Hi guys,

 

I have a BPI-M3, and wanted to roll my own build, given the current dissatisfaction with the builds provided by Sinovoip themselves.

 

In any case, I have tested this locally, and it builds a bootable sd card, which works on UART only.

 

It doesn't have working ethernet or WiFi, but at least you can interact with it over UART.

 

Please feel free to review and comment on the script, and let me know if there are any issues running in your environment (ie, prerequisites that I have already, and make an invalid assumption that it is present).

 

As per the comment inside the script, it will wipe the sdcard specified, and repartition with one partition which takes all but the first 2Mb (reserved for u-boot).

 

Cheers,

 

Damien

It doesn't have working ethernet or WiFi

 

You should also keep in mind that it has no thermal protection. This is an issue for us preventing mainline kernel OS images for H3 boards at the moment where the chance to damage the SoC is not that huge (you would've to run pretty heavy workloads to damage H3). On A83T at the current state it depends on CPU clockspeed set in u-boot what will happen. Please compare with my measurements with legacy kernel: http://linux-sunxi.org/Banana_Pi_M3#Sudden_shut_offs_.2F_maximum_consumption_.2F_cooling_vs._consumption

 

In other words: Depending on maximum clockspeed allowed you might be able to easily damage A83T if/when SMP is working.

 

In my eyes BPi M3 is one of the most uninteresting boards we've seen so far (see link above) and especially its user base is strange (look through bananapi forums). So I'm rather happy to not support the board and its users now. Might change if full mainline kernel support is ready sometimes in the future. But I see almost no reasonable use case where M3 would be able to shine (high CPU performance only with liquid cooling, very low I/O bandwidth, see here also).

 

But thx for sharing your script anyway. Might be of help for people trying out mainline u-boot/kernel now on the board to do at least something useful with it.

Hi,

 

Did your linux tree get switched to the other branch ?   Did you git clone into ./linux before the process ran?

 

In the linux directory, what does "git branch" show you ?

 

Cheers,

 

Damien

I found some issues with a blank slate, am testing some changes and will post a new version shortly

This semi working search is annoying me too. :angry: I will try with Sphinx search server - I hope this will help.

 

BTW: I also installed Slackware but full setup with a bag of floppies :)

Hi guys,

 

Updated with some bug fixes in the script, and swapped the u-boot branch to https://github.com/wens/u-boot-sunxi.git, branch a80-pmic which brings up the PHY properly.

 

You should change the .au. to the closest debian mirror to you, otherwise transferring all of the packages from Australia is probably not what you want to do :)

 

Cheers,

 

Damien
