[U-Boot] [PATCH 2/2] Add i.MX7D based Meerkat96 board support
Shawn Guo
shawn.guo at linaro.org
Sun Jul 7 12:59:55 UTC 2019
The Meerkat96 board, based on the NXP i.MX7D SoC, is a member of
96Boards community and complies with all Consumer Edition board
specifications.
https://www.novtech.com/products/meerkat96.html
https://www.96boards.org/product/imx7-96/
The initial supported/tested devices include:
- Debug serial
- SD
- USB Host (with Ethernet)
With these support, it's good enough for loading Linux Kernel from SD or
Ethernet over USB.

+* Build U-Boot for Meerkat96 board
+
+ $ make mrproper
+ $ make meerkat96_defconfig
+ $ make
+
+ It will generate the U-Boot binary called u-boot-dtb.imx
+
+* Install U-Boot to MicroSD card
+
+ Plug MicroSD card to a Linux machine (with card reader), find the
+ device name and replace sd[x] with the name in the following command.
+
+ $ sudo dd if=u-boot-dtb.imx of=/dev/sd[x] bs=512 seek=2
+
+ It will install U-Boot to MicroSD card at 1KiB offset. Insert the
+ card to Meerkat96 MicroSD slot, power up the board, and U-Boot should
+ boot from the card.
