I did build with those flags yes, I will do it again and post the output but it did not work it seems .. have you tried building from scratch?

is someone going to fix the build system so that these boards can be used?

that directory does not exist
under vendor the only dir called wifi is vendor/rockchip/common/wifi and they are not there

there is no lib under vendor

strange thank you attached again

I would also note during the build, if i ran ./build-nanopc-t4.sh with -W option (i belueve it was) ,.. it said it would generate outptut .ko files in a certain directory but it did not generate anything there ... the build all option -F -M is suggested which is what i did and that did not generate ...

attached log file from logcat

I will get the log tonight .. note that this is using the latest 8.1 branch from friendlyarm with no modifications on the nanopi-m4v2 board ... the hardware did work with the android on the eMMC module so something seems wrong with the android 8.1 branch ... i will get the log and post today

i will check and post .. the toggle switch does not slide to the on position but there was no visible error in Android .. i will check the debug output and post

lots of errors in build not sure which are important, but wifi does not work .. any ideas?

Nanopi M4V2 board, android 8.1 build (no changes made)

serial output attached

same issue .. i finally got the android 8 build working and flashed, but now the wifi does not work .. i know the hardware works becausei tried it on the image that came with the eMMC module ... but after i flashed a newly built android 8 system (unmodified), and updating the Nanopi M4V2 board, wifi...

I believe this time it worked. I had to remake the flasher SD card, rebuild android eight, figure out the boot sequence button press,and had no issues with the flasher program ... Android booted just fine although I didn’t do anything custom so I’ll have to try that next but it looks promising thank...

The current situation is that I am now able to run the flasher program (it seems you have to hold the power button for a couple seconds), but flashing only works with the vanilla images ... when i make a new android build that is successful, and copy all the files to the flasher sd card, that does n...

I think I may have figured it out. It seems like the speed of the SD card was the problem. I put in another card with a faster speed and it seemed to work ... i did see the flasher program for the first time ... trying now

boot or recovery image sha mismatch!
Unable to boot:boot
try to start recovery
'recovery' does not seem to be a partition nor an address
Unable to boot:recovery
try to start backup
'backup' does not seem to be a partition nor an address
Unable to boot:backup
try to start rockusb

it stays on that screen forever

build is complete .. followed instructions for android 8 ... copied all files to android 8 folder on sdcard flasher ... same thing .. does not boot, no green lights .. i also used a brand new eMMc i got today

that is the one .. the script to run there is build-nanopc-t4.sh per the info on the wiki .. is this correct? i meant to say t4

build is almost done trying now

Recovery and backup partitions seem to be missing as well ... i burned the card fresh with the android 8 flasher image .. then copied all files from rockdev/Image-xxx/ into the android8 folder on the se card ... again, this is for the M4V2 board but the repo was referencing the nanopc-T2 board ... i...

Below is the debug output .. it seems there are some sha mismatch errors .. what does that mean? ---- U-Boot 2014.10-RK3399-06 (Aug 06 2019 - 19:08:49) CPU: rk3399 cpu version = 0 CPU's clock information: aplll = 816000000HZ apllb = 24000000HZ gpll = 800000000HZ aclk_periph_h = 133333333HZ, hclk_per...

Thank you i am going to try again with an android 8 build

That’s great news, if there’s nothing I could have done to mess up the MMC partitions or anything after burning an image there erroneously then i will try it again this time with the android 8 build i just created and the android8 flasher img on the sdcard

I have an eMMC module .. instead of preparing an SD card and trying to get the eflasher program running, can't i just flash the module directly? it comes with an sdcard adapter and i am able to write to it .. what files should i write to the eMMc module for android 7 and also for androi 8 to write d...

ok so i guess i was seeing the preinstalled android working .not my custom build .. thank you, i had some questions in another post

ok, i found the images under rockdev in the custom build directories .. after flashing the rk3399-eflasher-android7-20200324.img file to the sdcard, then inserting the sdcard again, i see the rootfs and Friendlyarm partitions .. this sounds right so far ... then i copied all the files from the rockd...

thank you i will try that .. i am using android 7 but hopefully it is similar

Thank you .. the custom build went perfectly .. now i want to make the sd card flasher to write to the eMMC .. from this page: https://github.com/friendlyarm/sd-fuse_rk3399. it is not very clear .... in one place it says for android you have to make an eflasher sd card ... but then the rest does not...

Hey guys I wanted first say great job with setting up tools that actually work out of the box ... I have the NanoPI M4V2 board, and have been trying to get Android 7 running ... i used the docker system to get setup, which worked perfectly with no issues on ubuntu 18 ... great .... then i tried the ...

Hello, I was able to follow your wiki on how to build android nougat for NanoPi M4V2, but i am having trouble figuring out the steps to prepare the SD card ... which script do i run to create the sd card that will boot Android 7 for this board? Is there a clear list of the files needed, and how to m...
