"UM2407 Rev 3 User manual", table 18, "CN7 ZIO Connector pinout" pin name of pin 14 wrong

[marco239955_stm1]

Hi,

while doing a symbol for the Nucleo in KiCad I found that the Pin CN7.14 should be PA7 instead PB5.

The sub-note (3) is correct.

Best regards

Hello @marco239955_stm1 

According to the UM2407 rev03 Table 14. Solder bridge and jumper configuration, the Pin14 of CN7 is connected to STM32H7 PB5 if the solder bridge SB33 is off and the solder bridge SB35 is on (default configuration). And the Pin14 of CN7 is connected to STM32H7 PA7 if the solder bridge SB35 is off and the solder bridge SB33 is on.(look at the third line of the table :backhand_index_pointing_down::

Then the Table 8 indicate the default configuration. 

And the note below the table ask you to take more information by looking at the table 14.(the note(1))

Best regards.

Hi Issamos,

thank you for the hint.

I also had a look in the schematics of board, where it is more clear to see than in the sentence

"3. PA7 is used as D11 and connected to CN7 pin 14. If SB31 is ON, it is also connected to Ethernet PHY as RMII_CRS_DV. In this case, only one function of the Ethernet or D11 must be used."

Best regards
