Thanks! It was the RAM and Flash size.

The Debugger ist jumping directly in an HardFault_Handler() function! Any conclusion?

" (gdb) target remote localhost:2331 Remote debugging using localhost:2331 0x000002f6 in HardFault_Handler ()"

The data sheet says: "Even though its very small size 8x11x1.2mm, the module integrates decoupling capacitors, 16 MHz and 32 kHz crystals, load capacitors, DC-DC converter, RF matching circuit and antenna in addition to the wireless SoC." and "32bit ARM Cortex M0 CPU with 256kB Flash" and "Integrated 16 MHz and 32.768 kHz Clocks"

I think it should fit!? I used the device name "nRF51822_xxAC", is that correct?

Any suggestion?

Does ISP130301C have the same hardware configuration? DC-to-DC and 32kHz crystal come to mind as the first thing. Or amount of RAM on nRF51 chip is different, not enough on ISP130301C
