why DFU mode not entered after flashing softdevice and bootloader

[makouda]

I'm using SDK 9, I flashed the softdevice 8.00

I compiled the project located in \SDK_9.0.0\examples\dfu\bootloader\pca10028\dual_bank_ble_s110\arm5_no_packs

I flashed the hex file in bootloader region but my device didnt work (I cant see DfuTarg advertising)

I use nrf51 256kb and 16kb ram, is there any modifcation should I perform in target option?

reading 0x10001014 flash address gives me 0x0003C000

I jointed the memory dump and hex file programmed in flash with softdevice 8.00 and bootloader compiled with sdk 9

memory dump.txt FLASH.hex memory dump, flahs app with {BANK_VALID_APP}, .txt

I meet almost the same problem! I can see the advertisement but when I click the DFU, it disconnect! I guess something wrong in the IROM1,IRAM1 or IRAM2!

[makouda]

Are you talking about ROM addresses or the ROM itself (I mean corrupted)

[Bill]
