There are 1 incomplete or pending task to finish installation of Semantic MediaWiki. An administrator or user with sufficient rights can complete it. This should be done before adding new data to avoid inconsistencies.1. Introduction[edit source]
The following paragraphs describe the functional mapping of the LEDs and buttons.
2. Description[edit source]
2.1. LEDs[edit source]
LED color | Purpose |
---|---|
Green |
Can be used at runtime for Linux examples |
Red |
Used to show Cortex-A boot information[1] |
Blue | U-Boot entering / exit indication then Linux heartbeat, which blinks as long as Linux[2] is alive[1] on the Cortex-A |
Orange | Used for STM32Cube[3] examples verdict, on STM32MP15. Free for user on STM32MP13. |
2.2. Buttons[edit source]
Button label | Purpose |
---|---|
WAKE UP | Allows the platform to be woken from any low-power mode[4] |
USER1 |
Used at boot time by U-Boot to enter USB programming mode with STM32CubeProgrammer. This avoids manipulation of the boot pins when a valid U-Boot image is already present in the board. Can be used at runtime for Linux examples or STM32Cube examples, on STM32MP15. |
USER2 |
Used at boot time by U-Boot to enter Android Fastboot mode. Used at runtime for Linux, on STM32MP13. |
TAMPER | Allows to generate an external tamper event. Only present on STM32MP13 board. |
3. On STM32MP13x lines [edit source]
You can refer to the respective board-hardware descriptions to determine to which GPIO each function is mapped:
4. On STM32MP15x lines [edit source]
You can refer to the respective board-hardware descriptions to determine to which GPIO each function is mapped:
- STM32MP157x-EV1 - hardware description for the Evaluation boards
- STM32MP157x-DKx - hardware description for the Discovery kits.
