Since uClibc was bumped to 1.0.58 (c7fef3704c, "package/uclibc:
bump to 1.0.58"), the board hangs after starting init:
[ 1.231624] Run /sbin/init as init process
[ 1.235599] with arguments:
[ 1.238549] /sbin/init
[ 1.241331] earlyprintk
[ 1.244018] with environment:
[ 1.247143] HOME=/
[ 1.249554] TERM=linux
[ 1.252177] consoleblank=0
No error message is printed and the boot simply stalls at this
point.
The STM32F769 has no MMU, and uClibc's standard malloc()
implementation returns NULL for allocations performed during early
init on this target, causing init to fail.
Fix this by switching to MALLOC_SIMPLE, a plain mmap-based allocator
meant for small/noMMU systems, via a uClibc config fragment. Unlike
the STM32F429/STM32F469 fix, the fragment is kept board-specific
since the STM32F769 is a Cortex-M7 board and does not belong to the
stm32f4xx family.

The STM32F429 has no MMU, and uClibc's standard malloc() implementation
returns NULL for allocations performed during early init on this target,
causing init to abort immediately.
Fix this by switching to MALLOC_SIMPLE, a plain mmap-based allocator
meant for small/noMMU systems, via a uClibc config fragment. The
fragment is placed under board/stmicroelectronics/common/stm32f4xx/,
rather than under the board-specific directory, so that it can be
shared with the STM32F469, another Cortex-M4/noMMU board affected by
the same issue, which will be fixed in a subsequent patch.

"load hostfs" generic command as suggested by the documentation [2].
This commit adds BR2_TARGET_UBOOT_NEEDS_DTC=y, because the new

failures on hosts with libyaml (uboot builds its own dtc if none is

UEFI platforms with a Devicetree have recently gained support for some form
of network booting. [1][2]
On those platforms, the UEFI firmware downloads the disk image over the
network and presents it to UEFI applications using the simple filesystem
protocol. This is sufficient for OS loaders such as e.g. GRUB to find their
configuration and load the kernel image.
The firmware must also describe the ramdisk to the OS, so that it finds its
root filesystem. On ACPI based platforms this is done with an NVDIMM
Firmware Interface Table (NFIT). On Devicetree based platforms, this can be
done with a pmem node. [3]
Add a kernel config fragment to add pmem support, which enables network
boot on UEFI platforms with Devicetree.
Also, briefly mention that we support this scenario in the readme.
This can be tested on Qemu, with the following procedure:
Build aarch64_efi_defconfig in a folder, to obtain output/images/disk.img,
and serve the image over HTTP with python:
$ python -m http.server -d output/images/
In another terminal and another folder, configure a U-Boot based firmware
starting from qemu_aarch64_ebbr_defconfig, and with the following
additional configurations:
BR2_TARGET_UBOOT_CUSTOM_VERSION_VALUE="2026.04"
BR2_TARGET_UBOOT_NEEDS_DTC=y
Add the following U-Boot configurations to
board/qemu/aarch64-ebbr/u-boot.fragment:
CONFIG_EFI_HTTP_BOOT=y
CONFIG_NET_LWIP=y
Build everything; you should obtain output/images/flash.bin.
Start Qemu as per board/qemu/aarch64-ebbr/readme.txt, but omitting the hd0
-device and -drive stanzas.
U-Boot should start; interrupt it with enter.
At U-Boot prompt, type the following commands:
=> setenv loadaddr 0x43000000
=> efidebug boot rm 0
=> efidebug boot add -u 0 net http://10.0.2.2:8000/disk.img
=> efidebug boot order 0
=> bootefi bootmgr
U-Boot should download the disk image over HTTP and boot Linux with UEFI.
Look for the following message in Linux boot log, to confirm that it did
indeed mount its rootfs from the downloaded image:
EXT4-fs (pmem0p2): mounted filesystem ...

- enable BR2_DOWNLOAD_FORCE_CHECK_HASHES=y, add custom hashes stored

- enable BR2_LINUX_KERNEL_DTB_KEEP_DIRNAME=y to install the board
devicetree in the boot (vfat) partition keeping the directory
prefixes (ti/omap/am574x-idk.dtb). u-boot nowadays is looking for

Update genimange.cfg file accordingly.
- While at it, add a label to the boot (vfat) partition to not use a
generated label.
- set BR2_TARGET_ROOTFS_EXT2_SIZE="256M" since the rootfs no longer
fit in the default size (60M).
- Remove the rootfs partition predefined 1G size to avoid a parted
warning about "unallocated space within the partition."
- Update extlinux.conf kernel command line to use "console=ttyS2"
instead of "ttyS0". Seems a typo introduced with the defconfig
(AM57xx always used ttyS2 as kernel console).
