Discrepancy in STM32MP257F-EV1 User Manual Regarding USER2 Button GPIO Mapping

[embman]

Dear STMicroelectronics Support Team,

I am currently working with the STM32MP257F-EV1 evaluation board and have encountered a discrepancy in the user manual (UM3359, Rev 2, October 2024) concerning the GPIO mapping of the USER2 button.

In Table 8 of the manual, the USER2 button (B4) is listed as connected to PA13. However, Table 32 correctly indicates that the USER2 button is connected to PG8, which aligns with the board's schematic and my practical observations. Pressing the USER2 button triggers the expected behavior associated with PG8, while PA13 does not respond as described.

This inconsistency could potentially lead to confusion for developers referencing the manual. I kindly request that this discrepancy be reviewed and corrected in future revisions of the documentation.

Thank you for your attention to this matter.

Best regards,

Adnan

ps: I could not find anyway to send a correction request to any emails, so here it is for everyone to know in advance.
