04:12 <MasterR3C0RD> loki666: I think I'm probably good, at least for now. Should have a H616 board on the way soon, which should be enough for me to get to work on additional DRAM code. Thanks for the offer though!

10:24 <Soupborsh> @apritzel No.

10:26 <Soupborsh> There is U-Boot contains boot0 and Linux kernel sources for B288 but they are outdated and do not contain for example defconfigs and devicetrees for PB618. I am thinking that I should email Pocketbook to ask them to provide source code, I think they should provide it.

11:11 <apritzel> well, good luck with that ;-) And also be advised that getting mainline supported on an undocumented SoC is quite an endeavour (it's already quite tedious with a manual)

11:12 <apritzel> Soupborsh: do you have a pointer for the source code?

11:14 <Soupborsh> @apritzel https://github.com/pocketbook/kernel-b288

11:14 <Soupborsh> https://github.com/pocketbook/uboot_b288

11:14 <Soupborsh> Also I created a fork of kernel with added devicetree and defconfig extracted adn yylloc fix.

11:14 <Soupborsh> Dear PocketBook.... (full message at <https://matrix.org/oftc/media/v1/media/download/AR6_-wfbfa3TFRPEn5s0AEx3HuSCJKt_-zdnQ-HQfZZeiu4heYckfDCpmXNdfCUljmDQLszA-XixtdbrDOp3L_ZCeTXeE-0QAG1hdHJpeC5vcmcvY3l0Y2xpdGJVZkZ4S2VSWVVXdGJnQVlu>)

11:15 <Soupborsh> @apritzel Should I add more improvements to this letter

11:15 <Soupborsh> ?

11:15 <apritzel> it looks fine, but don't hold your breath on getting a positive reply

11:15 <gamiee> or any reply

11:17 <Soupborsh> At least I will try

11:17 <Soupborsh> https://github.com/pocketbook/kernel-b288 my fork

11:18 <Soupborsh> I did not succesfully compile u-boot yet.

11:20 <Soupborsh> <apritzel> "well, good luck with that..." <- Yes it is hard and does not give any significant benefits but it is fun and I am learning Linux, U-Boot and etc.

11:23 <Soupborsh> Do you know how do I fix usb_bulk_send() ERROR -7: Operation timed out error when trying to use read or spiflash-info.

16:41 <apritzel> Soupborsh: if you are doing it more for the experience: that's great, and you will learn a good deal of *real* Linux

16:41 <apritzel> just wanted to dampen your expectation of replacing the vendor firmware anytime soon ;-)

16:42 <apritzel> for instance I believe eInk is black magic, with secret recipes, I don't think we support anything "Allwinner eink" in mainline at all atm

16:59 <apritzel> so the problem in general is that this kernel of them is really rubbish

17:00 <apritzel> not only is the base very old (3.10), but of course the way they implement the drivers is very far from mainline

17:01 <apritzel> for instance the clock driver is completely different:

17:01 <apritzel> the only thing you can do is to extract the clock register information (which normally would be in the manual) from drivers/clk/sunxi/clk-sun8iw10.c, and then implement a proper modern clock driver based on that information
