Migrating from Keil to SES - Error with DFU INIT service

[KrishNa]

Hello Guys,,

I am trying to migrate my project form keil to segger embedded studio. My product is based on sdk 12.2.0, using softdevice s130 on nrf51822.
I searched for all the posts that helped in migrating to SES and able to successfully build my application project. But when flashing the build to my board
it is getting stuck at nrf_dfu_flash_erase function in dfu_init

I tried debugging and it is giving the error FS_ERR_INVALID_CFG in check_config(p_config) function. searched for the solution in the forum posts but nothing helped so far.
please help us to resolve as we are nearing production.

I am attaching my flash placement file for your reference

See function brief above: FDS_ERR_NO_PAGES -  If there is no space available in flash memory to install the file system.

How large is your application? There needs to be atleast two empty flash pages at the end of flash (if no bootloader is used) or two empty flash pages below the bootloader if a bootloader is present.
