DFU using BLE

[Khazragy]

Hello all,

I am trying to update my firmware using BLE peripheral. I followed the instructions in this [tutorial] (devzone.nordicsemi.com/.../)

I downloaded the SoftDevice then downloaded the DFU example "dfu_dual_bank_ble_s110_pca10028"

Then I am trying to connect to the device by nRF Toolbox (DFU) but I can't!!

I spent a lot of time debugging and I found that the software is stuck inside "HardFault_Handler" and the last function before it loops infinitely was "crc16_compute"

Could anyone help ?

Good day Khazragy

Which devkit and SDK version do you have?

[Khazragy]

I mounted the chip onto my own PCB, I am not using a devkit, and related to the SDK version I am using v10

Which softdevice did you program to the chip, S110 v.8.0.0?

Do you see the same problem if you test DFU with nRF Master Control Panel?

[Khazragy]

yes, I am using softdevice S110 v.8.0.0, do the versions of SDK & Softdevice should be compatible ?

I didn't test using nRF Master Control Panel, I think this is the next step I shall do if the App phone wouldn't work! But anyway I need to know the issue using my smart phone.

When going from QFAC to QFAA (32 kB RAM to 16 kB RAM), the linker settings have to be changed to the following:

The hardfault occurs when the bootloader tries to read data from 0x20007f80. It therefore have to be changed to 20003f80.

Let me know if it still doesn't work.
