well I guess you have to recompile the module itself because it could be compiled for other kernel
just to let you know if you do apt-get update then you can install headers for your kernel and compile if you have sources for that dongle , of course !!
yes the project is going on , the problems as already said in this post are:
1) the ddr aren't egual, each board needs its own loader, actually ONE solution is using original rkxxxxxxxx.img loader
2) some board using emmc, some other using nand. It is necessary compile kernel and adjust resources ( dtb) to use or not a driver that is incompatible in case of emmc or nand ( must use one OR other )
3) depending on dimension of firmware and of board is necessary adjust the mtdparts in parameters.txt
4) not decent graphical hardware acceleration avaible, we can use those boards as ftp, dlna servers, voip but not yet possible use them as players for videos
This is the reason isn't yet been released a guide, a team is making all efforts to have ONE quite satisfull guide to at least give guidelines
I can say that original loader from android for that particular board + original uboot from android for that particular board + original trust from PARTICULAR android ( trust_with_ta_ga4fd2d1.img ) are actually giving a quite universal way to boot the board.
then is COMPULSORY adjust parameters.txt to give the right location of rootfs and is possible use kernel-4.4.138-respeaker-r0 and resources-rk3229-respeaker-v2.dtb from respeaker project to at least give life to board .
and follow the uart log to have an idea of what is needed to change to give right path to kernel for finding rootfs
I suppose will quite never exist an UNIVERSAL image to flash will be alway necessary tweak on every single board so uart connection are needed
Now some questions:
1) which android rom your board uses?
2) have you access to uart logs?
Hello all good people
The loader for booting from internal storage is the same one included in original stock ROM
Universal loader for booting from SD (Â not only Linux but any os) doesn't exist and is not enough say I have 1 giga/8giga
I completly agree, tried different loaders, u-boot ... same result , when I'll have some spare time will try to take the logs. maybe the bord have some HW jumpers that indicates how to boot or maybe SD is attached to different pins for booting who knows... maybe logs will show... Bought them only for cheap linux device hope will succed.
Hi,
Could boot linux, what I understood that board shouldn't have any loader, then it will normaly boot with sdcard, and also loader and and u-boot from respeaker are specific to that board(or type of the boards) otherwise you need to compile them from sources.
No need to ground simply erase internal flash(can be dome with Android rk tools) and it will boot from SD. The first log with GTP is from Android 9 it is interesating, second log is using ondoard loader that triest to boot SD but it's waiting for different partitioning...I think everything depends on loader on Optee_os part.
xwx
You so right that can't imagine.
Android 9 is not booting on those boards ( yet) but partitioning you can change in maskrom mode.
I am not home unyun Monday but I will put here some got partitions and some ideas for booti g from sd
