HW setup is my boart connected to a windows10 PC with an uart link.
I tried secure_bootloader_pca10100_uart_ses_nRF5SDKThreadv4.1.0.zip example, with some modification for my board, es UART pins in custom_board.h
#define RX_PIN_NUMBER 7
#define TX_PIN_NUMBER 6
//#define TX_PIN_NUMBER 35
#define CTS_PIN_NUMBER 8
#define RTS_PIN_NUMBER 40
#define HWFC true
To validate uart pins changes I tested the uart example in examples\peripheral\uart\pca10100\blank\ses and it works fine both without HW flow control and with HW flow control.
When I send
nrfutil dfu serial -pkg blinky_pca10100_mbr.zip -p COM5 -b 115200
it seems all freezed: RTS signal from PC goes low, but nRF52833 RTS pin remains high. If I force low that signal PC starts transmitting.
A second question
The DFU example uses (in sdk_config.h) Button for entering DFU mode and set NRF_BL_DFU_ENTER_METHOD_BUTTON_PIN to 25: in my board I cannot access to that pin and I want to use PIN0.2.
I set in custom_board.h
#define BUTTON_4 2
and in sdk_config.h
#define NRF_BL_DFU_ENTER_METHOD_PINRESET 1
I add Enter DFU mode on pin reset
Is it correct ?
How can I debug the DFU example ?
Best Regards
