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

Thanks! Ok, now I think that i understand more. If you are using the bootloader from SDK v12.2.0, then the FLASH Origion + the FLASH length == Bootloader start address

In the default bootloader from SDK v12.2.0 starts at 0x7A000, so the length of the flash for the application should be set to 0x3AC00- 0x1B000 = 0x1FC00

So the issue is that the ble_dfu_init function return a non-zero error code? If yes, which error code is it? 

Are you still seeing the FDS_ERR_NO_PAGES being returned by fds_init when initializing the Peer Manager module?( call tree peer_manager_init() -> pm_init() ->pds_init()-fds_init()?

In the SDK v12.2.0 buttonless dfu example peer_manager_init() is called before the services are initialized. So please make sure that you call your dfu_init() function after ble_stack_init() and peer_manager_init(). 

Best regards
