Hello,
there seem to be an error in the User Manual UM3359 of the Evaluation board with STM32MP257F MPU.
In the Section 8.1.1 Description
"The LD11 LED turns green when the power cable is inserted into the CN2 or CN21 connector.
Two general-purpose color LEDs (LD4 and LD3) are available as light indicators:
• The blue LED (LD4) is used as the Linux® Heartbeat LED, which is blinking as long as Linux® is alive on
the Cortex®-A.
• The orange LED (LD3) is used as a STM32Cube example verdict LED.
The two indicator LEDs, the red (LD4) and green (LD7) LEDs are either connected to the STM32MP257 MPU.
The LEDs (LD5 and LD6) are used as ST-LINK indicator status. Refer to Section 7.4.6."
The errors are colored in red:
-LD4 is blue, not read.
-LD7 is not connected to the STM32MP257 MPU but to the RJ45_48F-01GYDXNL
-The LEDs LD1 and LD2 are not mentioned in the description. Only in the section 8.1.3 LED interface. In the first page it says "four user LEDs", but in the block diagram there are only "2 User LEDs". When I connect the board LD1 (red) is blinking, so I am not sure which LEDs I can use for to the Blinking test.
-Is "example verdict" right? For me it doesn't make sense.
I hope someone can help and that the mistakes in the User Manual are corrected.
Thanks in advance.
