Hello Kristin.. I'm very grateful to you for all your help You are right, Ram should end at 0x20003f80 , I erased the chip changed the ram size , compiled and put the softdevice then the bootloader. But it still doesn't work!!

No even before starting to upload the new firmware, I can't connect to the device, the BLE is not advertising.

My board is "Wireless-Tag WT51822-S2", it is a module that uses nRF51822-QFAA as (SoC) so it isn't a devkit.

I used the DEBUG option and tried to go through the software step by step, and found that the last called function before the HardFault is crc16_compute.

The function contains a for loop so if I put a break point after the loop, the software goes dead inside the HardFault trap, But if I step inside the for loop until it finishs, the software jumps to the function "app_error_handler" and stuck into the while(loop);

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.

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.

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?

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

Good day Khazragy

Which devkit and SDK version do you have?
