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.

Yeah I dont like that too. Maybe worth to do a timeout? Or Loop count? It is always better to boot than to have perfect serial output ;)
But in this case I would think memory is not 100% OK. Worth to check if 1M->3M is OK (this is where coreboot ramstage goes)
Thanks Rudolf
Thank you Rudolf for the reply. 1M to 3M is OK please look at the serial port output:

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):

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.
