Caanoo / WIZ How To Read Caanoo Serial Number

[Geca]

Hi, it is posible to read the caanoo serial number by code ?
Thanks.

There will be something, because you can see your caanoo serial number in a section of the options menu...

Yep, but how to get them in your aplication ? Some file in the nand with them ?

Have a look at Pollux Databook rev 0.91, chapter 5.
You must to read some hardware registers.

Where is this book ?

I take a look at u-boot 1.1.6 to find the source from the settings panel where the serial is displayed, but i can't find the resource...

I find the book, thanks.

Can you make a example to read one of these registers using pollux ? Thanks..

uboot is the OS loader program, you must to look at the firmware/menu source, if available.

Is a bit complex, but you can see the libcastor initialization source code for reading hardware registers.
You must open the Linux "/dev/mem" device and access the locations of the registers to read the values.
If you know old BASIC language is like using instruction PEEK to read the memory.

You have an example for reading (other) registers in the wiki:

From gmenu2x:

GMenu2X::GMenu2X(int argc, char *argv[]) {
//Detect firmware version and type
if (fileExists("/etc/open2x")) {
fwType = "open2x";
fwVersion = "";
} else {
fwType = "gph";
fwVersion = "";


void GMenu2X::gp2x_init() {
#ifdef TARGET_GP2X
gp2x_mem = open("/dev/mem", O_RDWR);
gp2x_memregs=(unsigned short *)mmap(0, 0x10000, PROT_READ|PROT_WRITE, MAP_SHARED, gp2x_mem, 0xc0000000);
MEM_REG=&gp2x_memregs[0];

batteryHandle = open(f200 ? "/dev/mmsp2adc" : "/dev/batt", O_RDONLY);
if (f200) {
//if wm97xx fails to open, set f200 to false to prevent any further access to the touchscreen
f200 = ts.init();
}
#endif
#ifdef TARGET_WIZ
/* open /dev/mem to access registers */
wiz_mem = open("/dev/mem", O_RDWR);
if (wiz_mem < 0) {
printf("Could not open /dev/mem!\n");
}
/* get access to the registers */
else {
wiz_memregs = (volatile uint32_t*)mmap(0, 0x20000, PROT_READ|PROT_WRITE, MAP_SHARED, wiz_mem, 0xC0000000);
if(wiz_memregs == (volatile uint32_t*)0xFFFFFFFF) {
printf("Could not mmap hardware registers!\n");
close(wiz_mem);
}
}
/* get access to battery device */
batteryHandle = open("/dev/pollux_batt", O_RDONLY);
printf( "System Init Done!\n" );
#endif

You can read the ID only in the Wiz or Caanoo, not in GP2X because uses other SoC. And you must to access the register addresses specified in the Pollux databook.
