How to boot RT1176 from Serial NAND NAND(W25N01GVZEIG) to SDRAM (32bits 64MB).

How to boot RT1176 from Serial NAND NAND(W25N01GVZEIG) to SDRAM (32bits 64MB).

1) IDE using the MDK

2) Using the SDK M7 APP helloworld demo. and select the SDRAM-TXT-DEBUG

     SDRAM debug( DAP link is OK).  serial port can find the "hello world!"

3) Generate the HEX file

4) Using the MCU boot Utility V5.2.1,

When BMOD[1:0] = 2'b00 (Boot From Fuses), no app in boot device, MCU enters serial downloader mode directly
When BMOD[1:0] = 2'b10 (Internal Boot), MCU boots app according to both BOOT_CFGx pins and Fuse BOOT_CFGx

FLASH hellow  SPI nand.  ( boot mode[1:0] == 10, config1[7:6] == 11) 

cannot boot from SPI nand.

My requirments:

1)  ROM store in the SPI nand.

2)  boot from SPI nand. and copy the image into SDRAM. 

3)  running.

Hi @pguan 

Please look into this community thread:

NAND FLASH XIP and boot modes

This post is similar to your question.

Best Regards, Miguel.

I also following the "NAND FLASH XIP and boot modes".
and perform following operation. cannot work.

1） According to the requirements，I modified the SCF file according to following

#define m_interrupts_start 0x80002000
#define m_interrupts_size 0x000023FF

#define m_text_start 0x80002400
#define m_text_size 0x001FFFFF

2） And add the following to marco.

XIP_BOOT_HEADER_ENABLE=1,

XIP_BOOT_HE



ADER_DCD_ENABLE=1

3) Generate the image.

4) Using the NXP-MCUBootUtility to download the iamge.

DEV UNSIGNED IMAGE BOOT.

5) Cannot run. ( but MDK debug is OK.)

Hi @pguan 

I did not understand, what do you mean with "Cannot run. ( but MDK debug is OK.)"

Is it possible for you to provide more information?

Best Regards, Miguel.

Thank you for your comments！

5） Cannot run

      means that the system (using the MCUBootutitly flash the NAND）cannot boot from NAND to SDRAM。

      MDK Debug is OK means I can debug the application using the MDK（running in SDRAM)

I think that i would miss some operation or where is mis-understand.

MDK generate the HEX image --> MCUbootutility --> boot from NAND to SDRAM。

Hi @pguan 

Sorry for the late reply,

You must change the configuration of the image to boot from the external SDRAM, refer to chapter 6.2.1.3 Image running from external SDRAM from the secure provisioning tool user's guide.
