The IP Command Read didn't work correct on my target. In the source code of the linux driver I have seen the following command.



Linux/drivers/mtd/spi-nor/fsl-quadspi.c   V4.8   line 668

* The IC guy suggests we use the "AHB Command Read" which is faster then the "IP Command Read". 
(What's more is that there is a bug in
he "IP Command Read" in the Vybrid.)


In my case, the handling with the LUT table and the configuration for an IP initiated command works correct (none error flags detected) but unfortunately none pin activations will be happens (the Pin selection was be done correct in the RCW section)


  • Is there exist any errata sheets ot the ls1021A
  • Do you have any source examples for the QuadSPI on the ls1021A platform different than the LINUX code
