DFU and custom board.

[Nomi]

On pca10028 dfu_dual_bank_ble_s110_pca10028 example works fine. First i programmed soft device s110 and then dfu dual bank example my board gets into dfu mode and i can upload my user made applicatons using an ios app nrf Toolbox. Now i have made a custom board with nrf51822 with just one led on p0.21 or pin40 of microcontroller. No led2,3,4 and also without any buttons. But now when i upload dfu_dual_bank_ble_s110_pca10028 example on my board it does not advertise. Can someone point out the mistake i am making here.?

Please specify what version of SDK and SD are you using. What is the chip version? What crystals are you using?

[Nomi]

Sdk v8.0. Chip is nrf51822. And i have both crystals on my board 32k and 16M.

What is the exact version of the chip? revision and memory

[Nomi]

its QFAAH00. i have checked the documentation and it says 256kB Flash, 16kB RAM.

The PCA100028 (nRF51 DK) uses a nRF51422 QFAC variant, i.e. 256 kB Flash and 32kB RAM. You have to modify the memory settings in order to run the example on a chip with 16kB RAM. You can edit the memory settings by going to

Options for Target >> Target >> Read/Only Memory Areas and Read/Write Memory Areas

and input the following settings:

IROM1 Start: 0x0003C000 Size: 0x3C00

IRAM1 Start: 0x20002C00 Size: 0x1380

IRAM2 Start: 0x20003F80 Size: 0x80 (NoInit Checked)
