<exkcmoeAdmin[m]> > Gotta love when the Amlogic OpenLinux doesn't have any sources whatsoever.

<exkcmoeAdmin[m]> it used to has a way to get file for them without asking them to add your ssh key to their server via emaile
<exkcmoeAdmin[m]> (yes you can git clone them after they has added your ssh key to their server)
<exkcmoeAdmin[m]> (however it might a pain in the ass
<exkcmoeAdmin[m]> to ask them to add your ssh key via email)

<f_> chewitt: Did you build this??

<f_> If so, can you please share the sources (if you legally can, of course)?

<f_> Anyone?

<exkcmoeAdmin[m]> ram stuff i guess
<exkcmoeAdmin[m]> I mean stuff thzat related to ram
<exkcmoeAdmin[m]> Also
<exkcmoeAdmin[m]> nothing
<f_> ...
<f_> Of course it does stuff related to RAM timing, but *what*?
GNUtoo has quit [Ping timeout: 240 seconds]
<exkcmoeAdmin[m]> ram timings
<exkcmoeAdmin[m]> as i remeber

<exkcmoeAdmin[m]> chewitt has said what is for
<exkcmoeAdmin[m]> as i remeber
<f_> Where??
<exkcmoeAdmin[m]> here
<f_> ...
<f_> Oh so repk_ ported TF-A BL31 to the S905?
<exkcmoeAdmin[m]> maybe ?

<narmstrong> It fits the acs binary into bl2
<narmstrong> ACS contains ddr and clocks settings
<f_> Sure. Do we know how acs.bin works?
<f_> Got a datasheet for the RAM chips used in my set-top box, and it seems to have all core timing docmented.
<f_> *documented :^)
<f_> Now......where do I have to define all those to then build a working acs.bin file?
<f_> Would be easier if WeTek publicly released the U-Boot sources lol
<f_> Although my set-top box definitely isn't a WeTek Play2, it's still quite similar (it's a KII Pro)
<f_> Well..at the very least they share the same RAM chips.
<f_> Meanwhile I'm digging inside logs from freenode =)
<f_> And I see....
<f_> <damex> and bl30 is closed source too?
<f_> <repk> damex: yes but it is likely based on https://github.com/ARM-software/SCP-firmware. <...>

<f_> Uh. AntonioND made the TF-A port.
<f_> narmstrong: For now I think I'll give up on BL2 and instead try to focus on BL30(1).
<f_> narmstrong: If I understood correctly, blx_fix.sh is used (in amlogic-boot-fip.git) for bundling BL301 to BL30, right?
