ls1021a IFC NAND with QSPI boot issue

[kele6ra]

Hello, we have custom ls1021a board. We want to make qspi boot (nor flash) and ifc nand kernel+rootfs. The main problem that I don't see even ifc device probing with the kernel logs.

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.

[yipingwang · Accepted solution]

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.

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

RCW are:

Do you know how can I use the nand flash?

Thank you

[jb2]

I found the solution in this thread https://community.nxp.com/t5/Layerscape/LS1020a-IFC-not-probed-at-boot/m-p/1488867#M10872 

[kele6ra]

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?
