I testing UART0 data transmossion. But, could resolve why CPU resets when executing : if (!nrfx_is_in_ram(buf)) in uart_nrfx_uarte.c file. See atached image, where Reset occurs.
Hi, there is function in my code : send_uart0(unsgigned char *buf). This function works very well in whole program and has been used many times to send data to URAT0. But, at a particular only, it causes such error. The same has been varified to be in RAM. The buf has been allocated at compile time.
