04:31 <naoki> I remembered there is boot_merger source https://github.com/rockchip-linux/u-boot/tree/next-dev/tools/rockchip

04:31 <naoki> but it might be old

05:27 <naoki> Kwiboo: your ramboot doesn't work with ROCK 5B 16GB RAM https://gist.github.com/RadxaNaoki/0d6be50943f79cb0b62b2ef075e3a938

09:43 <Kwiboo> naoki: yes currently there is issues with rk3588 16+ GB DRAM, the RK atags in DRAM created by TPL is overwritten when the 472 image is loaded into DRAM :/, temp workaround: use mem=16062M or similar in linux cmdline to limit mem usage to below the 0x3fc000000 address, where a 0x500000 hole needs to be carved out

09:44 <Kwiboo> https://gist.github.com/Kwiboo/1c020d37e3adbc9d0d79dc003d921977 has a dump collection of different RK atags for rk3588 and different RAM sizes

09:47 <naoki> Kwiboo: So I tried DFU, but it hangs in the middle of kernel booting...

09:48 <naoki> I'm trying DFU on other devices now...

09:52 <Kwiboo> hehe, the dwc3 code in u-boot is not in very good state and was long time ago it was fully syned to linux, it should really be synced to latest linux, but no one has been willing to take on such demanding task

09:59 <Kwiboo> naoki: https://gitlab.collabora.com/hardware-enablement/rockchip-3588/u-boot/-/commits/2024.01-rk3588 have some dwc3 commits that seemed to be needed in u-boot to get DFU working for rk3588

10:00 <Kwiboo> they was rejected by upstream u-boot usb maintainer because a full sync should/needs to be done, not just a partial sync

10:01 <naoki> well, DFU in SPL is working on ROCK 5B, U-Boot can be loaded and run

10:02 <naoki> Loading kernel etc from NVMe is also working, but kernel hangs

10:06 <naoki> DFU in SPL on ROCK 3A: both U-Boot and kernel work fine

10:09 <naoki> By the way, your ramboot and my DFU in SPL can coexist.

10:09 <naoki> U-Boot SPL 2025.01-rc6-00005-g4aff630b05d6-dirty (Jan 02 2025 - 10:00:38 +0000)

10:09 <naoki> Trying to boot from RAM

10:09 <naoki> Trying to boot from DFU

10:09 <naoki> Ctrl+C to exit ...

10:09 <naoki> ##DOWNLOAD ... OK

10:09 <naoki> just sending u-boot-spl-dtb.bin instead of472.bin

10:40 <naoki> Kwiboo: https://github.com/RadxaNaoki/u-boot/commits/rk3xxx-ramboot/

10:40 <naoki> My work so far

10:41 <naoki> I already tried your ramboot on ROCK Pi E(RK3328) and ROCK Pi S(RK3308). it works fine :)

10:56 <Kwiboo> naoki: cool and thanks, will try to send it out as an RFC in a few days

13:38 <Daanct12> greets all, i'm currently working on vop2 support for u-boot :)

13:38 <Daanct12> currently i got it to work nicely, but there's still a little noise on the display

13:56 <naoki> hmm, DFU in SPL with dwc2(RK3308/RK3328) is not working...

14:06 <naoki> ah, it works :)
