QSPI NOR memory support in Linux

bou6 — Mon, 16 Aug 2021 17:08:39 GMT

I am using S32g eval board and Linux bsp24, I want to to write and read from Qspi Nor memory, normally that should be supported by the mtd driver, but what I noticed is: first there is no qspi node in the dts file, second the mtd device files under /dev are not created.

My questions :

1- How is writing and reading in qspi Nor is handled ?

2- Can you please share basic examples for reading and writing in the QSPI Nor Memory ?

You are using a BSP release which is very much obsolete. Consider moving to
the most recent BSP 29 HF1. Visit this link to enter the SDK download procedure. See BSP 29 HF1 User Manual Section 3.2.5.2 on how to write to
QSPI-based MTD partitions and boot from it.

Hope this helps,
