Can not read JEDEC id for nor flash m25p32?

[youyong]

m25p32 spi0.0: unrecognized JEDEC id bytes: 00,  0,  0;

The CPU is imx6dl,the platform is linux.

There is a nor flash with SPI1,then we can see a device node(spidev0.0) under the floder of dev.But the JEDEC id bytes: are 00,  0,  0.Why

Hi you

please look at dts example (&ecspi1 { ..flash: m25p80@0 { ..) in imx6qdl-sabresd.dtsi
linux-imx.git - i.MX Linux Kernel 
check sect.31.1.5 Menu Configuration Options in Chapter 31 SPI NOR Flash Memory
Technology Device (MTD) Driver attached Linux Manual

Best regards
igor
