Hello,
it is possible to use Winbond spi flash support 25q128fvsg. If yes where I can find some information about how to prepare an image for it? Thanks

Hello there,

I am trying to use your sd card images on my LicheePi Zero Dock, as you guided, I just write with dd command and that is not working because of the same error which mentioned older issues here.

And I tried to compile kernel & u-boot, now my setup used zImage to boot up. But the file systems you created using modversions, which affects my modules. Even I change the kernel name so that same with yours, that time system disagrees about version of modules. Is there any way to flash your file system with no error or is there any advice to get rid of this situation ?

Thanks in advance, sincelery.

Hi. I'm trying to go straight to the registers, but nothing works. What am I doing wrong ??

#include <sys/mman.h>
#include <stdio.h>
#include <fcntl.h>
#include <sys/types.h>
#include <unistd.h>

int main(){
printf("new program");
char dev_name[] = "/dev/mem";
int gpio_base;
int fd = open(dev_name, O_RDWR|O_SYNC);
if(fd<0){
printf("open %s is error\n",dev_name);
return -1 ;
}
int sz = getpagesize();
printf("\ngetsize = %u\n", sz);
printf("str = %x ",(0x1c208d8/sz) * sz);
volatile unsigned int str = (0x1c208d8/sz) * sz;
/
unsigned char buf[100];
lseek(fd, 0, SEEK_SET);
lseek(fd, 0x1c208d8, SEEK_SET);
read(fd, buf,1000000);
*/
for(int i = 0; i < 200; i+=1)
{
/*if ((int)(buf[i] <<3| buf[i+ 1] <<2| buf[i+2] << 1| buf[i +4]) == 0x7$
{
printf("ok");
}
*/
printf("\n %x \n", gpio_base[i]);
}

////*gpio_base_out &=0xfffffff8;
////*gpio_base_out = 1;
int mum = munmap(gpio_base, 0x32);
if (mum== 0)
{
printf("\nOK\n");
}
else
{
printf("\nNO OK \n");
}

if(gpio_base == NULL){
printf("gpio base mmap is error\n");
close(fd);
return -1;
}

return 0;

}

Hi Zepan,

I just purchased one of your Lichee Pi Nano's and trying to get it to work with an sdcard. Are these rootfs's still available to download from somewhere?

rootfs-brmin.tar.gz - is the most streamlined root file system with only 1.5M
rootfs-brpy.tar.gz - Based on brmin, the python environment
rootfs-minmin.tar.gz - debian (including apt, network)
rootfs-mindb.tar.gz - debian (including apt, network, gcc, python...)
rootfs-minX.tar.gz - debian( Include desktop system)

Thanks.
