Hi! I'm playing with S4 mini, and I can get to init/main.c:
writel(0xffffff, (void *) 0x88100030); print_kernel_cmdline(saved_command_line); I'm not sure I have right .config or pass right parameters to mkbootimg. I started from commit b51f999a8ab27982c2b5ea07f963cd226058ac04 (origin/msm8227-6.19, origin/HEAD) Author: user0-07161 <[email protected]> Date: Sun Dec 21 12:01:52 2025 +0100 fix wifi for loganre and break wifi for others commit 661c321a9c4bdf9ae41fc084e1f1bdb5bf338622 Author: user0-07161 <[email protected]> Date: Sat Dec 20 22:02:23 2025 +0100 make the charger driver compile again commit 48f5ca0471184a7bcbe4beffb29180f7da076b91 Author: user0-07161 <[email protected]> Date: Sat Dec 20 20:58:55 2025 +0100 replace l22 value with the one from downstream commit 94fd592c86d23706c60289147c8b21f73f3c7a18 Author: Julian Rother <[email protected]> Date: Fri Oct 24 23:29:06 2025 +0200 Initial dts for Samsung Galaxy S4 Mini International LTE I got config by cp ./arch/arm/configs/qcom_msm8227_defconfig .config and I'm attempting to boot from lk2nd make -j 25 ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- oldconfig zImage dtbs cat arch/arm/boot/zImage arch/arm/boot/dts/qcom/qcom-msm8930-samsung-serranolte.dtb > kernel.bin mkbootimg -o boot.img --pagesize 4096 --base 0x80200000 --kernel_offset 0x00008000 --ramdisk_offset 0x02000000 --second_offset 0x00f00000 --tags_offset 0x00000100 --kernel kernel.bin --ramdisk ../rootfs.cpio.gz --cmdline "console=ttyMSM0,115200 earlycon" fastboot boot boot.img Would someone be willing to supply known-good .config and mkbootimg parameters? I noticed lk2nd puts framebuffer at different address, so I did: +++ b/arch/arm/boot/dts/qcom/qcom-msm8930-samsung-serranolte.dts @@ -27,7 +27,7 @@ chosen { framebuffer0: framebuffer@88300000 { compatible = "simple-framebuffer"; - reg = <0x88300000 0x300000>; + reg = <0x88100000 0x300000>; ...but I get hang with or without that patch. I also tried origin/msm8227-6.15 , but same results. I attempted to debug things by enabling early access to framebuffer and then drawing dots. That works, but I was told there's "earlyfb" patch that would make that easier. I could not find it, so pointer would be welcome. Thanks and best regards, Pavel -- I don't work for Nazis and criminals, and neither should you. Boycott Putin, Trump, Netanyahu and Musk!
