By default, RK3399 boot order is SPIFlash, eMMC, and then SDCard ...

If you wish to boot the SDCard, you need to stop U-Boot with <spacebar> before it try to load kernel stuff, then you can do the following commands : 

mmc list
setenv devnum X          // where X is the SDCard number shown in previous list
run mmc_boot

Of course, if the eMMC has a old Android U-Boot, there is no warranty that the above commands will work.

In such case, the Raxda provided a eMMC-2-SDCard adaptor to be able to write to eMMC using normal USB-SDCard adaptor.

for whatever reason compiling ATF fails from time to time..

the sources with ATF were still there.. but int fails.. the merge looks like doing it for the wrong soc? someone has a clue?

 

Edit: if you build an image for the rockpro first.. it normally doesn't break.. 

'fixed' well it's not a nice fix but it does the job...

 

https://github.com/armbian/build/commit/6d9ab1c07c16ac990f620885dd9f0a6812f2a573

 

btw. it doesn't' like ISP1 as well.. means the kernel crashes quite soon.. :P

Hello all,

I have just got a all new Rockpi 4B.

I have installed the armbian image and xfce desktop.

I just have a problem, the wireless device is not available.

hwinfo --short gives the following result. I guess that broadcom is the wifi device but looks not to be recognized by the armbian image. Am I right ?

P.S. Also

Maybe their U-Boot check for presence of SDCard and give it a new priority, but the Rockchip SoC itself looks in this specific order is SPIFlash, eMMC, and then SDCard ...

So, if their U-Boot is erased/replaced by Armbian one, the order will be the one I've mentioned.

4.20.0 built myself 2 weeks ago ...

Obviously the problem comes from the Armbian image. I tested the Radxa Ubuntu server and with it the wifi is functional. Maybe I have to do the same as you have done, compile a kernel on my side. What type of platform do you specify Rockpro64 ?

I've looked at bash history of my RockPi, and ... : Oh ! I didn't remember, but I've used another firmware ...

Your mods works fine but only to connect to a network.

But the wifi is really unstable when used as hotspot.

Hope it will improve a bit in the future with new firmwares.

thanks very much - this makes me confident model A should be able to handle 2.02 as well

although stated differently at their page " Dual Cortex-72, frequency 1.8GHz ", cheers

well, that's just a device tree patching to run at 1.8 or 2.0GHz, cause RockPi is WIP don't expect that thermal behavior and stability at 2.0GHz is well tested at the moment.

Hi - I would be happy to test Rockpi4A with accompanying heatsink, but it seems a bit expensive to order in EU ( EUR48,29 ) instead China (USD39) - once I received these items I like to contribute testing its stability at 2.0GHz.

Anyway the heatsink looks decent to me and since it does not have to run 24/7 at 2.0GHz I am confident it can be "overclocked" to 2.0GHz for shorter periods, but I like to test that out for my use case ( ovpn with pi-hole ) .

Applied similar tweaks recently overlocking the nano pi neo2 lts (v1.1), updating armbianEnv.txt and cpufrequtils . 

The key to this is temperature, based on current findings neo2 board runs for little while ( 10-15 minutes ) on 1.3Ghz which makes roughly a 10 degrees CPU increase within 6 minutes,

but once it throttles back temp drops rapidly ( of course ) and as said I am condifent similar could be achieved with the Rockpi4...

I order regularly in China, the USA and in the EU, when comparing prices there are some things to consider.

Spoiler

 

1. In case of domestic orders, the dealer is obliged in the event of a warranty claim. How expensive and complex the return to China is, does not have to burden us. Furthermore, we sometimes have significantly higher shipping costs to China than the Chinese to Europe.

 

2 The call sales tax must be paid here with receipt. If DHL delivers, then they want to double the value of the tax for processing and loaning the amount! DHL delivers once, the drivers have no change and cannot settle cashless!  If you don't have the matching money, you have to go to the customs office! If the Deutsche Post delivers the parcel, then it is delivered directly to the nearest customs office and must be released there. This can be different in other EU countries. I live in a city of 500 K inhabitants, without a customs office and, as a cyclist with 6 hours time to pick up the parcel, I have to use public transport. If the invoice is not, easily accessible to customs, placed outside the packaging, customs cannot charge tax. Either we have to send a credible invoice, or the goods are estimated (extremely expensive!), or the goods are sent back. It is also important to note that shipping costs are subject to tax, which is quite expensive with Express Service.

Your mods works fine but only to connect to a network.

But the wifi is really unstable when used as hotspot.

Hope it will improve a bit in the future with new firmwares.

USB 3 isn't working properly, only usb2 via hub is reliable

neither wlan sticks nor other external devices like external storage can be used

The hostapd itself is cool
