Hello everyone,

I am using MQX4.1 CW10.6 & MK60FX512VLQ12 controller on our custom board.

I have tested nandflash demo example on TWRK60F120M & is working fine.Now I am trying it on my custom board & getting output as

MQX NAND Flash Example Application

I have done clock setting

Re: FFS on NANDFLASH of TWR-K70 (MQX 4.0.1)

this is also not working.What may be wrong in this.

Any solution?

Thanks for the help.

Hi T tech;

It is necessary to check the hardware connections; does the custom board have the same hardware connection than the TWR-K60F120M?

We have non-MQX project for NAND Flash Controller(NFC). please use the KINETIS_120MHZ_SC sample code to evaluate nfc. This is in order to isolate the issue.

Please download the code from the link below:
https://www.freescale.com/webapp/sps/download/license.jsp?colCode=KINETIS_120MHZ_SC&appType=file2&location=null&DOWNLOAD_ID=null
see path ..\KINETIS_120MHZ_SC\KINETIS_120MHZ_SC\build\cw\nfc

Have a great day,
Sol

Hi Sol,

Thanks for the reply.

Hardware connection is same as TWRK60F120M.

Done some touch up to MK60FX512VLQ12 & now its working fine.

Thanks.
