Re: [U-Boot-Users] Error reading environment with fw_printenv

I'm running fw_printenv tools on the target (ARM9 running Linux 2.6.9-rc2).
MTD partitions work fine (tried to read some bytes with dd).
Can you read the envrionment sector (use a  combination  of  bs+  and
skip= options with "dd" to get the right offset) ?
...
When the function flash_io (fw_env.c) tries to read the CRC and the flags,
the function read reads just one byte instead of 5 as specified
by len parameter ((line 538)):
You mean the return code of read() is 1? Can you show me  the  strace
output for this?
...
Is it correct to assume that the read actually reads the specified number 
of bytes?
On a MTD device it should, unless it encounteres EOF. Are  yoiu  sure
your configuration is OK?
Best regards,
