The UartSecureDFU SDK failed to send the upgrading aplication.zip to 52832 in Linux system!

 Hi 

        I build the UartSecureDFU SDK to output a Window's EXE file, it send the upgrading aplication.zip to 52832 successfully in Window 7 System. But If build  the UartSecureDFU SDK to output a Linux binary file,It  failed to send the upgrading aplication.zip to 52832 in Linux system (Ubuntu 14.04)!

 I debugged,it enter the uart_drv_send method in uart_linux.c , and then It is waiting in the if (tcdrain(p_uart->tty_fd)) all the time。At the meanwhile ,The 52832 has no received any bytes.

Please help me analyse it!!!

Thanks

Hi,

I'm not familiar with this implementation, unfortunately. Have you tried doing this with nrfutil (DFU over a serial UART connection) to see if that worked? Or if you have verified PC communication through the UART interface with the UART Example?

Hi Vidar Berg:
I have tried it that the nRfutil tool can work and verfied the communication between the PC and UART interface is connected.
But I need one tool which can work in linux system.Because my nrf52832 chip is sticked to the android mainboard and
I will pre-build it into android system.So can you give me some ideas?
Thanks
Best Regards!

Did you confirm UART communication on the Android system? Also, does the serial port show up in /dev/ and have you tried running the script as root?
