Seems a typo introduced with the defconfig\n (AM57xx always used ttyS2 as kernel console).\n\n[1] https://source.denx.de/u-boot/u-boot/-/commit/649f4a7d3ca753991c27c9c159a0aacc9954d96f\n\nSigned-off-by: Romain Naour \n---\n .checkpackageignore | 1 -\n board/ti/am574x-idk/extlinux.conf | 2 +-\n board/ti/am574x-idk/genimage.cfg | 5 +++--\n board/ti/am574x-idk/patches/linux/linux.hash | 2 ++\n board/ti/am574x-idk/patches/uboot/uboot.hash | 2 ++\n configs/am574x_idk_defconfig | 12 +++++++++---\n 6 files changed, 17 insertions(+), 7 deletions(-)\n create mode 100644 board/ti/am574x-idk/patches/linux/linux.hash\n create mode 100644 board/ti/am574x-idk/patches/uboot/uboot.hash","diff":"diff --git a/.checkpackageignore b/.checkpackageignore\nindex 6599435b62..a708b081e7 100644\n--- a/.checkpackageignore\n+++ b/.checkpackageignore\n@@ -70,7 +70,6 @@ boot/syslinux/0013-Fix-build-with-gnu-efi-version-3.0.9.patch lib_patch.Upstream\n boot/syslinux/0014-Fix-build-with-binutils-note-gnu-property-section.patch lib_patch.Upstream\n boot/syslinux/0016-Workaround-multiple-definition-of-symbol-errors.patch lib_patch.Upstream\n boot/syslinux/0017-Replace-builtin-strlen-that-appears-to-get-optimized.patch lib_patch.Upstream\n-configs/am574x_idk_defconfig lib_defconfig.ForceCheckHash\n configs/arcturus_ucls1012a_defconfig lib_defconfig.ForceCheckHash\n configs/arcturus_ucp1020_defconfig lib_defconfig.ForceCheckHash\n configs/asus_tinker-s_rk3288_defconfig lib_defconfig.ForceCheckHash\ndiff --git a/board/ti/am574x-idk/extlinux.conf b/board/ti/am574x-idk/extlinux.conf\nindex 29e0ecfa14..4faa8f7eed 100644\n--- a/board/ti/am574x-idk/extlinux.conf\n+++ b/board/ti/am574x-idk/extlinux.conf\n@@ -1,4 +1,4 @@\n label am5749-idk-buildroot\n kernel /zImage\n fdtdir /\n- append console=ttyS0,115200n8 root=/dev/mmcblk0p2 rw rootfstype=ext4 rootwait\n+ append console=ttyS2,115200n8 root=/dev/mmcblk0p2 rw rootfstype=ext4 rootwait\ndiff --git a/board/ti/am574x-idk/genimage.cfg b/board/ti/am574x-idk/genimage.cfg\nindex 02a9ffe013..e7ab22f29b 100644\n--- a/board/ti/am574x-idk/genimage.cfg\n+++ b/board/ti/am574x-idk/genimage.cfg\n@@ -4,9 +4,11 @@ image boot.vfat {\n \t\t\t\"MLO\",\n \t\t\t\"u-boot.img\",\n \t\t\t\"zImage\",\n-\t\t\t\"am574x-idk.dtb\",\n+\t\t\t\"ti\",\n \t\t\t\"extlinux\"\n \t\t}\n+\n+\t\tlabel = \"boot\"\n \t}\n \n \tsize = 16M\n@@ -25,6 +27,5 @@ image sdcard.img {\n \tpartition