IDW04A1 missing cs on CN5

I wish to connect an IDW04a1 Board to the Discovery kit for IOT node (B-L475E-IOT01A) to replace the Inventek WiFi module with a SPWF04SA WiFi module. It appears that the NSS/nCS/WAKEUP* signal is not routed correctly to CN5-Pin3 from Pin9 of the SPWF04SA module.In fact R33 is not mounted. The signal is routed to GPIO1 but that signal does not go to CN5.

Also, the MISO signal from SPWF04SA-Pin6 is routed to CN5-Pin5 and not CN5-Pin1.

Table 10 in UM2183 appears incorrect for the MISO and NSS signals.

Has anyone else noticed these issues?

CN5-Pin5 (aka D12 MISO) seems consistent with other Arduino implementations.

>>Table 10 in UM2183 appears incorrect for the MISO and NSS signals.

The CN5-Pin 1 seems to be a sloppy cut-n-paste from Table 9

D11 (CN5.4) MOSI GPIO14

D12 (CN5.5) MISO GPIO13

D13 (CN5.6) SCLK GPIO15

A4 (CN8.5) GPIO6

The SPI chip selects don't look to be on D10

Hello,

Thank you for bringing this to our attention.

I will raise your feedback to the appropriate team to correct the user manual.
