  1. Please write instructions on how you make the mainline u-boot. I collect according to thisinstructions and see: U-Boot TPL 2022.07-rc6-00006-g2d2c61ff04 (Jul 23 2022 - 00:45:42) DDR3, 333MHz BW=32 Col=11 Bk=8 CS0 Row=16 CS=1 Die BW=16 Size=4096MB Trying to boot from BOOTROM Returning to boot ROM... <debug_uart> <debug_uart> U-Boot SPL 2022.07-rc6-00006-g2d2c61ff04 (Jul 23 2022 - 00:45:42 +0300) Trying to boot from MMC2 mmc_load_image_raw_sector: mmc block read error Trying to boot from MMC1 mmc_load_image_raw_sector: mmc block read error SPL: failed to boot from all boot devices ### ERROR ### Please RESET the board ###
  2. No, I set the bitrate to the correct one. It helped me to close contact TP50265 to GND during power-on.
  3. Hello! I wrote the wrong bootloader to the emms, now the download does not happen with either emmc or micro-sd. U-Boot TPL 2020.10-00676-g9885313b9a (Oct 13 2020 - 06:24:16) sdram_init: LPDDR3 - 933MHz failed! rk3399_dmc_init DRAM init failed -22 Missing DTB Now I can't use the board in any way, how can I clear the emmc memory?
  4. Can you show the source repository for the current kernel branch?
  5. Device is Orange Pi4 For example, so that it displays: * Mounting debug filesystem ... [ ok ] * Mounting config filesystem ... [ ok ] * Mounting cgroup filesystem ... [ ok ] * Remounting devtmpfs on /dev ... [ ok ] * Mounting /dev/mqueue ... [ ok ] * Mounting /dev/shm ... [ ok ] * Creating list of required static device nodes for the current kernel ... [ ok ] * Starting udev ... [ ok ] * Generating a rule to create a /dev/root symlink ... [ ok ] * Populating /dev with existing devices through uevents ... Kernel is 5.4.23-rockchip64
  6. Where can I find a link to the source git for What source code are the 5.4.23-rockchip64 kernels from?
  7. The script does not work for me: # ./compile.sh ./compile.sh: line 77: systemd-detect-virt: command not found [ o.k. ] Create example config file using template [ config-default.conf ] [ o.k. ] Using config file [ /usr/src/build/userpatches/config-example.conf ] /usr/src/build/lib/main.sh: line 136: dialog: command not found [ error ] ERROR in function source [ main.sh:138 ] [ error ] No option selected [ o.k. ] Process terminated Need another option, manual configuration u-boot.
  8. But I would like to learn how to configure u-boot for any supported kernel.
  9. Can you talk more about the build script and docker? I built Gentoo on an Armbian kernel and I want to rebuild the kernel on it, I have problems with sound.
  10. I work from a gentoo distribution, so I can not use the armbian script.
  11. The symbolic link to the image has changed, the kernel does not load: Applying kernel provided DT fixup script (sun8i-h3-fixup.scr) ## Executing script at 44000000 SCRIPT FAILED: continuing... Is it not enough to change one symbolic link to load another kernel?
  12. Hello dear developers and visitors to the forum. I have compiled my core for the opi3 board, but I do not know what to do to test my core. There is little information on the u-boot bootloader and I can’t configure it on my kernel, if I replace the vmlinuz-5.4.7-sunxi64 file, the board does not start, u-boot reports that there is no kernel image. I turn to professionals, please teach me how to work with U-Boot.
