configs/imx8mpico: remove defconfig
This defconfig fail to build since commit dc0f721
"package/gcc: switch to 13.x as default".
This board is no longer listed in the supported platforms in the
latest BSPs from TechNexion:
https://developer.technexion.com/docs/release-notes-yp42-2024q2#supported-platforms-in-this-release
This commit removes this defconfig.

Subject: [PATCH] fix(build): allow lower address access with gcc-12
|
||||
|
||||
With gcc-12 any lower address access can trigger a warning/error
|
||||
this would be useful in other parts of system but in TF-A
|
||||
there are various reasons to access to the lower address ranges,
|
||||
example using mmio_read_*/writes_*
|
||||
|
||||
So setup to allow access to lower addresses while using gcc-12

Subject: [PATCH] feat(build): add support for new binutils versions
|
||||
|
||||
Users of GNU ld (BPF) from binutils 2.39+ will observe multiple instaces
|
||||
of a new warning when linking the bl*.elf in the form:
|
||||
|
||||
ld.bfd: warning: stm32mp1_helper.o: missing .note.GNU-stack section implies executable stack
|
||||
ld.bfd: NOTE: This behaviour is deprecated and will be removed in a future version of the linker
|
||||
ld.bfd: warning: bl2.elf has a LOAD segment with RWX permissions
|
||||
ld.bfd: warning: bl32.elf has a LOAD segment with RWX permissions
|
||||
|
||||
These new warnings are enbaled by default to secure elf binaries:
|
||||

|
||||
|
||||
Fix it in a similar way to what the Linux kernel does, see:
|
||||
https://lore.kernel.org/all/20220810222442.2296651-1-ndesaulniers@google.com/
|
||||
|
||||
Following the reasoning there, we set "-z noexecstack" for all linkers
|
||||
(although LLVM's LLD defaults to it) and optional add
|
||||
--no-warn-rwx-segments since this a ld.bfd related.

Technexion i.MX8M Pico board
|
||||
****************************
|
||||
|
||||
This file documents the Buildroot support for the Technexion i.MX8M
|
||||
Pico board. The Pico i.MX8M system-on-module [1] is present in
|
||||
development kits like the Pico Pi i.MX8M [2].
|
||||
|
||||
Build
|
||||
=====
|
||||
|
||||
First, configure Buildroot for the i.MX8M Pico board:
|
||||
|
||||
make imx8mpico_defconfig
|
||||
|
||||
Build all components:
|
||||
|
||||
make
|
||||
|
||||
You will find in output/images/ the following files:
|
||||
- bl31.bin
|
||||
- boot.vfat
|
||||
- Image
|
||||
- imx8-boot-sd.bin
|
||||
- lpddr4_pmu_train_fw.bin
|
||||
- pico-8m-dcss-ili9881c.dtb
|
||||
- pico-8m.dtb
|
||||
- rootfs.ext4
|
||||
- sdcard.img
|
||||
- signed_hdmi_imx8m.bin
|
||||
- u-boot.imx
|
||||
|
||||
Flashing sdcard.img on the eMMC
|
||||
===============================
|
||||
|
||||
i.MX8M Pico board does not have a SD card slot. The storage is an
|
||||
eMMC. An easy way to flash the eMMC is to use the u-boot ums
|
||||
command. The boards are sold pre-flashed with such a u-boot. It is
|
||||
assumed here that the board has already a working u-boot on eMMC and
|
||||
jumpers are set to boot on eMMC. See [3].
|
||||
|
||||
Jumper configuration for eMMC boot:
|
||||
J1: jumper on pins 4 and 6.
|
||||
J2: jumper on pins 2 and 4.
|
||||
|
||||
In case the board was flashed with a wrong u-boot, or the eMMC is
|
||||
erased, u-boot can be loaded by USB Serial Download boot mode, using
|
||||
imx-usb-loader. See [3].
|
||||
|
||||
For flashing:
|
||||
- Plug the micro USB cable from the Debug USB Port, to your computer
|
||||
- Plug the USB Type C to your computer, this will power up the board
|
||||
|
||||
In the U-Boot prompt launch:
|
||||
|
||||
=> ums 0 mmc ${mmcdev}
|
||||
|
||||
This will mount the eMMC content in the host PC as a mass storage device.
|
||||
Note: the ${mmcdev} id may change from one uboot version to another. The
|
||||
actual id can be confirmed by running commands "mmc rescan" then
|
||||
"mmc list", to find the eMMC entry. Finally it's possible to enter
|
||||
directly the mmc device id, for example: "ums 0 mmc 2".
|
||||
|
||||
To determine the device associated to the eMMC card have a look in the
|
||||
/proc/partitions file:
|
||||
|
||||
cat /proc/partitions
|
||||
|
||||
If your system automatically mount some device partitions, make sure
|
||||
to unmount them.
|
||||
|
||||
Buildroot prepares a bootable "sdcard.img" image in the output/images/
|
||||
directory, ready to be dumped on the eMMC. Launch the following
|
||||
command as root:
|
||||
|
||||
dd bs=1M if=output/images/sdcard.img of=/dev/<your-sd-device>
|
||||
|
||||
*** WARNING! This will destroy all the eMMC content. Use with care! ***
|
||||
|
||||
This operation can take several minutes, depending on the image
|
||||
size. When tested, a 10MB/s transfer rate was observed. Note: the
|
||||
blocksize "bs=1M" parameter gives better transfer performances.
|
||||
|
||||
For details about the medium image layout, see the definition in
|
||||
board/freescale/common/imx/genimage.cfg.template.
|
||||
|
||||
Boot the i.MX8M Pico board
|
||||
==========================
|
||||
|
||||
To boot your newly created system:
|
||||
- put a micro USB cable into the Debug USB Port and connect using a terminal
|
||||
emulator at 115200 bps, 8n1;
|
||||
- power on the board, with USB Type C connector.
|
||||
|
||||
Enjoy!
