cpufreq OPP is 2352 (maybe configured manually by tweaking DT) but this results in some MCU declining high clockspeeds totally and limiting the upper end to below 400 MHz

PVTM at work 
That’s extremely strange. I’m more eager to thinking that there was a measurement error, e.g. opp being reported at some point and for whatever reason the idle calculation went wrong and the frequency instantly dropped to the lowest value during the measurement, or something like this. Or maybe this was run with the CPU overheating, causing it to instantly drop to the lowest bin during the test. But I do not see this being the result of a mistake in that non-fully-transparent chain, because the sel values only select an OPP entry and if your OPP is correct it should set the appropriate frequency. Or maybe the opp entry was slightly modified and the cpufreq code, not finding it, went to the lowest, but that sounds fishy.
I would believe we’re seeing cpufreq driver and one of those Cortex-M cores responsible for CPU doing different/counterproductive things?

The next step is to encode the stream to mp4.
What about a loop back? Grabbing frames from Rock 5B hdmi out to hdmi in? Yes, it works.
Hardware Encoding (H264) takes ~2% CPU usage (1.3% ~1.7%). Finally, a platform where you can make videos with HDMI input. Worked well with FHD at least. 4K not tested. Maybe I’ll find a 4K TV and try it out.
I am using the default mpp parameters, you can set “gop reference mode”, “bps” and “frame rate”, but that is for the video encoder experts, if you want me to try with some parameters, let me know.
Here is the encoded output (1920x1080, 60 Hz, 30 fps, 600 frames)

Rendering the BGR frames with SDL. Not really optimized, the best option would be to use NV12, i haven’t found a way yet, any suggestion?

@hipboi,@jack,
Please, consider providing an option for buying a camera FPC with a length of 20 cm, 25 cm, or maybe 30 cm for robotic projects. Can you share if the final product will have a different flex cable? I can see you are preparing for new camera sensors.

Presumably one could also use a cheaper board based around the ASM2812, like this:

Progress is being made on replacing the GPU firmware…
root@rock-5b:/sys/kernel/debug# echo 'Hello, World!' >mali0/fw_traces
root@rock-5b:/sys/kernel/debug# cat mali0/fw_traces
Hello, World!
So I can now send and receive messages from my firmware image through tracebuffers.
Unfortunately I’m having problems with getting exception returns to work, so I have to use polling rather than waiting for an interrupt.
Does anyone with experience with microcontrollers have any idea why an exception body that is nop; bx lr with 0-3 NOPs works fine, or 16-19, but not 4-15 NOP instructions?
i.e. the return instruction faults if it is not in the first eight bytes of a cacheline.
I’m defining the function like this:
__attribute__ ((naked, optimize("align-functions=64")))
static void
irq_handler_doorbell(void) {
asm volatile(
"nop \n"
"nop \n"
"bx lr \n");
}
The fault shows up in dmesg like this:
[ 4582.644400] mali fb000000.gpu: Unexpected Page fault in firmware address space at VA 0x0000000000FFFFE0

I would like to report an issue. I think it’s been thoroughly discussed here, but since I haven’t stressed the board enough, I’ve never had this issue, until now.
My board has the exact same configuration (and batch number) as that of @CNXSoft.
I have been doing the builds natively (deb packages), using the eight cores. The builds are usually small, and i don’t cross-compile the apps i am testing. In fact, i have some linkage errors that a rockchip staff member could not reproduce, but maybe this is not related to the issue.
To make it short, since my kernel was somehow old, i cross-compiled the kernel with the latest patches and booted with the new kernel. Later, i decided to build the kernel natively. during the build, the board started to slow down, and the build crashed. (core dump). There was no overheating. I had to reboot the board. Unfortunately, eMMC got corrupt and the fs could not even be restored (no partition anymore).
I am using the radxa power supply.
I think these patches may have something to do with the issue (not really sure):
Can someone share what can be monitored in /sys so i can try to add it to htop and see the values in real-time? I will remove the patches and redo everything and see what i get.
Maybe the 64GB DRAM timings need to be addressed?
UPDATE:
Here is what is left from the 64GB eMMC that came with the board:

Can you use PipeWire instead of PulseAudio?
I really only have experience with Gentoo on x86_64, and had all sorts of audio issues with PA, but switching to PW fixed everything.

Is PipeWire available on Ubuntu for arm64?
Yes, i will try it.

Not sure i followed the recipe correctly (they all use ppa), looks like i missed something:
sudo apt-get update
sudo apt install pipewire (pipewire-audio-client-libraries not available)

I want to know what desktop environment is this with such a low memory footprint
我想知道内存占用这么低的桌面环境是什么
Same symptom as overwriting the rootfs with /dev/uramdom. Everything slows down and then the install freezes/crashes (I sometimes do this for fun when phasing out server hardware).
I would believe you experienced a broken eMMC module where the flash controller did weird things. Most probably neither related to board nor software.
