etmsync Pirelli IMEI retrieval: fix poor use of printf() Bug reported by Vadim Yanitskiy <fixeria@osmocom.org>: the construct where a static-allocated string was passed to printf() without any format arguments causes newer compilers to report a security problem. Given that formatted output is not needed here, just fixed string output, change printf() to fputs(), and direct the error message to stderr while at it.

#include "types.h"

extern const u32 _Magic_words[2];

main()
{
	/* 13 MHz to the peripherals */
	*(volatile u16 *)0xFFFFFD02 |= 0x40;
	uart_init();
	printf("Flash boot test program running (mode %u)\n", _Magic_words[0]);
	for (;;) {
		putchar('=');
		if (command_entry())
			command_dispatch();
	}
}
