continuing the chat, for displaying "Hello world" on serial #define CLKIN_DEV PNP_DEV(0x2e, IT8718F_GPIO) void mainboard_romstage_entry(unsigned long bist) { ite_conf_clkin(CLKIN_DEV, ITE_UART_CLK_PREDIVIDE_24); ite_enable_serial(SERIAL_DEV, CONFIG_TTYS0_BASE); .... How can I write "Hello world !" ? and where ? Could it be : ite_conf_clkin(CLKIN_DEV, ITE_UART_CLK_PREDIVIDE_24); ite_enable_serial(SERIAL_DEV, CONFIG_TTYS0_BASE); printk(" HELLO WORLD ! FROM COREBOOT..."); ......

It's in SerialICE project, not in coreboot project. On 2016年10月17日 10:23, Antonius Riko wrote: > I can not see > D946GZIS > > on my src/mainboard/intel ....where is it ? > > >

I didn't see carefully that coreboot has 946....hopefully it will help me a lot...I need to see it's superio and southbridge then...

Diassemble i946GZ ?
by Riko Ho 17 Oct '16

Everyone.. What's the process on diassembling i946GZ ? How can I do that from my original motherboard ? so I can see the init process of this northbridge ? How can I use SerialICE doing it ? I want to know the process downloading the code from the original motherboard, and run it on Qemu ? and capture the init process for northbridge ? Does anyone have the reference ? Thanks

Comparing : http://ark.intel.com/products/34505/Intel-82945GC-Graphics-and-Memory-Contr… http://ark.intel.com/products/27725/Intel-82946GZ-Graphics-and-Memory-Contr… they have the same job....but I'm not sure if they have the same init code...if I'm lucky, they have the same init code, only I will miss some features from 82946GZ if I'm using the code from 82945GC... How do you reckon ?

Ok, is W39V040 FCPZ compatible with W39V040FB ? on my original board is FB series...my spare chip is FC series.... How can I diassemble the original flash with SerialICE and run it on Qemu ? I have written onto my FC series chip, but I want to see the original one running on qemu, since the chipset I have on coreboot it different, onboard is intel 82946GZ and on coreboot I'm using intel82945GM, but super IO and southbridge are supported by coreboot So I want to copy / download the original one and simulate it on qemu then disassemble northbridge init code and rewrite it for coreboot...

Ok, I can burn it already as *.bin....now what do I expect to run from serial ? what 's the baud speed ?
