Changing Board, JLink Issue

Kjern

I've recently began testing the NRF51 SDK, however, due to some availability issues, I'm using the PCA10003 Board. I've followed the two Tutorials here, and I am able to get everything up and running without changing any settings. However, I'd like to assert some more control over the board, and get proper access to the GPIO ports, and get the buttons/LEDs working. So I've changed the board definition in the C/C++ settings, and left everything else as it was.

I can build the Tutorial project just fine, but when I try to flash it, I get the following error message:

Load "C:\Nordic Semiconductor\nRFgo SDK 2.3.0.10040\source_code\projects\ble_peripheral\ble_app_uart\pca10028\arm5\_build\nrf51422_xxac_s110.axf" Set JLink Project File to "C:\Nordic Semiconductor\nRFgo SDK 2.3.0.10040\source_code\projects\ble_peripheral\ble_app_uart\pca10028\arm5\JLinkSettings.ini"

  • JLink Info: Device "NRF51422_XXAC" selected.

Erase Failed! Error: Flash Download failed - "Cortex-M0" Flash Load finished at 12:56:41

According to other responses here, it seems as if I'm trying to flash to the softdevice. image description

    The PCA10003 uses an older chip then the PCA10028. So you should compile against target nRF51422_xxAA (not xxAC)

    If you change the target under Options -> Device, the IROM and IRAM settings will be reset, and you need to change it back to the correct ones. See this thread: devzone.nordicsemi.com/.../

    The xxAA chip also only have 16KB of RAM so set the IRAM size to 0x2000 (not 0x6000)

    I think you also need to re-select "J-LINK / J-TRACE Cortex" in under the 'debug' section as well.
