Julien Olivain 956c5224ab configs/freescale_imx7dsabresd: bump BSP components to lf-6.6.23-2.0.0 This commit bumps U-Boot and Linux kernel to the NXP BSP lf-6.6.23-2.0.0 versions. While bumping those BSP components, this commit also adds the custom hashes by enabling BR2_DOWNLOAD_FORCE_CHECK_HASHES=y in this defconfig. A _PATCH_DIR is added for that purpose and hash files are added in it. The ".checkpackageignore" entry for this defconfig is also removed. Also, since commit `dc0f721` "package/gcc: switch to 13.x as default", this freescale_imx7dsabresd_defconfig is failing to build the Kernel with output: drivers/ata/libahci.c: In function 'ahci_led_store': ././include/linux/compiler_types.h:315:45: error: call to '__compiletime_assert_340' declared with attribute error: BUILD_BUG_ON failed: sizeof(_s) > sizeof(long) 315 \| _compiletime_assert(condition, msg, __compiletime_assert_, __COUNTER__) \| ^ This commit fixes the issue by bumping components which includes the needed gcc-13 fixes. The Kernel DTS name is also updated by adding the new "nxp/imx/" prefix, to follow the upstream reorganization in [1], first included in v6.5.

***************************
Freescale i.MX7D SDB board
***************************

This file documents the Buildroot support for the Freescale i.MX7D SDB board.

Build
=====

First, configure Buildroot for your i.MX7D SDB board:

  make freescale_imx7dsabresd_defconfig

Build all components:

  make

You will find in output/images/ the following files:
  - imx7d-sdb.dtb
  - rootfs.ext4
  - rootfs.tar
  - sdcard.img
  - u-boot.imx
  - zImage

Create a bootable SD card
=========================

To determine the device associated to the SD card have a look in the
/proc/partitions file:

  cat /proc/partitions

Buildroot prepares a bootable "sdcard.img" image in the output/images/
directory, ready to be dumped on a SD card. Launch the following
command as root:

  dd if=./output/images/sdcard.img of=/dev/<your-sd-device>

*** WARNING! This will destroy all the card content. Use with care! ***

For details about the medium image layout, see the definition in
board/freescale/common/imx/genimage.cfg.template.

Boot the i.MX7D SDB board
=========================

To boot your newly created system:
- insert the SD card in the SD slot of the board;
- put a micro USB cable into the Debug USB Port and connect using a terminal
  emulator at 115200 bps, 8n1;
- power on the board.

Enjoy!