rootfs {\n \t\tpartition-type = 0x83\n \t\timage = \"rootfs.ext4\"\n-\t\tsize = 1G\n \t}\n }\ndiff --git a/board/ti/am574x-idk/patches/linux/linux.hash b/board/ti/am574x-idk/patches/linux/linux.hash\nnew file mode 100644\nindex 0000000000..020dc72386\n--- /dev/null\n+++ b/board/ti/am574x-idk/patches/linux/linux.hash\n@@ -0,0 +1,2 @@\n+# From https://www.kernel.org/pub/linux/kernel/v6.x/sha256sums.asc\n+sha256 f4855f382c1b735c84072bdef36db5bcd5dc7b0c37e42f5104317149a0a486ef linux-6.18.18.tar.xz\ndiff --git a/board/ti/am574x-idk/patches/uboot/uboot.hash b/board/ti/am574x-idk/patches/uboot/uboot.hash\nnew file mode 100644\nindex 0000000000..36322a6a90\n--- /dev/null\n+++ b/board/ti/am574x-idk/patches/uboot/uboot.hash\n@@ -0,0 +1,2 @@\n+# Locally calculated\n+sha256 ac7c04b8b7004923b00a4e5d6699c5df4d21233bac9fda690d8cfbc209fff2fd u-boot-2026.04.tar.bz2\ndiff --git a/configs/am574x_idk_defconfig b/configs/am574x_idk_defconfig\nindex 5d3ec12ad6..fd8bb4982b 100644\n--- a/configs/am574x_idk_defconfig\n+++ b/configs/am574x_idk_defconfig\n@@ -1,23 +1,29 @@\n BR2_arm=y\n BR2_cortex_a15=y\n-BR2_PACKAGE_HOST_LINUX_HEADERS_CUSTOM_6_6=y\n+BR2_TOOLCHAIN_EXTERNAL=y\n+BR2_TOOLCHAIN_EXTERNAL_BOOTLIN=y\n+BR2_TOOLCHAIN_EXTERNAL_BOOTLIN_ARMV7_EABIHF_GLIBC_STABLE=y\n+BR2_GLOBAL_PATCH_DIR=\"board/ti/am574x-idk/patches\"\n+BR2_DOWNLOAD_FORCE_CHECK_HASHES=y\n BR2_SYSTEM_DHCP=\"eth0\"\n BR2_ROOTFS_POST_BUILD_SCRIPT=\"board/ti/am574x-idk/post-build.sh\"\n BR2_ROOTFS_POST_IMAGE_SCRIPT=\"support/scripts/genimage.sh\"\n BR2_ROOTFS_POST_SCRIPT_ARGS=\"-c board/ti/am574x-idk/genimage.cfg\"\n BR2_LINUX_KERNEL=y\n BR2_LINUX_KERNEL_CUSTOM_VERSION=y\n-BR2_LINUX_KERNEL_CUSTOM_VERSION_VALUE=\"6.6.14\"\n+BR2_LINUX_KERNEL_CUSTOM_VERSION_VALUE=\"6.18.18\"\n BR2_LINUX_KERNEL_DEFCONFIG=\"multi_v7\"\n BR2_LINUX_KERNEL_DTS_SUPPORT=y\n BR2_LINUX_KERNEL_INTREE_DTS_NAME=\"ti/omap/am574x-idk\"\n+BR2_LINUX_KERNEL_DTB_KEEP_DIRNAME=y\n BR2_LINUX_KERNEL_NEEDS_HOST_OPENSSL=y\n BR2_TARGET_ROOTFS_EXT2=y\n BR2_TARGET_ROOTFS_EXT2_4=y\n+BR2_TARGET_ROOTFS_EXT2_SIZE=\"256M\"\n BR2_TARGET_UBOOT=y\n BR2_TARGET_UBOOT_BUILD_SYSTEM_KCONFIG=y\n BR2_TARGET_UBOOT_CUSTOM_VERSION=y\n-BR2_TARGET_UBOOT_CUSTOM_VERSION_VALUE=\"2024.01\"\n+BR2_TARGET_UBOOT_CUSTOM_VERSION_VALUE=\"2026.04\"\n BR2_TARGET_UBOOT_BOARD_DEFCONFIG=\"am57xx_evm\"\n BR2_TARGET_UBOOT_NEEDS_DTC=y\n BR2_TARGET_UBOOT_NEEDS_OPENSSL=y\n","prefixes":[]}
