Shouldn't we instead create a Buildroot package that would
download/extract/install this firmware image, and put it in the FAT
partition ?

Thanks!

Fabio, do you have any comment about this ?

In the mean time, I'll mark the patch as Changes Requested.

I agree with you that we should create a Buildroot package that
handles the Cortex-M4 FreeRTOS binary.

I will work on it when I am back from vacation.

Thanks

+****************************
+Freescale i.MX7ULP EVK board
+****************************
+
+This file documents the Buildroot support for the Freescale i.MX7ULP EVK board.
+
+First, configure Buildroot for your i.MX7ULP EVK board:
+
+	$ make freescale_imx7ulp-evk_defconfig
+	$ make
+
+Buildroot prepares a bootable "sdcard.img" image in the output/images/
+directory, ready to be dumped into an SD card:
+
+sudo dd if=output/images/sdcard.img of=/dev/<your-microsd-device>; sync
+
+i.MX7ULP has a Cortex-A7 and a Cortex-M4.
+
+Important: Cortex-M4 must be programmed to enable PMIC to correct boot
+Linux in the Cortex-A7.
+
+Step 1 - Download the Cortex-M4 pre-compiled binary:
+
+	wget https://www.nxp.com/lgfiles/NMG/MAD/YOCTO/imx7ulp-m4-demo-2.4.0.bin
+
+Step 2: Extract the example files:
+
+	$ chmod a+x imx7ulp-m4-demo-2.4.0.bin
+	$  ./imx7ulp-m4-demo-2.4.0.bin
+
+Step 3: Copy the imx7ulp_m4_demo.img binary to the FAT partion of MicroSD card.
+
+Step 4: Insert the MicroSD card on the board, open 2 terminals at 115200 bps,
+8n1
+
+	First terminal (Cortex-A7): 	/dev/ttyUSB0
+	Second terminal (Cortex-M4):	/dev/ttyUSB1
+
+Step 5: Power on the board and, on first terminal ttyUSB0, stop at U-Boot. 
+	To flash the QSPI memory with the pre-built Cortex-M4 binary,run 
+	the commands below:
+   
+=> sf probe
+=> sf erase 0x0 0x20000
+=> fatload mmc 0:1 0x62000000 imx7ulp_m4_demo.img
+=> sf write 0x62000000 0x0 0x20000
+
+Step 6: Power cycle the board:
+
+	- The first terminal ttyUSB0 communicates with Cortex-A7 and will
+show the Linux boot.
+
+	- The second terminal ttyUSB1 communicates with Cortex-M4 running the 
+"Power Mode Switch Task" application.
