SPI1 in Arduino fails

Technical Discussion
1

in a custom board with module rtl8735b I cannot seem to configure SPI1 in arduino. Pin mapping looks correct but when running I get:

[MISC Err]Pin 5[8] is conflicted
[MISC Err]It’s configured as GPIO now.
[MISC Err]It’s using by peripheral F0000000
[SSI Err]PIN a8 cannot be registered.
[SSI Err]spi_format(): SPI 1 init fails.
[SSI Err]Please initialize SPI format first!

seems solved, was a config issue of SPI always changing SPI1_SS pin…
