On ls1021a, qspi pins muxed with some pins of IFC. You could refer to the RCW field descriptions in LS1021A RM.

In LSDK QSPI and IFC(NOR, NAND) cannot be used simultaneously.

In your Linux Kernel booting up log, I didn't find the following message.

root@ls1021atwr:~# dmesg | grep ifc
[ 0.070784] fsl-ifc 1530000.memory-controller: Freescale Integrated Flash Controller
[ 0.070842] fsl-ifc 1530000.memory-controller: IFC version 1.4, 8 banks

Your dts file looks reasonable, please check your Kernel configuration file whether "CONFIG_FSL_IFC=y" is enabled.

Hello, I have

CONFIG_FSL_IFC=y

in my kernel config, I can see ifc nand in kernel boot log with sdcard boot (but can't see any qspi logs), but when I try to do it with qspi boot, there are no logs about ifc at all.

Hello @yipingwang ,

I'm in the same situation, qspi boot (with nand accessible in u-boot) but in the kernel IFC is not probed.

 

Where do you found this information ? I don't see this anywhere. Why is it working in u-boot and not in linux ?

LSDK QSPI and IFC(NOR, NAND) cannot be used simultaneously

Here is my schema of the board

Do you know how can I use the nand flash?

Thank you

Thank you, I understand.

Can you help me with another question with the nand memory, is there any flash soft like mfgtools for the layerscape processors?
