Thank you, Kyösti, for the reply. I tested the modified Coreboot by 115200 Buad rate, again the same message(latest post code seems to be 0x11)(modified Coreboot contains sdram_enable() changed and some fuction calls was commented out in romstage.c and i am using build/coreboot.rom as the final image on ROM chip):

I can verify that by the assembly code i have. writing to any memory location and reading that. Also I tested it by ram_check() in Coreboot. Both are correct.
The last post codes are 0x39, 0x80 and Coreboot seems to stop!
Hi
0x80 seems like a reasonable POST from the very beginning of stage coreboot_ram. Continue your work with src/boot/hardwaremain.c; figure out whether you only lose serial communication or if the execution actually halts.
Seems there is a case or two of possible infinite while() loops within the uart8250 serial console code. This is a wild guess, but the uart could end up in a bad state if transmit buffers are non-empty while divisors are programmed etc. Maybe raise the speed to more common and tested 115200.
