how to get touchgfx project bin without bootloader in it.

[naveen]

Hello!!

iam trying to read a bin file of my touchgfx project which has along with bootloader code in it. while when we generate the bin the linker script is genarate along with bootloader code.

but here i need a only a bin which has application data which will starts from 0x90000000. how can i do this 

why i need? 
i need this becouse i wrote my custom bootloader which will read the data using usb and write it in starting address of 0x90000000 and after successfully written then my code jump from the starting address.

i have tried removing below parameters from project:

BOOTLOADER (xrw) : ORIGIN = 0x08000000, LENGTH = 128k

TARGET(binary) /* specify the file format of binary file */

INPUT (../../ExtMem_Boot/bootloader.bin) /* bootloader bin file path (relative to the output folder)*/

OUTPUT_FORMAT(default) /* restore the out file format */

.bootloader :

{

. = ALIGN(4);

KEEP(../../ExtMem_Boot/bootloader.bin)

} > BOOTLOADER

after that build it and i flashed it in my board using my custom bootloader.

but it's not working as expected. can anyone help me here where i went wrong
