I’m testing the HW interfaces of iMX8 after flashing the Yocto linux image with BSP5
I noticed in the device tree that the current SPI interfaces use GPIO chip-select instead of the native cs
By modifying it to use the native chip-select to avoid the delays that comes with GPIO cs, I got the following:
The chip select’s behaviour seem like the clock instead of being stable 0 during the transfer period.
does the native chip-select work properly in the current SPI driver of BSP5?
