07:55 <mmind00> Ermine: rk3288 does have full dram init in uboot and the kernel uses the "old" in-kernel smp bringup with being arm32, so that _should_ just work

09:20 <Ermine> qschulz: currently we use stuff from rkbin to make idbloader and stuff as per rockchip wiki

09:23 <qschulz> Ermine: don't read rockchip wiki for upstream stuff :)

09:24 <Ermine> Okay

09:24 <qschulz> idbloader from rkbin is typically only useful if you don't have an open-source DRAM initialization available in U-Boot

09:25 <qschulz> it's essentially U-Boot TPL/SPL

09:25 <qschulz> but if you have open-source DRAM init, then you don't need it

09:25 <Ermine> Well, if I just can throw away those blob I'll be just happy

09:25 <qschulz> you should be able to

09:25 <qschulz> https://docs.u-boot.org/en/latest/board/rockchip/rockchip.html

09:25 <qschulz> those still may be outdated but they have worked at some point with upstream U-Boot on RK3288

09:26 <qschulz> what you want to flash on your eMMC/SD is u-boot-rockchip.bin, at the same offset you would flash idbloader

09:26 <qschulz> typically offset 32KiB (so block number 64 if you use rkdeveloptool for example)

09:27 <Ermine> Okay, will figure out my dts issue first then

09:28 <qschulz> what's the error with your DTS?

09:29 <qschulz> is it still the same DTS as last attempt on #u-boot yesterday?

09:36 <Ermine> qschulz: yes

09:37 ldevulder has quit [Ping timeout: 255 seconds]

09:38 <qschulz> Ermine: can we have the build logs?

09:39 <qschulz> Ermine: first, you should start by including rk3288.dtsi in your rk3288-lango.dts

09:40 <qschulz> then in arch/arm/dts/rk3288-lango-u-boot.dtsi you can include rk3288-u-boot.dtsi

09:53 <Ermine> qschulz: logs with rk3288.dtsi included: https://0x0.st/Kz1X.log

09:55 <Ermine> IIUC this happens because I haven't specified some stuff in my dts

09:56 <qschulz> Ermine: look at the &dmc entry in rk3288-evb-u-boot.dtsi

09:56 <qschulz> you're probably missing something like that

09:57 <qschulz> now how you come up with those values.... I don't know

09:58 <Ermine> i have downstream dts extracted from android which is originally shipped with this board

09:58 <qschulz> ah, maybe it does have those values then!

10:11 <Ermine> Should we continue in #u-boot ?

10:13 <qschulz> up to you, both are fine

10:17 <Ermine> okay, is there documentation on rk3288-dmc binding?

15:09 nea999 has quit [Ping timeout: 245 seconds]

15:10 <Ermine> that downstream dts doesn't have anything about sdram. shoot.

15:14 <Ermine> can it be dangerous to try timings from other boards?

15:16 raster has joined #linux-rockchip

15:17 * Ermine has to study electricity

15:20 ldevulder has joined #linux-rockchip

15:21 <qschulz> no clue. I would say worst case scenario the DRAM isn't fully working and rebooting should get rid of it, but I have no knowledge in that

15:24 <beeble> wrong timings will not damage it

15:35 <Ermine> That's great
