# Using STM32 Cube Programmer
|
|
|
|
Applicable platforms: STM32MP157-DK1, STM32MP157-DK2, STM32MP135-DK
|
|
|
|
[STM32 Cube
|
|
Programmer](https://www.st.com/en/development-tools/stm32cubeprog.html)
|
|
is a utility provided by ST that allows to reflash an STM32MP1
|
|
platform directly from your PC. It is particularly useful if the
|
|
storage used on your STM32MP1 platform is non-removable, such as an
|
|
eMMC or NAND flash. STM32 Cube Programmer uses USB connectivity with
|
|
the STM32MP1 platform to do the reflashing, and it works even if the
|
|
STM32MP1 platform has no software installed.
|
|
|
|
To get started, download STM32 Cube Programmer from the [ST
|
|
website](https://www.st.com/en/development-tools/stm32cubeprog.html). It
|
|
unfortunately requires having an account on *st.com*. We tested with
|
|
version 2.8.0, and the below instructions assume that STM32 Cube
|
|
Programmer is installed in the `$HOME/stm32cube` folder.
|
|
|
|
As the STM32MP157-DK1/DK2 or the STM32135F-DK do not provide any
|
|
non-removable storage device, our demonstration will use the SD card:
|
|
STM32 Cube Programmer will be used to reflash the SD card, with the SD
|
|
card inserted in the STM32MP1 platform.
|
|
|
|
Follow these steps:
|
|
|
|
1. Switch the boot mode switch SW1 to USB boot
|
|
2. Plug a second USB-C cable on CN7
|
|
3. Run these commands to flash the SDCard:
|
|
```bash
|
|
$ cd output/images/
|
|
$ sudo ~/stm32cube/bin/STM32_Programmer_CLI -c port=usb1 -w flash.tsv
|
|
```
|
|
4. Switch back the boot mode switch to SD boot
|
|
5. Reboot the platform
|
|
|
|
The `flash.tsv` file has been produced by Buildroot and tells STM32
|
|
Cube Programmer what to flash. If you want to reflash an eMMC storage
|
|
device instead, this `flash.tsv` file will have to be adapted.
