Question about errors encountered using mmc_test

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello all, I'm new to the mailing list, so please forgive if this
question is out of line.

I'm trying to run the suite of MMC tests from mmc_test, using the
directions found here:

http://wiki.laptop.org/go/Tiny_Core_Linux/eMMC

When I get to the last step, "for x in $(seq 45); do..." I get an
output full of the following message:

-bash: test: Permission denied

Not surprisingly, this message is output 45 times.

What I am trying to do is debug an interface to an MMC chip on new
hardware.  I tried to use parted to create a partition table.
Basically I try to make a label first, with

mklabel gpt

and that command "doesn't complain".  But then I try to make the table using:

mkpart primary ext2 0 -1s

And I get the message:

Error: Unable to open /dev/mmcblk0 - unrecognised disk label.

For most commands I get this same message.

So any advice or suggestions are appreciated.

Andre
