Hello Roberto, It would be good if you can dump assembly that is generated. What I see is that "int spi_register(FAR struct spi_dev_s *spi, int bus)", so I'm assuming that R0 should be "spi" and R1 should be "bus", but in your dump "R0: 00000001 R1: 2004e840" those seems to be inverted (00000001 seems to be a "bus" and "2004e840" seems to be a "spi" pointer). The assembly code will show light on the dump that you provided. As an alternative you can provide the defconfig that you use if you are not using a custom board.
