04:35 <cyrozap> Hi, all, I'm trying to boot mainline U-Boot on an old Tronsmark MK908 II (RK3188-based TV box), but I can't seem to get quite the right combination of commands/flash offsets to work, and it's especially difficult because there's lots of outdated information floating around on how to boot this SoC.

04:38 <cyrozap> So far I've been able to build U-Boot image + SPL for the Raxda Rock (same SoC) and encoding that SPL file with `./tools/mkimage -n rk3188 -T rksd -d ./spl/u-boot-spl.bin` and flashing that to `bs=512 seek=64` gets the SoC out of mask ROM mode, but I can't figure out where I need to flash the main U-Boot image, and I don't know if I need to encrypt it with RC4 or not beforehand.

04:40 <cyrozap> Following the instructions in doc/README.rockchip hasn't worked (beyond getting the SoC out of mask ROM mode), and I'm not sure what to do now.

04:40 <cyrozap> I have UART access, so I've been using that for debugging.

04:41 <cyrozap> If anyone has any ideas and wants to help me boot this ancient technology, I'm all ears. :)

06:16 <Ke> since arm qemu team lives here, it may seem worth asking, whether people have been noticing rcu stalls in aarch64 vms

06:26 <ayaka> cyrozap, let me check the trm

06:28 <ayaka> cyrozap, I don't think the upstream SPI would need a cryptic u-boot image

06:30 <ayaka> cyrozap, that u-boot would be at 0x200 from the beginning of the storage

06:31 <cyrozap> ayaka: Oh, I forgot to mention I'm doing SD boot.

06:33 <cyrozap> There's also NAND on this board, but from what I've heard the open source NAND support doesn't work/isn't implemented, so I've just zeroed it out.

06:34 <Ke> I think spi would have needed -T rkspi or something anyway

06:56 <cyrozap> Oh, wait, I think I may have figured it out.

07:02 <cyrozap> Yeah, I think I can't get away with using a different board's DTS file :/

07:25 <cyrozap> I'm trying to hack the Raxda Rock DTS files to change the stdout UART, but I keep getting this error: `drivers/serial/serial_rockchip.c:35:33: error: 'struct dtd_rockchip_rk3188_uart' has no member named 'clock_frequency'`

07:26 <cyrozap> It's set to uart2 for the Rock, but I want to change it to a different UART because I think the MK908's uses a different one for its UART.

07:38 <cyrozap> Ok, it looks like I needed to add a clock-frequency property to the node, but I still don't get any stdout output.

10:08 <mmind00> cyrozap: https://github.com/mmind/u-boot-rockchip/commit/81458bde873d6cf588e082ccf556e818f46ad9df may help, but I'm not sure how outdated that is

10:09 <mmind00> cyrozap: but reading further down in your messages, it seems like you already got over that build-issue?

21:58 <stibitz> I've booted ubuntu on my rock960, but it's asking for a login. What is the default login to use?

22:07 <gab> stibitz: try "hello" or "please" ?
