hci dfu custom pcb bug

[PY]

Hi everyone,

I am trying to update my nrf52832 chip with another MCU using UART.

I am using the bootloader example dual_bank_serial_s132 with the s132 SoftDevice.

I have tested it on the DK and everything works fine but when I do it on my custom PCB nothing happen. I have read the Tx pin of the nrf52 and it sends nothing.

I have allready checked the pin numbers of my custom board and I put the good ones. (I can upload my BLE application without bootloader and it works and the uart too)

Does anyone has the same problem ?

Update: That was my bad, I am not using externall ocillator so I had to modify my clock source in ble_stack_init() function.
