00:27 <apritzel> eliasbakken: very nice! Any surprising things on the way? Clock gates? power domains?

11:25 <eliasbakken> aprtizel: Not for me, but things might have gotten set up by that TF-A that shipped with the distro that came with the Orange Pi 4a. There was already an SCP binary loaded, so I just asserted reset, wrote the exception vectors, loaded my own code and deasserted reset.

11:34 <apritzel> ah, nice! We got basic "organic" support running now, with SPL incl. DRAM init, some early TF-A port, and U-Boot proper working now, ready to launch the proposed patches for the kernel

11:35 <apritzel> eliasbakken: do you have an actual OPi-4A, or are you just using their firmware drops?

11:41 <eliasbakken> I have the hardware. Where are you posting your work? Would be interesting to follow along.

11:56 <apritzel> eliasbakken: ah, you seem to be the first one in here admitting having the OrangePi. I was always curious about that one, do you have the schematics?

11:57 <apritzel> couldn't find them on OrangePi's website, just an empty folder

11:57 <apritzel> 4 USB, an 2280 M.2 plus exposed ADC pins sound interesting, but I busted my board budget already ;-)

11:58 <apritzel> eliasbakken: Linux is here: https://github.com/apritzel/linux/commits/a523-v2-WIP/. I posted a series in November, and preparing a v2 to be posted in the next days

11:58 <eliasbakken> No, unfortunately they have not published the schematics, only an empty folder :| It looks like a 4 layer PCB though based on the 45 degrees rotation on of the SoC.

12:00 <apritzel> U-Boot is here: https://github.com/apritzel/u-boot/commits/a523/, and jernej has a TF-A branch: https://github.com/jernejsk/arm-trusted-firmware/commits/a523/

12:04 <eliasbakken> Oh wow, looks like a lot is going on. What hardware do you have?

12:04 <apritzel> eliasbakken: can you maybe poke OrangePi? Using some corporate email footer, for effects? ;-) It would be extremely useful for creating the DT

12:05 <apritzel> jernej: do you have any contacts into OrangePi?

12:07 <eliasbakken> I'll see what I can do.

12:10 <eliasbakken> Ok, email sent. Still new years celebrations for while longer though.

12:13 <apritzel> yeah, another week I think

21:21 <BroderTuck> Seems we have confirmation that there really is an arisc on the A523 family SoCs...
