Not booting from SD card

[aaronw2]

I am attempting to upgrade U-Boot on my board but there is no output after it starts. I did change v2024.01 instead of the release candidate.

Note that I am quite familiar with U-Boot since I am a developer who works on U-Boot and ATF for a different ARM SoC vendor.

My toolchain is also gcc-14, if that makes any difference.

I have noticed problems even with gcc-13, so I now build with gcc-12. Give gcc-12 a try.

Do the known working images work for you? https://github.com/inindev/uboot-rockchip/releases/tag/v2024.07-rc4

Thanks,

I'll try it with GCC. I work on Marvell SoCs and we use gcc-12 for that, though my distro supports gcc-14 for the AARCH64 toolchain.

Note that with the older release I was able to enable HS400ES mode for eMMC and that appears to work. For many years I maintained the Cavium MIPS U-Boot and I now do some work on the OcteonTX U-Boot.

I can get U-Boot compiled with gcc-14 working if I load it from the shipped U- Boot to 0xa00000 and jump to it. I will try the new binaries, though.

I am unsure there is an issue with gcc-13 (the one I had trouble with), but I did see it sporadically hang on the boot prompt rather than default boot (I would need to select an option from the menu). I just assumed there was a new optimization flag or setting that u-boot has not accounted for at this point. Let me know if gcc-12 makes a difference for you.

I will when I get a chance. I'm in the process of migrating my main computer to new hardware.

I am trying the official release and while it boots to a prompt it looks like USB is not working. usb scan hangs.

=> usb start starting USB... Bus @.: USB EHCI 1.00 Bus @.:

I am also able to build my own U-Boot but I see the same behavior.

then I lose control of my usb serial console...
