Using STM32 Cube Programmer

STM32 Cube Programmer is a utility provided by ST that allows to reflash an STM32MP1 platform directly from your PC.

To get started, download STM32 Cube Programmer from the ST website. We tested with version 2.16.0, and the below instructions assume that STM32 Cube Programmer is installed in the $HOME/stm32cube folder.

STM32 Cube Programmer will be used to reflash the SD card, with the SD card inserted in the STM32MP1 platform.

The following procedure (done for the stm32mp157f-dk2 profile) is also valid for stm32mp135f-dk and the demo profiles.

Follow these steps:

1. Switch the boot mode switch SW1 to USB boot
2. Plug a second USB-C cable on CN7
3. Copy images in a dedicated folder

$ mkdir flash
$ cp bin/targets/stm32/stm32mp1/trusted-firmware-a-stm32mp157f-dk2/tf-a-stm32mp157f-dk2.stm32 flash/
$ cp staging_dir/target-arm_cortex-a7+neon-vfpv4_musl_eabi/image/fip-stm32mp157f-dk2.bin flash/
$ cp bin/targets/stm32/stm32mp1/openwrt-stm32-stm32mp1-stm32mp157f-dk2-ext4-factory.img.gz flash/

4. Decompress the factory image

$ gzip -d flash/openwrt-stm32-stm32mp1-stm32mp157f-dk2-ext4-factory.img.gz

5. Create the flash.tsv file

$ cat flash/flash.tsv
-	0x01	fsbl-boot	Binary	none	0x0	tf-a-stm32mp157f-dk2.stm32
-	0x03	fip-boot	FIP	none	0x0	fip-stm32mp157f-dk2.bin
P	0x10	sdcard		RawImage	mmc0	0x0	openwrt-stm32-stm32mp1-stm32mp157f-dk2-ext4-factory.img

6. Run the command to start flashing

$ $HOME/stm32cube/bin/STM32_Programmer_CLI -c port=usb1 -w ./flash/flash.tsv

7. Switch back the boot mode switch to SD boot
8. Reboot the platform
