Inconsistent Data on UART output terminal from Sockit Cyclone V SoC board

Hi

Thank you so much for your follow up. Everything is fine now. You can close this case.

Hi,

I did not find the attached file, can you re-sent them again?

Thanks.

Hi @EberL_Intel​

Sorry for late reply. I was ill during the whole week that is why couldn't reply you. Can you send me your email address so that I can send you the files. The c code I have attached herewith

void* virtual_base; /*pointer to open device memory file*/
 
int main ()
{
	
int fd = EXIT_FAILURE;	
 
fd=open("/dev/mem",(O_RDWR|O_SYNC));
if (fd < 0) {
		perror("open");
		exit(EXIT_FAILURE);
			}			
printf("fd is ok\n");
 
virtual_base=mmap(NULL,REG_SPAN,(PROT_READ|PROT_WRITE),MAP_SHARED,fd,REG_BASE);
printf("virtual base pointer to open device memory file is ok\n");
 
reg_addr = (unsigned int *) (virtual_base+NEW_COMPONENT_0_BASE); /*accessing base address of register*/
while(1)
{
printf("pointer value is %d\n", *reg_addr);
}
return 0;
}

Hi,

I would like to know if you still facing the inconsistent issue?
