ble_app_uart won't advertise as coded from example set

[Alexandre Tessier]

Hello, I am currently trying to program the uart example code from the nRF5_SDK_12.3.0_d7731ad zip file. After dealing with various reference address and device package issues, I am now able to flash the softdevice and progam sets to the chip. However, the chip is not advertising and it does work with the premade hex file. At this point I have no idea what could be wrong, the only noticible difference between the hex file layout in nRF Connect and the flashed softdevice and code from Kiel 5 is shown in the attached image, with hex file on the left covers the register address from 0 to 0x0001E3F7 while the flashed program from Keil goes from 0 to 0x0001E3FF. Other than that the recovery error is shown in the command window, but this occured even for the hex file which would advertise so I am unsure how to proceed.

Hi

Have you made any changes to the ble_app_uart example project? Does the build and flash procedures in Keil complete without any errors? Can you show me the build logs from Keil as well?

Best regards,

Simon

I went to verify something and now the Jlink-Cortex M error has returned. I thought this was finally resovled but it would appear not to be the case. I was able to flash the softdevice, so it seems to only be related the actual code itself. Was able to flash the blinky program onto the board.

Intersting development, when I shift the IROM1 start from 0 to 1B00, the blinky program no longer works. Why is this? I had changed the start address for the uart because it would overlap with the softdevice code. If changing the register so this does not happen causes it not to work, what am I suppose to do?

I was able to fix the Cortex M error by changing the Port from JLink to SW.
