Hi Patrice, Alain, Could you help to take a look at this patchset, thanks. This series is the rebase to the newest kernel commit: 88b06399c9c766c283e070b022b5ceafa4f63f19 according to the request from: https://lore.kernel.org/lkml/ff2bc09d-1a17-50d4-d3ee-16fd3a86d7f1@foss.st.com/ The clk bug affects the kernel bootup on stm32f469-disco board in case display config(CONFIG_DRM_STM, CONFIG_DRM_STM_DSI, DRM_PANEL_ORISETECH_OTM8009A) enabled. If you want to test clk patch on stm32f429-disco board, the panel-ilitek-ili9341.c can be used for that purpose (CONFIG_DRM_STM, DRM_PANEL_ILITEK_ILI9341) i2c driver patch intent to fix the touch panel driver get data through i2c bus timeout issue. Best regards.

Could you post all the logs from u-boot startup to kernel log end. If possible, you can try my suggestion. - tar -jxf stm32_rootfs.tar.bz2 - add stm32_rootfs to your kernel config( enable initramfs) - make O=YOUR_KERNEL_OUT zImage dtbs LOADADDR=0x90008000 - create itb file (combine dtb and kernel, initramfs) by mkimage ./mkimage -f stm32.its stm32.itb (before above command, make sure you correct stm32.its adapt to your env) This process will make u-boot to load the kernel more simple. Thanks. Best Regards.

Yes, your log is ok. I tried to follow your way(dtb + uImage) to figure out why your kernel was hanging there, but no luck. You can find my log from [1] . (since my uImage is bigger than yours, i change the loadaddr to 0x90300000, 0x90306000) but there are some points we can check: - kernel config, you can find my config in [2], could you share yours to me as well, i can based on your configs to test. - uImage size (yours 1593664 bytes is quite smaller than mine, 2072864 bytes the difference based on kernel config and rootfs size) - cross tool chain (upload my toolchain to google drive [3]) - could you add initcall_debug to your bootargs, to see more log at kernel startup [1] kernel log based on dtb + uImage https://drive.google.com/file/d/1wnA5b3B_6MIb4PWZXn-3DlBbxpi41uSA/view?usp=sharing [2] kernel config https://drive.google.com/file/d/1oOJt3NRYor3-Uzjpzrujv3uvWguxYQQp/view?usp=sharing [3] arm-none-eabi- toolchain https://drive.google.com/file/d/1Aq0sF2Gi4y4qaDPnM2S0xCOowFSLZYJm/view?usp=sharing Best Regards Dillon > > > > > >> U-Boot > > >> U-Boot > > >> U-Boot > setenv loadaddr 0x90400000 > >> U-Boot > loady > >> ## Ready for binary (ymodem) download to 0x90400000 at 115200 bps... > >> CxyzModem - CRC mode, 156(SOH)/0(STX)/0(CAN) packets, 7 retries > >> ## Total Size = 0x00004cad = 19629 Bytes > >> U-Boot > setenv loadaddr 0x90406000 > >> U-Boot > loady > >> ## Ready for binary (ymodem) download to 0x90406000 at 115200 bps... > >> C- CRC mode, 12453(SOH)/0(STX)/0(CAN) packets, 4 retries > >> ## Total Size = 0x00185140 = 1593664 Bytes > >> U-Boot > bootm 0x90406000 - 0x90400000 > >> ## Booting kernel from Legacy Image at 90406000 ... > >> Image Name: Linux-5.13.0-rc1-00082-g9dbbd5cb > >> Image Type: ARM Linux Kernel Image (uncompressed) > >> Data Size: 1593600 Bytes = 1.5 MiB > >> Load Address: 90008000 > >> Entry Point: 90008000 > >> Verifying Checksum ...

Then i used an another rootfs (attached rootfs_mcu.cpio file) but unfortunately, during the rootfs init, some memory allocation are done and failed due to low RAM available on this board. The issue seems linked to the rootfs...but i got no clue on what is going wrong with your rootfs ?
