ANT on PCA10056 and custom board ?

[RixtronixLAB]

Dear Members,

I want to run ANT+ code in my custom board,

It works well on PCA10056, I can upload softdevice and the code to custom board board,

but I didn't get any responses,

I have tried with code without softdevice, the custom board works well

Any ideas ?

Thanks

Hello,

Does your custom board have a 32KHz crystal mounted? If not, you have to make sure you select the internal RC oscillator when you enable the Softdevice. Otherwise, the Softdevice will enter an infinite loop waiting for the crystal to start.

The memory layout should be left as is.

Best regards,

Vidar

Does softdevice require VDD HV? I connected VDD HV to 3.3V .

Did you place the breakpoint like I asked?

I did :

?

OK, thanks. Please include the CPU register view as well so I can see where it hangs.

Can you read out the first word from address 0x0? It doesn't look like you have a valid Softdevice present.

ANT_s340_nrf52_7.0.1.hex ?

Yes, it's valid, but it doesn't make sense that all registers are read as 0. When did you pause the debugger?

You need to pause the debugger by pressing the red stop button when the program hangs, then read the cpu registers.
