[udaybarejiya]

hello

I am using sdk 15.3 example code of DFU (secure_boot loader \ pca10040_ble)

I want to debug code but i can not.I getting error like that "Error Flash Download Failed - Cortex-m4"

I am using s132_nrf52_6.1.1_softdevice .i have using nrf52832 board and Compiler Keil 5

Also i have setting address of IROM1 = 0x78000 and Size 0x6000,  IRAM1 =0x200057B8 and size 0xa848.

Please help me to resolve these query

That is strange. Are you able to program and debug other SDK examples? Have you tried to program the same hex with nrfjprog?

[udaybarejiya]

Before one year ago i had use in sdk 10 example that is working fine

yup if we are using hex file then it's loded successfully.

in my application already we have using in BLE dfu , It;s Working Fine

But i want to make BLE + UART dfu that's why i needed Debugging code.

Can you program other SDK 15.3.0 projects through Keil?

Does the original bootloader example work?

Ans:Yes

Does the original bootloader example work?

Ans:in SDk example code you are given pca10040_ble and pca10040_ble_debug code.

pca10040_ble  it's working fine but i can not debug it because it's limitation.

that's why i am using pca10040_ble_debug example code.and it's not debug code
