Hello, I am facing an issue using the elftosb tool in Windows.
I want to generate a .bin bootable image (as a precursor to generating the sb file) using elftosb for the Hello World SDK demo project on MIMXRT1060-EVK.
From the flashloader documentation, I have tried executing the following command, but the size of output.bin is always 0.
elftosb -f imx -V -c imx-flexspinor-normal-unsigned.bd -o output.bin evkmimxrt1060_hello_world.elf
And here's the bd file I am using. It came with the flashloader release files.
Since this is a program file (and not flashloader), it needs to be loaded into Flash whose address is 0x60000000. Also NOR FlexSPI offset is 0x1000 according to the reference documentation.
I am using QSPI Flash.

options {
flags = 0x00;
startAddress = 0x60000000;
ivtOffset = 0x1000;
initialLoadSize = 0x2000;
//DCDFilePath = "dcd.bin";
# Note: This is required if the default entrypoint is not the Reset_Handler
# Please set the entryPointAddress to the base address of vector table
// entryPointAddress = 0x60002000;
}
sources {
elfFile = extern(0);
}
section (0)
{
}
The .elf file (attached) was generating in MCUXpressor by changing the artifact extension from 'axf' to 'elf'.

What am I doing wrong here? 
I am also attaching the evkmimxrt1060_hello_world.elf.
