Hello, 

We need your support in the following topic. 

The KW37/38/39 is used in our projects and need to be tested according to BT spec. in non-signaling mode. 

As I know, for Hardware verification (RF Performance), we need to flash the HCI_blackbox application to the target. 

 

According to NXP system engineer: Because the target is still blank, we should first flash the blootloader application (using th SWD signals) in order to use the UART and SPI interfaces 

1- Could you please provide a detailed explanation or AN which describes the steps how to flash the bootloader application to the target and then the hci_blackbox.

We have access to: 

PTA0 (SWD_DIO) / PTA1 ( SWD_CLK) 

PTC2 (UART_RX) / PTC3 (UART_TX).

 

2- Which connector need to be used to connect the IC (SWD) to the PC

 

Thanks and regards

M.Swaidan
