Error in STM32WL5MOC User Manual (UM3127, rev 3, Jan 2025)

[jcwren]

There is an error in table 17 on page 33 in regards to two of the pin positions for the MB1880A adapter.  Table 17 states that pin 2 is SPI1_MOSIP (PA7) / UART1_TX (PC1) and pin 3 is SPI1_MISOP (PA6) / UART1_RX (PC0).  These two pins are reversed in both the CN2 and CN3 columns.

In actuality, pin 2 is SPI1_MOSIP (PA7) / UART1_RX (PC0) and pin 3 is SPI1_MISOP (PA6) / UART1_TX (PC1). 

This is confirmed by table 13 (page 28), the MB1779 schematic (MB1779-HIGH-BAND-B02 Board schematic under the B-WL5M-SUBG1 CAD Resources tab), and wasting an hour trying to determine why the I2C3 port was not talking to a device.

Hello @jcwren 

It is a typo on the doc. @Imen.D could you please report this typo and move the post to the wireless forum since it is related to a wireless product.

Best Regards.
