We are running on a early version of ROCK5 board 
A76 2.4GHz x 4
A55 1.8GHz x 4
ROCK5 Android12 Bringup Status Update
I’m curious if it would be faster if only big cores are used.
./benchncnn 10 4 2 -1 1
Still didn’t have a heat sink maybe faster ddr4? Or did they go all out with ddr5 
Also does benchncnn run on the Mali as the vulcan drivers seemed to be inplace, still can not see the GPU being faster than the NPU as 6ToPs is quite a lot but would be interesting as have never had my hands on one of the new G610s or any thing above a G31
Would it be possible to get a dump of /proc/cpuinfo? I’m curious what revision of the Cortex-A76 IP the RK3588 uses (so the variant and revision fields are most important).
Thanks!

I can’t find my tiny fan, so I run it without a cooler this time.

Excellent! Rockchip has integrated the r4p0 revision of Arm’s Cortex-A76. This means we get support for the PSTATE Speculative Store Bypass Safe (SSBS) bit and the speculation barrier instructions that got introduced in the Armv8.5-A extension. (This was actually introduced in r3p0, but generally the newer the better.)
They also used the newest revision of the Cortex-A55 - r2p0.
Thanks for dumping this @anon39001862!

Cool I will have to take your knowledge of revisions for that but great.
Guess with the TMSC vs Samsung, 7v8 nm we ended up with Samsung so likely do clock a bit slower but that is whoever Rockchip could get fab with due to current situation so no biggie.
Would be great if that heatsink/fan does ever turn up just to see if there is any thermal throttling in the above as always a good indication of headroom.
PS a 12v fan on 5v or 5v on 3.3v works great and doesn’t sound like a mini hairdryer.
I am wondering though if the MCU’s have blobs that might lock cpu frequency like the amlogic a311d does as Rockchip does seem to be more opensource friendly than amlogic but could even be a arm blob.
PS with revisions loving the pico-itx format as its like its big brother the PC having I/O on one plane is very easy and flexible.
The mini usb on the side is PD power? As no problem as an extension cable is easy and cheap but the boot & reset switches would be more fexible if just simple jumpers as for cases / racks / relays it just creates more and simpler options.
Also allows you to put a simple harness in the shop for that but wow it should make sourcing racks and cases and implmenting them so much easier and also you could use a remote realy.
If its all on one plane or vertical via extention its just such a sweet layout.
How to load m0 cores with binary files? Can we do this in system or have to use jtag port? By the way, I’m curious about whether the jtag port for cortex-a/m cores have been connected to outside pins. Jtag/swd would be very useful for developing m0 cores.
| Cool I will have to take your knowledge of revisions for that but great.
Thankfully you don’t have to take my word for it - Arm does a good job of documenting what changes for each different revision in the TRM (Technical Reference Manual) for each core IP.
So, in the case of the Cotex-A76 you can find the TRM for the latest revision here:
https://developer.arm.com/documentation/100798/0401/?lang=en
and in the “Product revisions” section, A1.7 in this case, you’ll find all the details.

Nah I will just take your knowledge of the revisions as means littlle to me.
I was just curious if the MCU blobs are locked or not, purely wondering if community OC is possible as wondering if its locked.
Not a biggie as if perfromance is somewhere in the ballpark of expectations of 8nm A76 its still going to be pretty awesome.
About only thing I don’t like about that board and the quibble is tiny is the onboard switches as jumpers would be my preference as like a normal mobo there is the option for wired switches.
Thnx for the info though.
The socket on the side is a micro-HDMI port, specifically micro-HDMI input - something everyone seems to have missed

Any interesting news on the development progress?
Wow thats over 30% than the 1st @anon39001862
Was there a problem with the memory before as guessing that has had the most effect but wow GPU is now 60% faster.
Is it stable though?
And will it play Netflix in 4k?
@mxcone17
Netflix doesn’t support open-source devices and only certify devices from billion dollar companies.
To support Netflix, the device will have to come with a locked bootloader, meaning no Linux OS’s or custom firmwares, no removable parts like emmc, pcie etc. and yearly license fees that run into the millions.
If LE is available later for Rock5, you should be able to stream 1080p Netflix.

Ready on Android?
What about in linux?
Btw first patch for Rk3588 have landed.
Now you can boot from emmc and kernel can load with just uart support now
Yeah https://lore.kernel.org/lkml/20220422170920.401914-1-sebastian.reichel@collabora.com/ and RK3588s so the process has started but HDMI input for linux prob going to be one of the last things done at a guesstimate.
Looks like collabora.com are on the job though which is a relief after seeing nothing for so long but guess they only got boards recently.
@anon39001862 Android 12 is pretty cool though and do you know if the Pixel6 offline ASR is going to be available or are they keeping that for just this release of pixel phones?
Also are you focusing on Android 12 Desktop Mode?
