Dear Rahanesh,

When i executed fw_printenv on an embedded board , it threw an error
IOCTL error : Cannot get MTD information!! Any idea why this error occurred?
Well, looking in the source code, I see a single place with a similar error message:
786 rc = ioctl (fd, MEMGETINFO, &mtdinfo); 787 if (rc < 0) { 788 perror ("Cannot get MTD information"); 789 return -1; 790 }
But then, the error message would be:
Cannot get MTD information: XXX XXX XXX
with "XXX XXX XXX" giving an explanation of what goes wrong.
What was the "XXX XXX XXX" that got printed in your case?
The contents of config file which i used shown below
# MTD device name Device offset Env. size Flash sector size Number of sectors /dev/mtd0 0x0000 0x1000 0x10000
Are you sure this is correct? Your environment size is only 4 KiB? And your flash secor size is 64 KiB?
Best regards,
