Bootable_image size is 0 (SDRAM)

[jimhuang2]

Hello, I want to generate bootable_image as boot code. When boot time, the boot code will run sdram.

Issue:  The boot_image size is 0 by the elftosb tool (win)。

Env: RT1050 EVKB, QSPI Flash (IS25WP064A), SDRAM(IS42S16160J-6BLI, 256Mb)

Generation Bootable image flow: (https://community.nxp.com/docs/DOC-341317)

STEP1. Create new project(example code: rt1050_iled_blinky).

Set MCU Setting -> Flash driver (IS25WP064A).

Modify SDRAM location 0x80002000 address.

STEP2. XIP_BOOT_HEADER_ENABLE=0, XIP_BOOT_HEADER_DCD_ENABLE=0

STEP3.  Go to C/C++ Build >> Settings >> MCU Linker >> Manage linker script, and check the box Link application to RAM.

STEP4. Build (Check SDRAM space)

 

STEP5. Generate an SDRAM_iled_blinky_boot_image.s19 (.s19)

STEP6. Download boot_to_sdram.zip (https://community.nxp.com/docs/DOC-340655)

The imx-sdram-normal-unsigned-dcd.bd put Tools > bd_file > imx10xx      

 The dcd.bin put Tools > elftosb > win

STEP7.  Use elftosb tool to generate image file, Execute Command prompt (administrator mode)

elftosb.exe -f imx -V -c ..\..\bd_file\imx10xx\imx-sdram-normal-unsigned-dcd.bd -o evkbimxrt1050_led_blinky.bin SDRAM_iled_blinky_boot_image.s19

       Generate evkbimxrt1050_led_blinky.bin & evkbimxrt1050_led_blinky_nopadding.bin

elftosb.exe -f imx -V -c ..\..\bd_file\imx10xx\program_flexspinor_image_qspinor.bd -o boot_image.sb evkbimxrt1050_led_blinky_nopadding.bin

 

#

STEP8.  Found boot_image size is 0.

Best Regard,

Jim

Hi Jorge Alcala

Currently, the project will not use this method for the time being,

Thank you very much.

Hello,

Currently, After the following steps, the board has no work.

Step7. I can generate a boot_image.sb (24KByte).

elftosb.exe -f imx -V -c ..\..\bd_file\imx10xx\imx-sdram-normal-unsigned-dcd.bd -o evkbimxrt1050_led_blinky.bin SDRAM_iled_blinky_boot_image.s19

elftosb.exe -f kinetis -V -c ..\..\bd_file\imx10xx\program_flexspinor_image_qspinor.bd -o boot_image.sb  evkbimxrt1050_led_blinky_nopadding.bin

       Step8.  Copy the boot_image.sb file to Tools > mfgtools-rel > Profiles > MXRT105X > OS Firmware.

       Step9.  Set SW7 on the board to OFF-ON-OFF-ON,

       Step10. The mfgtools-rel upload the bootable image to the board .

       Step11. Set SW7 to OFF-OFF -ON -OFF to boot from QSPI Flash.

      I don’t know where the problem is.

Best Regard,

Jim

Hi JingHuan Huang

You could perform an attach to the running target to read the memory and verify if the SDRAM was correctly initialized. This seems to be a problem with the binary file that you are loading could you share the project that you uses and the offset that you set?

Hi JingHuan Huang 

The second command of elftosb need to have the kinetis parameter, not the imx.

elftosb.exe -f imx -V -c ..\..\bd_file\imx10xx\program_flexspinor_image_qspinor.bd -o boot_image.sb evkbimxrt1050_led_blinky_nopadding.bin

it has to be

elftosb.exe -f kinetis -V -c ..\..\bd_file\imx10xx\program_flexspinor_image_qspinor.bd -o boot_image.sb evkbimxrt1050_led_blinky_nopadding.bin

Hope this helps

Best regards
