07:02 <BusError> Are there restrictions on how big a file can be written with rockusb/rkdeveloptool? Here rkdeveloptool seems to write my whole ~913MB file to the device, but if I re-read it, it seems to have stopped more or less in the middle

07:02 <BusError> I tried writing with rockusb (command line tool, linux), same problem

07:03 <BusError> I use rk356x_spl_loader_ddr1056_v1.06.110.bin -- which I fished from the internet, as it's not in rkbin or anywhere else 'official' it seems

12:19 <naoki> BusError: I don't think there are any such restrictions, but I'm not familiar with them.

12:33 <naoki> By the way, I'm wondering if those tools support these operations... https://github.com/linux-rockchip/rkflashtool/commit/6da95a860e856e559310a6d96830eb687c23a132 https://github.com/linux-rockchip/rkflashtool/commit/3c3bf5f19aeceb346c1d1983625e11ebf633334f

12:35 <naoki> I don't feel like doing it, but this needs to be fixed to support recent(aarch64) SoCs. https://github.com/linux-rockchip/rkflashtool/blob/master/rkflashtool.c#L54

12:43 <naoki> Ah, U-Boot on recent SoCs doesn't use BACK_TO_BROM, so rkflashtool L/M/B might not work... (I need to check U-Boot's rockusb implementation)

12:51 <naoki> It seems that mainline U-Boot only supports a limited number of operations. https://source.denx.de/u-boot/u-boot/-/blob/master/drivers/usb/gadget/f_rockusb.c#L783

13:13 <naoki> hmm

13:14 <naoki> ./rkflashtool l < ../rkbin/bin/rk35/rk3588_ddr_lp4_2112MHz_lp5_2400MHz_v1.18.bin

13:14 <naoki> ./rkflashtool L < ../rkbin/bin/rk35/rk3588_usbplug_v1.11.bin

13:14 <naoki> works

13:21 <naoki> ./rkflashtool l < ../rkbin/bin/rk35/rk3588_ddr_lp4_2112MHz_lp5_2400MHz_v1.18.bin

13:21 <naoki> /rkflashtool L < ../u-boot/spl/u-boot-spl-dtb.bin

13:21 <naoki> U-Boot SPL 2025.01-rc5-00015-g20f6e80312c7 (Dec 30 2024 - 13:17:56 +0000)

13:21 <naoki> Trying to boot from MMC2

13:21 <naoki> (snip)

13:21 <naoki> SPL: failed to boot from all boot devices

13:21 <naoki> Interesting :)

13:59 <naoki> Oh, bulk transfer endpoint is changed after exiting MASKROM mode on RK3588

14:00 <naoki> rkflashtool needs to be fixed ;)

14:19 <naoki> ./rkflashtool m 0 0x10 | hexdump -C

14:19 <naoki> interesting :)

14:30 <naoki> memory read/write is working, but exec (rkflashtool B) is not working

21:23 <naoki> board_spl_was_booted_from: failed to resolve brom_bootdevice_id a

21:23 <naoki> BROM_BOOTSOURCE_USB = 10,

21:28 <naoki> How to use common/spl/spl_ram.c...?

22:22 <naoki> hmm

22:23 <naoki> rkflashtool l < tpl.bin

22:23 <naoki> rlflashtool L < spl.bin

22:23 <naoki> rkflashtool L < u-boot-rockchip.bin

22:23 <naoki> works but

22:23 <naoki> doesn't work
