Hi Sebastian,
I try to cover your case.

if (are you using uarlite IP?) {
	if (check in mhs: uartlite baudrate a check your baudrate on serial terminal == the same) {
		printk("run testing memory application and see results. I hope you see output.\n");
		if(check if fs-boot is placed to BRAM(green icon) == in BRAM) {
			printk("run xmd and connect via MDM to FPGA\n"
				"connect mb mdm, mrd 0x0 0x100, mwr 0x0 0x12345678 0x100, mrd 0x0 0x100);
			if (do you see the same value(0x12345678)?) {
				printk("find your fs-boot.elf file\n");
				printk("XMD: dow fs-boot/fs-boot.elf\n"); /* write your path */
				printk("XMD: run\n");
				if (do you see FS-boot output?) {
					printk("congratulation - you win\n");
				} else {
					printk("check mss file stdin and stdout == name of uartlite IP");
					and start again with compilation of application
				}
			} else {
				printk("your BRAM memory cheat you - rebuild your EDK project and start again\n");
			}
		} else {
			printk("placed fs-boot to bram and start again\n");
		}
	} else {
		printk("change baudrate to same value and start again\n");
	}
} else {
	printk("change serial output to  uartlite IP rebuild EDK project and start again\n");
}

Cheers
