That depends on your uyse case. They have different erase block sizes.

>From the data sheets:

The W39V040FC is a 4-megabit, 3.3-volt only CMOS flash memory organized
as 512K x 8 bits. For flexible erase capability, the 4Mbits of data are
divided into 16 x 8 Kbytes pages and 6 x 64 Kbytes sectors or 8 x 64
Kbytes sectors.

The W39V040FB is a 4-megabit, 3.3-volt only CMOS flash memory organized
as 512K x 8 bits. For flexible erase capability, the 4Mbits of data are
divided into 8 uniform sectors of 64 Kbytes

[Riko Ho]

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...");
