QN908x BLE and USB together - linker script and startup file

[kishans]

Am trying to club USB and BLE functionality into one  QN908x projects and able to do so in the source , compiler, assembler configuration section. But am not clear how to configure the linker file and startup file. 
 
Linker file : In the case of QN908x USB sample projects Linker scripts get dynamically generated  and in the BLE sample project linker script is pointed to QN908XC_connectivity.ld. Added the below section into the QN908XC_connectivity.ld apart from this everything else looks  vert similar

GROUP (
"libgcc.a"
"libc.a"
"libm.a"
"libcr_newlib_nohost.a"
)

And then used "startup_qn908xc.c" of USB example as a startup but this build resulted in 43 linker errors like "undefined reference to `__start_NVM_TABLE'".

After this tried "startup_QN908XC.S" of BLE example in the startup and the result was 53 errors , in that 43 errors which was reported earlier is also part in the later.

please guide me on the right way to config the linker script and the startup  source file.

Thank you @nxf56274 for the link.

 I was able to resolve the above mentioned issue by taking BLE project as the base and then adding USB project code into it. 
 Updated preprocessor and Heap memory.
