using flashloader, elftosb and mfttools - boot_image.sb binary generated is 0KB

[palak_shah1]

Hello,

I am using iMXRT1064 EVK board. I want to use the flashloader utility suite (elftosb and mfttools) to burn an image on the flash. 

I am following instructions on this link - 

https://community.nxp.com/t5/i-MX-RT-Knowledge-Base/Generating-a-Bootable-Image-for-the-RT1050/ta-p/...

I want to create an image that can run from SRAM and follow this commands -

In the MCUxpresso, I use evkmimxrt1060_igpio_led_output example from the SDK. 

I followed the instructions to create .srec file. 

Please note that I dont have a dcd.bin file and so I have XIP_boot_header enable and XIP_boot_header_DCD_enable both to 1.

Below is the output generated - 

I copy the .srec file to the flashloader utility folder and follow the instructions -

However, the output file generated (.bin and boot_image.sb)is 0 KB. 

Can you please tell me why the output files are 0 KB. I tried the flexspi_hyperflash SDK example as well. And same result. 

Am I using wrong commands?

Any help appreciated. 

Thanks,

Palak

Hi,
Similar to the below commands.

elftosb.exe -f imx -V -c ../../bd_file/imx10xx/imx-dtcm-unsigned.bd -o evkbimxrt1050_led_blinky.bin led_blinky.s19
elftosb.exe -f kinetis -V -c ../../bd_file/imx10xx/program_flexspinor_image_hyperflash.bd -o boot_image.sb evkbimxrt1050_led_blinky_nopadding.bin

Have a great day,
TIC

I tried this exact same command that you pasted - 

elftosb.exe -f imx -V -c ../../bd_file/imx10xx/imx-dtcm-unsigned.bd -o evkbimxrt1050_led_blinky.bin led_blinky.s19

 and it generated the image which is 0KB. 

Why is the .bin file empty?

Hi,
Thanks for your reply.
Firstly, I'd highly recommend you go through the post carefully, next, my command is just a sample, you need to provide your own S19 file and the return message already notified you should provide an S19 file.

Have a great day,

Hi,
Thank you for your interest in NXP Semiconductor products and for the opportunity to serve you.
1) Please modify the address the below figure shows;

2) I'm a bit confused with the commands you used, I think you'd better refer to the post carefully, actually, it only needs to input two commands to generate a correct SB file.
Have a great day,
TIC
