Raw SPI on TWR-LS1021A

[stuartrubin]

We need get access to raw SPI (or QSPI) reads and writes on SPI bus that the NOR flash sits on on the TWR-LS1021A board. Can someone please tell me the definitive steps to get a /dev/spi0, use spidev, etc.? We are currently building the kernel, dtb, roots, with Yocto. Thank you!

Thank you, Pavel. DSPI and QPSI are enabled, but I cannot get a /dev/spixxx device in the tree. Thank you.

Check the LS1021a DSPI and QSPI enabling in kernel menu.

Have a great day,
Pavel Chubakov
